I've  tried get a servo to with pca 685  16channel board I've wired it up to pi pico and raspberry pi and Esp32

Not sure what I'm doing wrong  I like using thonny not sure what libaries I need to install to get this working.

I couldn't show you any code as I'm using a servo of gpio2  pin  separate power.

I'm having difficulty controling speed start position wait then move to end position wait and then return to start.

I not using the pca9685 on this pi pico.

 

 

Thanks any help please

@videogame95 You are giving us nothing to work with. Choose one device, if it doesn't work, paste the code here between the <> and some sort of wiring diagram will help also.

First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

Well, there's your problem.

 

Anything seems possible when you don't know what you're talking about.
