I am currently trying to use FRDM33771BSPIEV to monitor 8 cell voltages. I have connected the hardware

according to the user manual and the 4 wire SPI connections have also been setup. Here SAMV71 is master and MC33771B is slave module.

 

1)How do I receive messages from MC33771B?

2)How do I program MC33771B i.e what instructions do I use?(some commands such as MEAS_STACK have been mentioned in the data sheet, do I use them?)

3) Are there any examples files to control MC33771B or to atleast retrieve data from MC33771B?

Hi,

we provide this SW package which includes generic driver suitable for any 32bit MCU with SPI module and example for S32K144 MCU:
