Here is the full code with the Serial.write not in the ISR: #include <Arduino.h> #include <imxrt.h> #include <DMAChannel.h> #define BUFFER_SIZE 8192 #define SEND_SIZE BUFFER_SIZE*4 void xbar_connect(unsigned int input, unsigned int output)...

Hello, I am attempting to read parallel data on GPIO1 using DMA as fast as possible, and wanted to know if there is a way to set the output buffer to somehow be the USB FIFO buffer. My goal is to get continuous data from the GPIO register as fast...
