I am using STM32L496 Nucleo-144 connecting SPI1 to external Adafruit MAX31865 PT100 temp sensor using breadboard with Saleae.
For some reason (I have no clue at all), I got nothing from Saleae.
One thing I kinda of curious is the the pinout. From UM1279 User manual, the pinout are
- SPI_SCK PA5
- SPI1_MISO PA6
- SPI1_MOSI PA7
- SPI1_CS PD14
While from Cube the SPI1_NSS is PA4.
I am assuming SPI1_CS and SPI1_NSS are the same (either Chip Select or Slave Select). Just not sure which one should I follow. I did try both, no luck at all.
Why I am not seeing anything from Saleae? I would think should be a very straight forward thing.
