I have to read SPI data from a MAX31855 chip which outputs 32 bits on each CS cycle.
Could we add a 32 bit data length to the SPI interface?
Thanks a lot
Alex

Only 8 and 16 bits are supported yet)

Anything new with this issue?
I would also like to use thermocouples with esp, I need to measure temperatures between +55C - +400C.

The SPI module was recently enhanced by
Extend SPI module API with improved transaction handling to support 1-32 bit data for spi.send(). More complex transactions with Command, Address and MOSI/MISO phases are possible now as well.
Code is only available from dev branch so far and still WIP, but you can have try with
NodeMCU custom builds.
