Web platform / Re: Add 4 serial RS-232 ports
Thanks for both answers.

The devices work in round-robin mode. PIC is always the initiator and sends the request (query the device), device responds with 16 to 32 bytes long message. In the main loop PIC should sequentially query all devices. In that regard I did not understand what "rewire Rx before Tx" means? Could you please let me know more about that design?

GUI is not needed but why adding external SRAM or FLASH should be tricky with PIC32? I found also the description how to use  parallel master port (PMP) to add external memory: Page 71 of PIC32 Family Ref.Manual http://http://ww1.microchip.com/downloads/en/DeviceDoc/61128D.pdf

Regarding re-work, sounds like interesting project, to me at least.

Web platform / Add 4 serial RS-232 ports
Hello,

in my project Web Platform could be used to collect data from 4 RS-232 lines, max 400 messages per day. What would be the easiest way to add 4 serial ports to current design?

There are PIC32 with 6 UARTs. Would it be a big effort to redesign the current board to PIC32? How is about the reusability of existing code for PIC33 if I would start the project with PIC32?

Thanks and regards,
srdjan
