Max31865 not responding on spi

harshareddy

Hello,
We are using MAX31865 interfacing with CC1310. We are getting all the signals(CS, MOSI,SCLK) correct but it is not responding anything when we read 0x03 register(it suppose to read default value 0xFF). Can you please tell us anything we are missing?

Regards,
Harsha

Normally a conflict with sd card which sets spi speed and mode. Try reducing spi speed in sdcard.cpp - latest update in dev has already reduced it from 50MHz to 4MHz.

Also did you mean MAX31865 which is not implemented or MAX31855 which is implemented or are they identical?
