Hi, due to disabilities, I’m am having a custom pontoon built. What I would like to do is build an auto pilot system that works like this:

the pontoon is manually driven from point a to point b...

Read the post, looked in the 18F24J50.inc file and still not seeing anything that references settiing
CONFIG3L<1>

Yes, I looked at section 16.2.2.1 and it states if I want to use the internal Oscillator by setting CONFIG3L<1>, I just can't find anyone who knows where you set that. Any idea?

Any idea where I can get the 12.5pf capacitors? I have checked all my online suppliers and can't find them.

I saw that sample but I am not sure why I would need to remap pins? I not sure if that is there for something else or just for the RTC. Also, do I need external Oscillator and Capacitors for the...

Ok, I decided to order a PIC18F24J50 that has an internal RTC, Do you know I set/read the clock?

Wow, congrats to all the winners!

I am using a PIC18F24J50 that has a internal RTC, I need to be able to set the time from a VB program over USB, I can get the data from the VB program to the PIC, I just need to to know how to set...

I am using a PIC18F2450 and need real time clock to schedule events, is this possible in the PIC? if not, is there a 28pin PIC with PIC18F2450 specs and real time clock? Is there an external chip...

I have an external 20mhz oscillator. Can you tell me what I need to do to use SEOUT2 and SERIN2 on pins PORTB.5 and PORTB.4?

Ok, here is what I have


DEFINE OSC 20
TRISC = %10111111 ' Set TX (PortC.6) to out, rest in
TRISB = %00010000 ' Set TX (PortB.5) to in, rest outputs
TRISA = %01111111
SPBRG = 25 ...

Doing further research, it looks like I have to use HSEROUT withe the USART pins on the PIC18F2450. I have tested with HSEROUT and I still don't get any serial out.

Can I use other Pins and use...

TRISB = %00000000 is the same thing and that is already in my code.
I don't think Portb has anything to do with my USART operations.

More Information:

TRISC = %10111111 ' Set TX (PortC.6) to out, rest in
TRISB = %00000000 ' Set PortB to outputs
TRISA = %01111111
SPBRG = 25 ' Set baud rate to 2400...

BTW,
the SEROUT PORTC.6,T9600,["This is a test"] command is in a loop that updates every 2 seconds.

I have a Olimex PIC-28 board. I have a PIC18F2450 and a ST232 installed.

I have pin 17 on the PIC18F connected to pin 12 on the ST232
I have pin 18 on the PIC18F connected to pin 10 on the ST232...

Is there any way to send an email from a PIC over WiFi or hard wired Ethernet? If so what PIC(s) do I need? Is there a development board available for testing?

My mistake, ST232

When I connect the RX, TX connections from my PIC18F2450 to my STN232, do I connect
RX -RX, TX-TX or do they cross, RX-TX, TX-RX?

Thanks,
Bob

I need to connect a 24LC128 Serial Memory chip to my PIC18F2450.
I need to read/write 256, 25 byte pieces of data to the memory chip.
I will be reading the data from a PC via USB, as each piece of...

I am using a PIC18F2450. I need to store 256 25byte variables, the Variables will be sent from a PC connected via USB, the PIC program need to read 16 of these and send them out the serial port. What...

PIC18F2450
Is it possible to output a negative voltage on a pin?

Do you know what parts I might need?

No this isn't for serial, I have a device that I need to communicate with that uses only the RTS, DTR lines to communicate. It just counts the pulses on each line.

I am using a PIC18F2450 that is powered with 5v. I need two of my outputs to go to about 7.5 volts or at least a RTS DTR level. What is the best way to accomplish this?

Thanks,
Bob
