How to implement timer interrupt on MKR 1010? - Arduino Forum
WEBSep 9, 2019 · Here's some example code that sets up the SAMD21's TC4 timer in match frequency (MFRQ) mode and calls the interrupt service routine every 5ms: PORT->Group[PORTA].DIRSET.reg = PORT_PA21; // Set D7 as a digital output. GCLK->CLKCTRL.reg = GCLK_CLKCTRL_CLKEN | // Enable GCLK0 for TC4 and TC5.
Timer1 - how do you set a 1 minute timer? - Arduino Forum
WEBAug 20, 2016 · RESOLUTION is set to 65536 because Timer1 is a 16bit timer. cycles = (16,000,000 / 2,000,000) * 60,000,000 = 480,000,000 So, cycles is NOT less than RESOLUTION - 1, therefore it was more than maximum. This code sets the prescaler to 1024, as slow as you can get. A prescaler of 1024 allows for a maximum time of …
