Update program on rs-485

[Francesco]

Hello
Can i update my program on PIC18F... on rs485 , How can I do it.
Thank you.

Yes. Just convert one of the bootloaders that is using RS232. You shouldn't need to change much. You just need to handle the transmit/receive enable/disable.

[Francesco]

Thanks for your answer , but can I read the some example?

[Mark]

Look in your examples folder. There is an example of a bootloader there. Also you will find a EX_RS232_485.c file. Study both programs.

Is it old?
Thanks.

What pic are you trying to use?

[Francesco]

I want use 18F6520 or 16F876A.

[Mark]

For PIC16 you need the PCM compiler
For PIC18 you need the PCH compiler

Of course the PCWH contains all the compilers.

I have :
IDE versione 3.40
PCB 3.180
PCM 3.180
PCH 3.180

If you don't have it, then upgrade. You might try and download the trial version. I am not sure what examples they provide with it.

Email CCS support and ask them for the RS485 example and driver files.

RS485.C
EX_RS485.C
EX_RS232_485.C

Give them your name and compiler registration number. If you're a
registered owner, then they might email you the files.
