Microcontroller peripherals

The control is fully dedicated to the microcontroller which is suitable for managing PWM

generation, analog sensing, by means of ADC, and executing four independent current

loops through PI standard controllers.

TIMER1: advanced control timer (TIM1)

Figure 4 shows the TIM1 block diagram

TIM1 block diagram

The TIM1 is a 16-bit advanced control timer with many settings and features for industrial

and motor control applications including protection for fault management.

The main features are:

●

16-bit Up, Down, and Up/down counter with auto reload function

●

4 independent channels with several configurations (input capture, output compare,

edge or center aligned PWM, one pulse mode and complementary outputs)

●

Break input

●

Interrupt and trigger event

The current reading methodology used in this application needs a trigger event, generated

by the timer, in order to start the ADC.
