Hello!
I am having issues with two lines of code
enum mode_t {RELATIVE, ABSOLUTE};
mode_t theMode = RELATIVE;
These work on my arduino leonardo board but not XIAO ble SENSE board not running on the mbed plateform but non-embed. Does anyone have a work around?
Hi there,
I have lurked on the thread at Arduino forum,
2 things:
I still don’t get the serial prompt asking Absolute or Relative prompt in serial, but knowing the question and typing A or R does in fact work and switch modes on the fly!
Thank you very much for this awesome solution in nearly 1 shot! Would you mind directing me on how I can convert this to a button change and preferably as an interrupt?
-
Xiao uses the DO and D1 as possible strapping pins. so any hard ware connections should be verified they won’t cause BL mode and serial port issues.
-
I don’t see any delay that is required for you to see the prompt after reset.
It should be this,
ezButton someButton (3, INPUT_PULLUP);
void setup() {
Serial.begin(9600); // ADD THIS AND TRY AGAIN.
delay (2000);
Serial.println("Hello ezButton World!\n");
someButton.setDebounceTime(50);
}

FWIW , You can generate an Interrupt on receive character in serial port. So …FYI

Thank you! I wasn’t aware of d0 and d1 acted as such. I figured stay away from pin 6,7 Tx/rx?
The delay worked! How do you add interrupt on incoming serial or is that built in?
I realized the error with enum issue stated initially. It appears those variables being used so I just renamed them.
Thank you!!
Hi there,
it something like this,
void setup(){
Serial.begin(9600);
pinMode(7, INPUT); // Make pin 7 RXD an input
// attach our interrupt pin to it's ISR
attachInterrupt(0, recISR, CHANGE);
// we need to call this to enable interrupts
interrupts();
}
// The interrupt hardware calls this when we hit our left bumper
void recISR(){
// rec = 1;
Serial.println("interrupt!");
}
this is only one way , there are several.
BTW , the solution was what I posted not your own
post… LOL

basically it’s the pin changing from the data arriving the Isr sets a flag and the loop reads the port REC data.
You are awesome. Thank you for the code and explanation!
