SPI interface on Waveshare ESP32-C6-WROOM-1

Projects General Guidance

I feel like I've read myself around in circles here. haha. I'm trying to figure out how to hook up SPI connection to the Waveshare ESP32-C6-WROOM-1 Module (MOSI, MISO, SCK and CS). I've mostly worked with the simple 2 Wire I2C connections in the past and can't seem to get a straight answer (maybe because there isn't one?). I've tried multiple different methods for detecting the SPI, including a couple of pieces of code, etc. I've read that I may have to define the connections myself, as well. Any help or references to something to read to get a better understanding would be much appreciated! I'm looking to hook up an AS3935 Lightening Detector module.

which Tools>Board do you select?

try running the Finding your ESP32 Board’s Default SPI Pins code from ESP32 SPI Communication: Set Pins, Multiple SPI Bus Interfaces, and Peripherals
if I select Tools>Board ESP32C6 Dev module my ESP32C6_Dev_Board displays

MOSI: 19
MISO: 20
SCK: 21
SS: 18
SDA: 23
SCL: 22

then try connecting your AS3935 to the default SPI pins

possibly try the as3935 library?

Running this: ESP32 SPI Communication: Set Pins, Multiple SPI Bus Interfaces, and Peripherals

I get pretty much nothing in the serial monitor.

Just this output: ESP-ROM:esp32c6-20220919

I'm on ESP32 version 3.1.1 in the IDE.

I find to get Serial Monitor output on my ESP32C6 under
Tools set USB CDC On Boot > Enabled

That did it! Thanks so much. Never had reason to change that with my S3s! Lol. Thanks guys.

does the AS3935 work OK?

Yes. It is reading out to the serial monitor correctly. Im going to play around with a couple of 70cm/2m radios and my HF rig to see if I may need to do some adjustments to sensitivity and all that, but main goal for today was getting it up and working with sample code. I do appreciate the assistance!
