Hello @chrisX12
Thank you for trying out SimpleFOC.
These are the pins for the NUCLEO-F446RE board:
6 D13 PA5 SPI1_SCK
5 D12 PA6 SPI1_MISO
4 D11 PA7 TIM14_CH1 || SPI1_MOSI
3 D10 PB6 TIM4_CH1 || SPI1_CS
From your description, on a high level, it seems you are doing everything correctly.
However it’s impossible to tell without code, so it would be helpful if you post the code, in its entirety, to at least be able to help with any suggestions.
Also, please check this thread, it may help.
Cheers,
Valentine
