6 Pwm with Timer1,2

[FormerMember]

Hi,

I have a problem with pwm,

I am using keil uvision 5.17, SDK 9.0.0, SD 130, nRF 51822.

I have programmed the code which can control servo motor(SG90) by smartphone.

The problem is I need to control 6 servo motor, it means that I need 6 PWM instance.

Technically, nRF 518222 only provide 4 PWM instance, and I programmed code already.

But 6 PWM can't,

Can Anyone give me an advice or example code? or tell me if it is possible at least?

As you have pointed out, the total number of PWM channels you can have with two hardware timers (Timer1 and Timer 2) is 4, since each PWM instance can have two output channels. The number of independent PWM instances depends on the number of hardware timers since each PWM instance allocates a timer instance.

So.. you want to say 6 PWM can't be controlled on nRF 51822 ?

Yes, that is correct, the maximum number of PWM channels is 4.
