......@@ -247,10 +247,7 @@ Suitable pin groups for PWM function
- PWMC1_PWMH2(PA31,PD5), maybe? (PA31 collisions with SPI0, !! PD5 collison with GRX0-EMAC)
- PWMC1_PWMH3(PA8,PD7), (PA8 collisions with AFEC, )
Selected pins for PWMs:
- channel 0:
- PWMH0: PD20
- PWMH1:
Due to compatibility with different power drivers, routing both H and L channels is desired. Concerning PWM0 peripheral, all H and L have been routed (all outputs are complementary). Concerning PWM1, it's not possible to route H output for channel 2 together with HSMCI peripheral (SD card), so only 3 channels have complementary outputs. Overall, 7 complementary channels PWM0_CH0-3 and PWM1_CH0-1,3 are available. It should be possible for L output to act the same as H output (and vice versa).
#### Power considerations
The power connector has two positive voltage rails, one for power outputs for motors and the second for control logic (MCU etc..). The power board should include a step-down 5V converter which will power the MCU board. The MCU board should by default be powered by 5V (we want the MCU board to be also powered from USB source). The MCU board should include a step-down 3.3V converter for powering the ATSAMV71.
