how to connect to ESP32-C3
How do I Connect the CC1101 to the ESP32-C3
To setup the CC1101 I cannot use the setSpiPin() as this will be reset by the init()->setSpi(). And there the ESP32 settings are SCK_PIN = 18; MISO_PIN = 19; MOSI_PIN = 23; SS_PIN = 5; will be set. But that is not the setup for the ESP32C3 or ESP32S2 support for the gpio_iomux_out / gpio_iomux_in is also missing. Please advice how to connect the CC1101

if you run setspiPin before init then your setspi config will be used. init only loads the default values if you don't define setspiPin. in the code is a query whether setSpiPin was set. This prevents init from taking the default values. it will use your set pins. Regards
Hi do you know which pin can use for gdo2 currently I use pin 3 instead 4 but It doesnt work. I got shotcoming to get signal. Recently I vary the pin and it seem none of it can be use. (Or perhap I broke the chip). I am try Serial.prinln(digitalPinToInterrupt(A3)); the out put shows 3. It indicate this pin can be use for inteerupt am I right?
Feyhong Send me a Email (Fey [At] emsign [dot] nl) then i will send you what i have done, it is not fit to put on Github
You can put your code on github by folk this lib. Thank for your supporative action!
