    It works the part of a baudrate change, when i send the command to the gps

    but i think the following it goes to GPS but for some reason is not set.

    Code:

    When you switch the baudrate you have to set both SPBRG2 and SPBRGH2.

    Try:
    Code:
    SPBRG2 = 160 ' 38400 Baud @ 64MHz, -0,08%
    SPBRGH2 = 1
    Pause 500

    It worked!!! I will post later on what i have done up to now. Maybe i need to set up a small indication when those commands are set. So i know that program is working up to that stage.

    This is the code for changing the baudrate to GPS and the hz rate at 10Hz at the NMEA data.

    Dear all,

    i need you help.

    After removing all the DEFINEs and use only the following

    Code:
    'RCSTA2 = $90 ' Enable serial port & continuous receive
    'TXSTA2 = $24 ' Enable transmit, BRGH = 1
    'DEFINE HSER_CLROERR2 1 ' Clear overflow automatically
    'SPBRG2 = 130 ' 9600 Baud @ 64MHz, -0,02%
    'SPBRGH2 = 6
    'BAUDCON2.3 = 1         ' Enable 16 bit baudrate generator
    and for changing the baudrate and the frequency for the Second Serial,

    Code:
    pause 800 
    HSEROUT2 ["$PMTK251,38400*27",13,10]      ' 38400 boundrate, check MTK manual configuration
    pause 800
    
    SPBRG2 = 160 ' 38400 Baud @ 64MHz, -0,08%
    SPBRGH2 = 1
    Pause 500
    
    ;HSEROUT2 ["$PMTK314,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0*29",13,10]
    HSEROUT2  ["$PMTK314,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*28",13,10]
    pause 100
    
    HSEROUT2 ["$PMTK220,100*2F",13,10]        ' 100(millisecond)=0.1(sec)-->1/0.1= 10Hz
    pause 100
    I found out that on SERIAL TERMINAL on the computer of course i see the data coming from the GPS but unfortunately when i connect an LCD to PIC using the first Serial, the data cannot be displayed.

    It seems that when i use

    Code:
    HSERIN2[wait("$GPRMC")
    the data cannot be read from the GPS to the RX of the PIC.

    I tried to check if there is a problem with the LCD, but i can send text to the LCD.

    I tried to check and use only the DEFINEs with 9600 because the default for the GPS is 9600 and it worked.

    so when i do not use the defines, it looks like that RX port on the PIC doesnt work.

    Could you please help?

    I don't know about other members of the forum, but I got confused.

    Best throw in both codes that work and don't work.

    Do they compile OK?

    Are you sure about your connections?

    Default Re: GPS Project: PIC18F26K22 or PIC18F46K22

    Ioanni,

    thanks for your reply.

    The problem is when i use the code to change on the fly as of the guys on the forum advice, without using the "DEFINE" word.

    So using the registers like in the following code:

    Code:
    'RCSTA2 = $90 ' Enable serial port & continuous receive
    'TXSTA2 = $24 ' Enable transmit, BRGH = 1
    'DEFINE HSER_CLROERR2 1 ' Clear overflow automatically
    'SPBRG2 = 130 ' 9600 Baud @ 64MHz, -0,02%
    'SPBRGH2 = 6
    'BAUDCON2.3 = 1         ' Enable 16 bit baudrate generator
    and later in order to change the baudrate i use the following:

    Code:
    pause 800 
    HSEROUT2 ["$PMTK251,38400*27",13,10]      ' 38400 boundrate, check MTK manual configuration
    pause 800
    
    SPBRG2 = 160 ' 38400 Baud @ 64MHz, -0,08%
    SPBRGH2 = 1
    Pause 500
    
    ;HSEROUT2 ["$PMTK314,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,1,0*29",13,10]
    HSEROUT2  ["$PMTK314,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*28",13,10]
    pause 100
    
    HSEROUT2 ["$PMTK220,100*2F",13,10]        ' 100(millisecond)=0.1(sec)-->1/0.1= 10Hz
    pause 100
    The GPS gets the command and set correctly the new configuration.

    So up to here we are fine. I checked this by using a Serial Terminal and i see that both Baudrate and frequency have changed.

    That means that TX is working well, for the first command to the GPS

    Code:
    HSEROUT2 ["$PMTK251,38400*27",13,10]      ' 38400 boundrate, check MTK manual configuration
    pause 800
    and changing on the fly the Baudrate the following command to GPS is working fine as well with the NEW baudrate.

    Code:
    HSEROUT2  ["$PMTK314,0,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*28",13,10]
    pause 100
    
    HSEROUT2 ["$PMTK220,100*2F",13,10]        ' 100(millisecond)=0.1(sec)-->1/0.1= 10Hz
    pause 100
    [/CODE]

    Now what is the problem.

