PC serial port funny

[mister_e]

OK then, so i'll stop it here and skip the USART interrupt. In meantime, maybe you could use/read some part of what i've include.

What i did is to use a fixed string format using DEC5 modifier on the PIC side

hserout ["aa",DEC5 WordA]

So it always send 7 bytes to the PC

and on the PC side, i split the incoming string in 2 parts

        sWichOne = Mid(IncommingData, 1, 2)     ' get the header (two first character)
        wValue = Val(Right(IncommingData, 5))   ' get the value (5 last character)

Where IncommingData = MSComm1.Input, sWichOne hold the "aa", "bb" or else 2 character header, wValue hold the decimal value after the header.

no big deal.

Bah, why not after all. This one use the USART interrupt. Thanks to Darrel instant interrupts... reduce indeed RTFM sessions to a minimum

Thanks Steve,

I've just opened up the files the files you sent and begin to incorporate into my project. I'll let you know how I went, hopefully all good.


Cheers

Thanks Steve. Eventually got back to my project. (To much time spent on this thing, so the missus says). Anyway, it works a treat. Iv'e added a couple more things to it as now the comms side of it works fine. I am considering using the picf88 for its ADC to measure battery voltgae.

Thansk again Steve,

John

Listen to her! Mister_e (and Darrel Taylor) can attest to the "life ruining power " of the humble PIC if not dealt with in moderation.

LOL,

I wish that I had learnt this trick in the beggining!! LOL
