Hello together,

it seems to me that the servo controller component is not compatible with ESP32.

Compiling faild with the following message:

Hi Dirk,

Thanks for letting us know. I'll investigate and see if I can get this resolved for you.

very good!! Thanks in advance

Hello Dirk,

Sorry for the delay the Servo motor component should now be supported by the ESP32 hardware. The only thing currently not supoorted is the AutoMove functions. The SetPosition and MoveToPosition macros should work correctly.

Please let me know if you have any problems.

Many Thanks Ben,

I will check it out with in the next weeks

Hello,

Many thanks for letting me know. I have replicated the problem you're having and have fixed it in the latest component. The problem was caused by only having a single servo channel enabled and it seems I had only tested with all 8 enabled. It should work as expected for you now.

I would also move the SetPosition call from inside the loop, to just before the loop in your program as updating the position in such a tight loop might cause you problems.

Hi Ben,

many thanks for the super fast fix!! Works great.

Scope shot below:

Additional question!! Is there a way to edit the frame rate. Now it is fixed at 20ms (50Hz). Cool would be 15ms and 10ms (75Hz and 100Hz) too.

Hi Dirk,

Brilliant glad it's working for you the servo controller component is currently fixed to 50hz but the pwm component should allow you to easily do this.

[dvcam99]

Hi Ben,

what do you mean with pwm component in order to change the frame rate fromm 50 to 100Hz

Should I use the PWM component instead of the servo controller component?? Is this your suggestion??

May is it possible to change the frame rate via a C-code??
