ESP32 and servo controller/ ninja failed with exit code 1

[BenR]

Hi Dirk,

Via C code using the servo controller component might be possible yes.

Try this function out.

FC_CAL_PWM_ChangeFrequency_1(100);

Where _1 is channel 1 and 100 is 100Hz duty.

....mh OK!! Putting that statement in a C Box will come back with a compiler error. It will not compile.

I assume the ESP32 C Box code is may differnt.

Hi Ben,

additional feedback. I just tried to open up a second servo controller in order to get at least 16 servo channels.
Then you get a compiler error again.

So is the limit 8 channels??

Hello Ben,

I have tested the servo controller further on.

If I assign two servos compiles perfectly like with one servo

If I assign 3 servo channels in the servo controller, complier quits with a error.

Hi Dirk,

The servo count is limited to 8 channels at the moment but in theory we could get this up to 12 on the ESP32 hardware. Let me know if this would be useful.

I tried to replicate the problem with 3 channels but it compiled correctly for me. Please can you attach the msg.txt file from the failed compilation and I'll have a look at what caused your error.

Adding the C code to set the freuency to 100Hz also worked ok for me. I've attached your current program with the c code in place to make channel 1 100Hz. Note that channels 1 and 2 share a timer and hence will probably always run at the same rate. Same goes for channels 2 and 3 etc.

Hi Ben,

attached the message file from compiler:

Yes 12 Servo channel would be perfect and great.

I`ll check your modified file. I´ll come back with a feedback.

Hi Ben,

your modified FC9 file with the 100Hz C-Box comes with a compiler error too at my installation.

Very strange that it runs at your side. May some wrong compiler settings at my installation??

Hello Ben,

Hello Matrix Team,

with the latest FC9 Update from today it now compiles with more then 2 servos assigned in the controller.

The C-code for different frame rates compiles OK too.

Many thanks!!

Hello Ben,

today I like to come back the the possibilty of 12 Servos outputs with ESP32. Do you have any news on this topic.
