The SPI communication configuration is all right, and there is no problem sending data. But the receiving block cannot receive data, and the data read is always 0x0000FFFF. Please give me some advice,...
I was debugging an SPI interface device, but I couldn't get it to work. Later, when I measured the pins, I found that there was crosstalk between adjacent pins. When the IO was set to 1, the voltage o...
