Hello,
I want to know if it is possible to configure a button to act with different Detection delay.
In other words I want to have a single button to be able to trigger...
Do we have KiCad version of nRF51822 QFN48 reference design? We looking at open source toolkits, including Eclipse, so KiCad comes into picture.
Thank you in advance!
The test code:
int main(void)
{
sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, softdevice_assertion_handle);
temp_init();
unsigned int aaa...
