33664 Implementation with Arduino

Kyle4 — Thu, 14 Dec 2023 07:01:12 GMT

I am using an Arduino nano esp32 as a microcontroller for my 33664. The schematic is as follows:

I typically use the SPI.h library for SPI communication with arduino devices, but obviously I cannot use that library in this instance as the implementation here is DUAL-SPI rather than regular SPI. I have looked into the SPI.h library itself to understand the functions so that I can write a custom driver but I am lost as to how I can implement my own functions properly. This is the implementation which I am trying to achieve:

I've read through the lengthy documentation for both of these chips but I am still empty handed as far as code implementation for the micro-controller. I would greatly appreciate any advice / insight to my issue.

Thank you

We have software for reference you can download:

Thank you for the response. Do you have any software references for the microcontroller implementation? Since the MCU connects to the 33664 through dual-SPI, which connects to the 33771 through TPL, I need to know what SPI messages to send and expect back from the 33664/33771.
