Hi, I am having a hard time using MAX31855 thermocouple amplifier with Arduino Due for school project. I just need serial data outputs(temperatures) and it doesn't matter if I uses normal digital pins or SPI pins. Since I am an mechanical engineering student, I have limited experience with programming.
I know libraries of MAX31855 (https://github.com/adafruit/Adafruit-MAX31855-library
) are based on AVR like for Mega and Uno so they are not working with Due which uses ARM.
I have been trying to modify the following codes but all of them didn't work.
1. http://forum.arduino.cc//index.php?PHPS ... c=150629.0
This guy uses SD card and it doesn't shoots outputs.
2. http://forum.arduino.cc//index.php?PHPS ... c=150351.0
The first two codes look OK for me but it just shoots 0 after three loops. Also, the first output that he got (1000000010000000100000001) looks like digital output data which are not converted to decimal numbers.
The last code didn't work at all.
I know converting AVR based libraries to ARM based libraries is very challenging. Is there any way that I can run MAX31855 with Due?
