How to control 3 or more than 3 LEDs using PWM on nRF51 ?

[Brajesh]

Hi All,

I have query regarding PWM usage in nRF51-DK. I have a requirement to control 3 LEDs (brightness and power) simulatneously. I intend to use PWM for the same. But as i have use the default example given in SDK, only 2 LED's can be controlled at a time (with Softdevice). I see, with 3 timers, one timer used for Softdevice and 2 are free for PWM. Can anyone suggest me how can i control more LED's with PWM or may be share an example code of the same ?

any help or suggestion would be well appreciated, thanks.

The Low-power PWM library which was introduces in SDK version 10 allows any number of independent PWM instances. This library uses an application timer and is therefore not very accurate, but is well suited for controlling LEDs.
