Servo class on STM32F407 DISCOVERY

[gr4viton]

I found the Servo class for pyboard
http://docs.micropython.org/en/latest/p ... Servo.html
and I want to have the same functionality on STM32F407DISC board.

As I found out its written in C and only for the pyboard. Or is it not?
I have already played with PWM and I think a sort of "standard" servo class should be written in python as abstract to use it on any board. Or is the class Servo usable on any board?

I got nothing after importing pyb.Servo
AttributeError: 'module' object has no attribute 'Servo'

Is it because I did not make the upy firmware with the macro:
#define MICROPY_HW_ENABLE_SERVO (1)
in
micropython/stmhal/boards/STM32F4DISC/mpconfigboard.h

As it throw an error on making:
:micropython/stmhal$ make BOARD=STM32F4DISC
...

Should I try to repair the error or should I write and contribute separate python Servo module?

The qstr generator occasionally has problems. When you run into issues like the above, I normally do a clean:

Code: Select all

make BOARD=STM32F4DISC clean

and then rebuild.

I was able to build the latest micropython setting #define MICROPY_HW_ENABLE_SERVO (1) and building.
