PWM configuration
To find appriopate device and channel find in the MCU datasheet table concerning "Alternate function AF0 to AF7" a text similar to TIM[X]_CH[Y], where: TIM[X] - is device, [Y] - describes used channel (indexed from 0), for example TIM2_CH1 is channel 0 in configuration structure (cc_chan - field), Port column in the table describes connected port. For Nucleo-U575ZI-Q this information is in the datasheet, Table 27, page 127.
