Keil project not updated, I have no way to verify it.
Note, mw.c, drv_pwm.c and drv_system.c contain code for too many topics.
Later commits will relocate the code as appropriate.
Not even looked at utils yet. 'Utils' is a bad naming practice and is a
synonym for 'too lazy to find the right file/name'.
PWM6+7/TIM3_CH3+4/PB0+PB1
Update software serial to monitor serial pins for signal changes instead
of periodically sampling pin signals.
When reading the data the timer used is syncronized to the falling edge
of the start bit which allows for better syncronisation at higher
speeds. The code has been tested OK from 1200 baud to 19200. 38400
baud was tested and partially usable but has been disabled because there
are too many transmit and receive errors, especially when transmitting
and receiving at the same time.
Due to the way a single timer is used for transmitting and receiving, if
data comes in while transmitting the system may incorrectly transmit a
short or long bit. However at 19200 and below this didn't cause a
problem in the limited testing I performed.
set motor_pwm_rate to some value > 500 (1000, 8000, 16000 etc works on my scope).
then the motor output can be used to directly drive brushed motor fets.
PWM is rescaled to 0-base in brushed mode, so all same values of min/maxthrottle apply.
