I'm using the TWR-K60F120M board with uVision 5 and MQX 4.0.1
I'm trying to send some data over USB that I get from another board I'm talking to via SPI.
Both bits work individually but I've found that whenever I'm writing directly to the registers USB wont work.
I had the same problem when using the LEDS on the board so I just switched to using the MQX GPIO functions.
I have tried MQXs SPI driver and that doesn't seem to work properly as I mentioned in here MQX 4 SPI Problem TWR-K60F120M
So I'm wondering why can't I use the USB driver and write directly to the registers? Is there any way to do this?
