Hi, I’ve built this mini lcd message board and it works perfectly !
Now, I’d like to display messages longer than 124 characters. Is it possible to replace PIC 16F630 to, say, 16F636 in order to double the message length ?
If this is possible, can you send me the hex file needed to program the PIC ? (I can also sign an non-disclosure agreement if this is necessary). Alternatively, you can send me the preprogrammed PIC directly, along with instructions about how to pay for it.
Sorry, this is not just a matter of using a bigger PIC.
You would have to re-write the firmware.
For copyright reasons we never supply source or hex code.

… and also to modify the text upload utility in order to accept more than 124 characters…
OK then. Can you re-write the firmware for PIC 16F636, program the PIC, and send it to me by mail ?
Sorry, your request is unrealistic.
Apparantly you have no idea of the work involved in writing, testing and debugging firmware.
A project like the MK158 is at least 40 hours of work.
At the current wages, this would mean a lot of money.
Anyway,
Merry X-mas to you and if we may give a little hint, why don’t you learn how to program PICs ?
Then you could write your own custom firmware…
You are right: I have no idea about writing PIC firmware… I just hoped that the differences between the 2 PICs are minor and involves only a few changes to the source code (in order to accept more characters).
I’ve already programmed a dozen PICs now, the problem is with assembling the code… Well, maybe I’ll find some time to learn…
it could be a joke…
