Can anyone provide a simple sketch to read and write a single byte to an external FRAM chip via SPI?
I’ve spent the last three days trying unsuccessfully.
Hi folks,
I’m really struggling with this.
I’ve tried every sample code I could find. I’ve tried different SPI modes and frequecies.
I’m monitoring the various SPI lines on an oscilloscope.
Chip select appears to be operating as expected (goes low and high).
MOSI - nothing changes.
MISO- nothing changes.
SCK- nothing changes.
I would really appreciate if anyone had working code to communicate with a FM25CL64B-G (Fram chip) from a Xiao RP2040 board.
Thanks in advance.
Paul
