https://devzone.nordicsemi.com/f/nordic-q-a/60397/nrf52832---timer0---gpioe--ppi-clock-is-inaccurateI have clock drift issue, should I calibrate anything? I test this simple code to get 1second or 100ms signal both of them are inaccurate. here is my code for 100ms; I tested it with a 16mhz timer clock but the result was similar.