    I used a uLCD to send the VTG and RCM data to the display as i have done in the past using both SEROUT and HSEROUT2 command (for the HSEROUT2 i used the following code with the "DEFINE" and worked well)

    Code:
    'DEFINE HSER2_RCSTA 90h ' Enable serial port & continuous receive
            'DEFINE HSER2_TXSTA 24h ' Enable transmit, BRGH = 1
            'DEFINE HSER2_CLROERR 1 ' Clear overflow automatically
            'DEFINE HSER2_SPBRG 130 ' 9600 Baud @ 64MHz, -0,02%
            'SPBRGH2 = 6
            'BAUDCON2.3 = 1         ' Enable 16 bit baudrate generator
    Now using the registers without the "DEFINEs" the RX on the PIC seems that it doesnt work, something like it is closed or cannot read data from GPS.

    Forgot to mention that 2 hours now i have tried most of the different settings for the

    Code:
    BAUDCON2 = %xxxxxxxx
    without any luck.

    Compile is ok, the same circuit as when the code is working with the "DEFINE" code.

    Something is wrong with the new code that i change the baudrate on the fly.

    there is something going really wrong. Maybe i need to give more PAUSE time?

    I try that as well.

    Are you aware of what's been commented out in the code you're showing?

    Post the entire code as it is.

    Page 281 of the K22 PIC has all the settings of the BRGH, BRG16, SPBRGx in relation to the system Clock.

    Also, depending whether you have RS232 driver or not you have to set or reset the BAUDCONx bits 4 and 5.

    If you will use on both Rx and Tx pins a driver (like the MAX232) then these bits should be 0. If you connect directly to another TTL serial port then these bits should be 1.

    Thanks for the reply. Yes i will post later today the code. But i understand the logic using MISTERE's calculator for EUART and it worked fine. But As the GPS at default is working at 9600, i need to speed it up to 38400. So at this point baudarate change on the fly needs a different settings.

    I have configured the code in order to change the baudrate as mentioned on my previous posts, and from the SERIAL TERMINAL, on the computer i see that TX from PIC to GPS is working fine.

    But the RX of the PIC looks like is not receiving or is not reading the info.

    In any case i will post the entire code later.

    Thanks once again.

    Try changing this:
    Code:
                DEFINE HSER_CLROERR2 1 ' Clear overflow automatically
    to this:
    Code:
                DEFINE HSER2_CLROERR 1 ' Clear overflow automatically
    You'll definitely be getting overrun errors, so if they're not cleared properly it'll stop receiving.

    I'd also try some a LOT simpler to start with. I'd be amazed if those HSERIN2 commands in your main loop work reliably... one thing out of place and it'll likely take a long time to sync up again (if ever).

    Hi tumbleweed,

    that was the typo mistake really. Now it works. thanks a lot.

    I was stuck for a day! Now i can move forward to the next target.

    Really appreciate your help.

    Dear all,

    as for the last step, changing the baudrate of the GPS on the fly, the same time as the PIC chip it self on PORT EUART 2, i've notice that not all the time the configuration work.

    Sometimes the GPS doesn't get the command. I tried to see if i could get an ACK but couldn't see anything coming on RX.

    Base on the manufacturer datasheet there should be a reply message for every command we send. But really didn't see any reply.

    Is there anything i could do, to help the GPS to receive always the command and not "reject" it? Should i give more time at start up?

    I have already place the following commands on the code in order to check if the GPS has successfully powered up.

    I'd be amazed if those HSERIN2 commands in your main loop work reliably
    I agree with tumbleweeds thought, increasing baud rate to 38k cuts the time available to process that streamed data to one quarter of what was available at 9600 baud . its asking for trouble .
    what possible advantage are you seeking with the higher baud rate ?
    there is great merit in sending data to the serial display as fast as possible but I have difficulty seeing any benefit in getting nmea data at higher speeds.

    now that you have a chip with adequate memory and horsepower why not use a buffer to store and process the sentences?
    This is more entertaining than Free to Air TV

    Hi Richard, to be honest i dont know the way to store and process the sentences , but i will search for it and come back with some question. First i will try to understand the concept.

    Now at the moment i need to speed up the serial communication because i need to use to fastest refresh rate of NMEA data from GPS at 10Hz.

    As from the manufacturer and datasheet of the GPS, if you need to go at 5Hz or 10Hz then you need at least to speed up the GPS communication rate at 38400.

    The SERIN command inside the main look, do not have any issue. Only at the beginning of the initialization and changing the baudrate and refresh rate.

    Apart from that everything else works fine at that rate. At the end of the project which may not be able to complete, i will not use the GPS at 10Hz.

    Now i do some fancy test to see how fast the Speed on the Display can be refreshed. As you better understand than me, in order to achieve that, the GPS data must be at a very high rate and the serial communication as well. Actually is a simple speedometer.

    Thanks once again all of you for your time and effort to help me.

