PWM Pins for RGB Led Strip #32

Closed Bubolz closed 4 years ago

Bubolz commented 4 years ago

I need to implement LED lighting using an analog RGB LED module, but only has 2 pins with free PWM for servos ... what other PWM-capable pins could I use?

Thanks!

makerbase-mks commented 4 years ago

Hi! I want to know, do you use EXP1?

Bubolz commented 4 years ago

Yes I will use LCD MKS Mini, but I will only use one hotend. Could I use the two servo pins (P1.23 and P2.0) and the HE1 pin (P2.6)?

makerbase-mks commented 4 years ago

of course! Yes you can use it.

Bubolz commented 4 years ago

Is there any more PWM pins on the limit switches that can be used? maybe in X +?

makerbase-mks commented 4 years ago

No, because limit switch has pullup resistor, but you can use LED1-LED4 pin image image

Bubolz commented 4 years ago

Right! Thanks for the quick response.

I need a pwm that already has a pin for connection. On some machines I’ll use touch LCDs so I’ll have EXP1 and EXP2 free, previously you suggested using EXP, what are the available free pwm pins?

EXP
