 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

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 Edited 2024-11-01 05:55 by georgestheking |

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 Edited 2024-11-01 05:53 by matherp |

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 |
