Hi,
I want to use servo on picomite.
I use the cytron maker board.
I understand that the syntax are :
PWM 6,50,chA,5+servo1*.25
PWM 6,50,chB,5+servo2*.25
PWM 7,50,chA,5+servo3*.25
PWM 7,50,chB,5+servo4*.25
I try also DutyA
But it does not work.
Best regards,
Georges

What specific version of the firmware are you using? Let me know and I'll post a version with a specific SERVO command for you to play with/test.

Hi,
I use version 5.08 on picomite RP2040.
Servo need a 1 ms to 2 ms pulse every 20 ms.
Thanks for your help,
Georges

Try this
PicoMite.zip
Set the pins you want as PWM outputs e.g.
SETPIN GPn,PWM
Then use the servo command
SERVO channel, posA [,posB]
posA and posB can be between -20.0 and 120.0%
Make sure you understand which pins are on which PWM channel (see manual) and note that you can omit posA or posB but not both and if you want just posB then include the extra comma
e.g.
SERVO channel,,posB
This functionality will be part of the 6.00.00 release when finalised

I always used pulse out gcb to control mini servo. not tried on mmbasic, never thought of pwm. 1.5ms is mid position 1ms left to 2 ms right every 20 ms