    Do you control power to the GPS?

    The sequence of what to do depends on who powers up first. You probably shouldn't assume that the mcu is powered up and initialized before the GPS. It would be good to know how long the GPS takes to powerup and start sending those initial strings.

    The sequence might look something like:

    - wait several seconds at powerup for the GPS to initialize
    leave the uart set for 9600 baud
    You'll likely miss any initial serial transmissions that the GPS sends you, but that's ok.

    - send a string to the GPS that you know the response for, and wait for that response with a timeout.
    The simpler the better... a single response that's easy to parse would work a lot better than a sequence of responses.
    loop doing this until you have sync with the GPS.

    - now you can switch to 38400

    Hi tumbleweed,

    i think i could control the GPS module via Enable pin.

    The GPS based on the datasheet, powerup and start sending commands after the following PMTKs.

    Code:
    ' -----------------------------------------------------------------------------|  
    '                          [ GPS Initialization ]                              |
    '------------------------------------------------------------------------------| 
    ' When the GPS Module is POWERED ON, then the following sentenses are received.       
    HSERIN2 [wait("PMTK011,MTKGPS*08")]
    HSERIN2 [wait("PMTK010,001*2E")] 
    HSERIN2 [wait("PMTK010,002*2D")]
    I guess that by using the above code, i wait for each of this commands, and the program only continues if those PMKT sentences from GPS has been received and read. Is that right?

    May i use a timeout in there?

    Does the Enable act like a reset? Do you have a link to the datasheet?

    Maybe you could keep the GPS disabled until the main uC powers up and is ready...

    Hmm i need to check that. For the datasheet the gps module is from the MKT with MK3339 chip in it.

    Datasheet is on the following Page on the Links mention PA6H
    https://www.adafruit.com/product/790

    Enable pin has only the MKT3333 chip, which i also have but i wont use at the moment the MK3333 chip.

    Both of those have an NRESET input which is a low-active signal that will reset the module.
    Connect that to one of the pic's IO pins (as long as you're powering the pic at 3.3V).

    At startup, init the uart to 9600.
    Then set NRESET low, delay 1msec, and set it high. They don't have any timing specs for the NRESET input, but that should do it.

    After you get the initial sequence from the GPS then you can switch it to 38400.

    I was checking the manual but at the same time the pcb board, which is an adafruit ultimate GPS. They do have an ENABLE pin but this is not coming from the GPS module but from the mic5225 3.3V legulator.

    So i guess that via EN pin on the regulator we can hold the pin to GND or LOW for a 1ms and will do the job. I think it will work. Thanks a lot once again.

    I would also like to thank you all, because i learn everyday more things step by step.

    Apologize for my limited knowlegde, i know that i cannot help you, and it is difficult for you to understand my questions in order to help me as well.

    Appreciate your patience.....

    The EN to the regulator should work as well, but since that will shut off power to the GPS you should make sure to set any IO pins that are outputs to the GPS to tri-state (ie inputs), or drive them low while you have the power off.

    For the UART TX output that means disabling the uart to get control of the IO pins.

    Also, you may need to pull EN low for longer than 1ms. When the regulator shuts off it'll probably take a while for the GPS 3.3V to drop.

    Default Re: GPS Project: PIC18F26K22 or PIC18F46K22

    What i did, is to have all ports low, until the LCD is powered up. Then i set one of the PIC's port to high to enable the GPS's regulator.

    That's all and it works up to now fine. Should i leave the PIC's pin to high? Or should i add a transistor and use it as a switch to control the EN pin of the regulator? So setting the PIC's pin to high, close the transistor EC to GND, and the EN pin is set to 0. Then release the PIC pin to LOW, and the same time open the EC from the transistor, and enable the GPS.

    But with this method i will have one more component in my final circuit and couple of resistors at B and E.

    EDITED:....................

    I did make the portb.2 as an input after i powered up the GPS. It seems that works the same.

    Code:

    Sorry, I should have explained better.

    The PIC IO pin is fine for driving the regulator ENable input... you shouldn't need any other circuitry. Set PORTB.2 as an output low to power off the GPS, and then set it high to turn on the GPS. Leave it as an output high, otherwise the regulator may shut itself off.

    However, when you have the GPS power off you must make sure that NONE of the PIC output pins that connect to the GPS are high, otherwise the GPS could get partially powered from those logic lines that are sourcing 3.3V.

    The UART TX output pin idles high once the UART is enabled (RCSTA2.SPEN, bit 7 = 1), which I think happens during initialization. With SPEN = 0 the uart TX and RX pins are under control of the ports.

    i havent post for some days now, because i have changed the Display from 1'44 to 3.2 and the old serial interface code from 1'44 to SPE as 4D Systems calls it.

    I have changed also the GPS and the firmware which is configured at 115200 bps. Still the code is very simple.
