[SOLVED] HW SPI on ESP32-WROVER

[espruino-discuss3]

Quick question; has anyone been able to use SPI2 (hardware SPI) to receive data on the Espressif ESP32-WROVER-B?

Follow up question; which pins did you use?

Thanks 🙂!

The reason I asked is because I had an issue with reading data using the HW SPI.

As suggested by @gfwilliams, I've tried flashing Espruino 2.06, and an issue seems to have been introduced between Espruino v2.06 and 2.08.

I've attached some screenshots where I use the ESP32-WROVER to read from a chip which is expected to respond with [0, 18]. Be aware that with v. 2.06 SPI1 seems to have been used where we'd use SPI2 today, thats why I'm using it in the examples on v. 2.06.

I post this just for reference, I'll open an GitHub issue.
