Hi Idahowalker, I read all you wrote for the SPI ESP32 tutorial. For some reason I cannot get the simplest output from SPI to work.
In your tutorial you haven't given any working example of a simple application of your SPI method. Would you mind giving one? I just need to have at least a send message with the sclk kicking. Otherwise' it's pretty discouraging. I'm trying to get the ADS1256 ADC ful-duplex to work, so no having sclk is pretty discouraging.
In my case I'm using the HSPI. And already, your tip about the TMS and TDI was really useful (I knew I couldn't program it while the ADC plugged in, but I didn't know why.
So yeah, just a little working example in Arduino that sends a Byte, that would be really golden.
Right now I get a (1043031) spi_master: check_trans_valid(676): invalid dev handle
