Hi!

I've read the topic: how to use newsoftserial with max32.

On the UNO32, there're two hardware serial ports. I need a third one:

• harwdare serial for debugging,
• first NewSoftSerial for GPS
• second NewSoftSerial for LCD + touch

On Arduino, the solution is NewSoftSerial.

On my UNO32, the following code doesn't work

#include "WProgram.h"
#include "NewSoftSerial.h"

NewSoftSerial mySerial(2, 3);

void setup() {
  mySerial.begin(19200);
  mySerial.print("\n\n\n***\n");
}

void loop() { 
}

raises the error

/Users/~/Documents/Arduino/_Projets/libraries/NewSoftSerial/NewSoftSerial.cpp:37:27: fatal error: avr/interrupt.h: No such file or directory
compilation terminated.

How to proceed :?: Any alternative :?:

Thanks.

As the error indicates, you're trying to use low level AVR code on a PIC32 ... it will never work :) You could try porting the AVR code to the PIC32.

I'm afraid this is out of my reach :(

I'm not looking for a technical solution, but for a functional feature.

One solution could be an official port of avr low-level libraries, in order to provide a bigger compatibility with Arduino (as claimed).

Another solution could be a written from scarch new library for the UNO32.

NewSoftSerial would be very difficult to port as it uses lots of AVR assembly and clockspeed-specific timing tables. But try the SoftwareSerial library, that at least compiles, although I haven't tried it on UNO32.

Thanks davec :)

I did, but SoftwareSerial doesn't provide the flush and avaliable instructions I need.

Please note I'm not looking for a port of NewSoftSerial into chipKIT, but rather for a library that provides same functionalities.

Unfortunately, developing such a library on chipKIT is out of my reach :(

What value do you place on your time, avenue33?

The fastest/cheapest/easiest option might just be to put your Uno32 on the shelf for a while, and buy a Max32. It has four serial ports.
