Hi there!
I have nRF51 DK (PCA10028).
I config GIPO as below:
nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(false);
err_code = nrf_drv_gpiote_out_init...
Hi, I am generating PWM waves using GPIOTE, PPI and Timer. (I cannot use the app_pwm library from SDK 10.0 because there is an intial delay of ~600usec for the PWM to get...
Hi,
I want to generate PWM pulses of width 14uSec(off time) and 42uSec(on time). Is it possible to achieve the above
