Hserin

Hi.
I am having a problem trying to receive certain data over one byte using the WAIT ( ) modifier in PBP.
Here is my problem shown below. These are the characters that I receive from a certain chip when I send a reset to it.


Sent data:

HSerout ["AT+RST",13,10]


Received data (HSERIN):


2nd boot version : 1.5
SPI Speed : 40MHz
SPI Mode : DIO
SPI Flash Size & Map: 8Mbit(512KB+512KB)
Ai-Thinker Technology Co. Ltd.
ready



The problem is that I only want to display "ready" on my 2X16 display.


hserin [WAIT("ready"),RX0,RX1,RX2,RX3,RX4]

hserin [WAIT($79),RX0,RX1,RX2,RX3,RX4]

hserin [WAIT("r","e","a","d","y"),RX0,RX1,RX2,RX3,RX4]

hserin [WAIT($72,$65,$61,$64,$79),RX0,RX1,RX2,RX3,RX4]


I tried all these above variations and none work for me. If I use the "." at the end of "Ltd."
in the above example it would work because I would get everything after the "." which is "ready"
Problem is that there are "." before the "Ltd." like at the "1.5" so I get everything after that.

How does one go about doing this. Do I use "WAITSTR". If yes, I have tried and dont quite understand how to use it.
Hope this makes sense.

Help is greatly appreciated.
Thanks

hserin [WAIT("Ltd."),skip 2 ,RX0,RX1,RX2,RX3,RX4]
the skip 2 is for the expected CR,LF {CHR13,CHR10}

Then rx0--4 should be "ready"

Thanks Richard!
This looks good! I'll give it a try.
Don't know why I did not think of this? Over thinking maybe?
Thanks again.

Hi Richard.
I don't quite get somehing with HSERIN. Your first example worked great I got "ready" on my 2X16 display. But after that I cant get
any other replys to work They just sit there waiting.

EG.

I am sending out "AT+CWMODE=1" and my reply is:

AT+CWMODE=1

OK

I would like to start the next command after receiving "OK" so I know the first setting was excepted before I go on to the next.
But for some reason the PIC never "sees" "OK".


Test program:


LCDOut $FE,1,"Setting STA mode"
LCDOut $FE,$C0,"Please wait....."

pause 2000

HSerout ["AT+CWMODE=1",13,10]
hserin [WAIT("OK") ,RX0,RX1,RX2,RX3,RX4,RX5]

pause 2000

LCDOut $FE,1,"Set connection "
LCDOut $FE,$C0,"Please wait....."

pause 2000

HSerout ["AT+CIPMUX=1",13,10]


I never get to "Set connection ". Just hangs on WAIT("OK").

I have tried to go back to start of program in case the reply was missed with this

hserin 100,start, [WAIT("OK") ,RX0,RX1,RX2,RX3,RX4,RX5]

but it will go around and around for ever.

I hate to bother you again but I have spent most of the weekend and I just cant get it.
Any help would be appreciated .

Thanks

the device responds

OK(chr13,chr10) or OK(chr10)

so
RX0=13,RX1=10 and then hserin will wait forever trying to fill rx2-5 because no more serial data is forthcoming


either use a timeout or

hserin [WAIT("OK") ]

With hserin you can receive one byte at a time into a buffer until you see the return character,
and then look at the rest of the command you received.

Okay. Will try tomorrow.
Thanks again for your help.

Thanks for the info! Tomorrow I will try again.
