I am trying to follow and expand on the SPI tutorial.
First, I am trying to figure out what the GPIO pins map to. When I type in Cpu.Pin. , it gives me the option of NO chip select pin up to GPIO_Pin15. I have put in GPIO_Pin1, but do not have a scope to figure out which pin that is.
Also, I have implemented a ADT7311 temperature sensor and am confused as to reading data back.
In the tutorial, the following is used:
byte tx_data = new byte; byte rx_data = new byte; MySPI.WriteRead(tx_data, rx_data);
How would I look at the rx_data?
