/* Driving two DC motors
* -----------------------
*
* Custom timer originally intended to DC motor
* control purposes and made from two nested loops:
* - "scan cycle" is the main loop
* - "control cycle" is the internal loop
* Timing id adjusted by changing number of iterations en each loop
* and the internal delay of each control cycle iteration (tic). If scan
* cycle code takes significative time to jam current control cycle, this
* delay could be easily reduced or bypassed.
