AD converter

Some interesting characteristics of this microcontroller are highlighted here, like PWM

peripheral and ADC triggering functions conducting to a PI current regulation loop for every

channel.

Figure 5.

TIM1 and ADC triggering functions

In Figure 5 above, the ADC peripheral block diagram is shown. The main ADC features

used in this application are:

●

10-bit with 16 multiplexed channels

●

3.5 µs of conversion time @ 4 MHz

●

External trigger and timer trigger selection

●

End of conversion interrupt

The most important feature is the triggering function, forced by TIM1, used to enable the

conversion on some timer events (reset, enable, up/down, and count).
