nrf51422a led intensity control

[Mohamed O.Abouzeid]

I wonder if I can ask about the leds intensity control:

I need to control the led intensity without the PWM because I'm using the softdevice & PWM didn't work with it, I'm thinking of applying a waveform of zeros& ones to led & the resultant intensity depends on how much ones in the waveform I need another method as the previous one didn't work

Hi,

have you tried PWM (app_pwm) from SDK? It's working fine with SoftDevice. Another thing that you could try is to use app_timer to create software-controlled low power, low frequency PWM. It's not precise because of other interrupts (mainly softdevice) but might be good enough for LED intensity changing. BTW you will find such module in upcoming SDK.

where to find the app_pwm ? ? I tried the app_pwm from SDK and it didn't work with softdevice is there a method to make it work with softdevice
