I can map TIM15_CH1N on pin PB15 as an output ,that works,but as soon as I start using SPI2 this pin seems like the pin is suddenly assigned to the SPI.
Now I will use the SPI2 as a slave ,so the MOSI function is an input (wich I will discard),so I see no reason why I cannot use this pin as an output for TIM15_CH1N.
I want to use SPI2 as slave ,transmit only and I want PB15 to be assigned to TIM15_CH1N
is there any way to do this?
