Arduino core for spi library

EvilRobotDan

Hi,
Is there any news on an Arduino core version of the spi library for IOT ?
My existing application uses AsyncWebServer websockets which would be a very convenient way to get the tracking data from the onboard ESP32 to Android phone which needs it, but requires Arduino Core.

A forum search located a post saying you had something, but inconvenient to use - i'd be happy to try that if possible as porting AsyncWebServer is a pretty unattractive option.

Thanks,
Dan

Hello EvilRobotDan ,
could you try using this library? On the backend it still uses ESP-IDF calls for SPI, so it's intended to be used with OAK-IOT device. You could also change SPI send and SPI receive callbacks to work with any other MCU.
Thanks, Erik

Hi erik ,

Apologies for the slow response, got sidetracked. I tried the linked library, but had a variety of mismatch problems with the adapted demo I had patched together.

However, once I shoved the existing (GitHub) library into my Arduino installation it basically compiled fine, needed current esp32 core version and some stuff moving around but was simple enough.

So, success, iot75 running standalone and passing tracking data to other esp32 and Android over wi-fi.

Thanks for assistance.

It's great that you got it working @EvilRobotDan, thanks for circling back on it!
