Why did I forget about the GPIO MUX?anakyr wrote:I'm 100% sure that I have a 40MHz crystal. Check attachment too. I will try first to include SPI_DEVICE_NO_DUMMY in order to ignore this checking, as the error message in red is saying. If it doesn't work, I will go to the registers
You can route your SPI directly to pins without using the GPIO MUX matrix, so with it you can achieve higher speeds. I think all your answers are in fact in the red warning message.
The Expert programmer easily writes any code from scratch.
The Smart programmer uses his google/github powers first
