This library enables you to use Interrupt from Hardware Timers on an nRF52-based board. These nRF52 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise than other software timers using millis() or micros(). Now supports `Sparkfun Pro nRF52840 Mini`

nrf52_timerinterrupt's Issues

fatal error: nrf_timer.h: No such file or directory

Cant compile the code that uses this library. I get the following error message:

.pio\libdeps\mers\NRF52_TimerInterrupt\src/NRF52TimerInterrupt.h:81:10: fatal error: nrf_timer.h: No such file or directory

I am using:

  • PlatformIO Core, v5.2.4
  • Platform: nordicnrf52 v9.1.0
  • Arduino Core for nRF52, default for Platformio

How can it be? Looking at SDK v17.1.0, nrf_timer.h seems to be an essential file for this lib

Can't compile in Arduino IDE with Feather Sense board

Describe the bug

Arduino IDE version: 1.8.15
Adafruit_nrf52 version: 0.24.0
Board: Adafruit Feather Sense nrf52840
OS: MacOS Big Sur v11.5

After compiling the TimerInterruptLEDDemo.ino, it gave the following error messages:
