Hi guys,
I still haven’t solved the problem yet, and have been googling the problem with the max31855 and other devices on the same SPI.
All show similar problems with clearly Mosi problems and hard CS pin select detection.
Still I was wondering if something like this could be solved by software?
I came accross: https://github.com/UnexpectedMaker/ReflowMaster/blob/master/Code/Reflow_Master/Reflow_Master.ino
He uses preprocessor statements and tells the void setup who’s first.
So two questions: is it in gerneral advisable to use for every SPI device a tristate buffer?
Second does it make any difference if preprocessing code is used instead of simple if statements?
Sorry to bother you with more trivial questions.
Best regards
Bastiaan
