This library prints the registers for the Arduino Zero (and similar boards). It specifically is designed to print the values of the configuration register but not the status registers.
Intended Audience: advanced users who have already looked at the SAM D21 datasheet.
This will show the registers when the device boots:
#include <ZeroRegs.h>
void setup() {
SerialUSB.begin(9600);
while (! SerialUSB) {} // wait for serial monitor to attach
ZeroRegOptions opts = { SerialUSB, false };
printZeroRegs(opts);
}This will show the registers every time USB is connected:
#include <ZeroRegs.h>
bool serialShown = false;
void setup() {
SerialUSB.begin(9600);
}
void loop() {
if (SerialUSB) {
if (! serialShown) {
ZeroRegOptions opts = { SerialUSB, false };
printZeroRegs(opts);
serialShown = true;
}
} else {
serialShown = false;
}
