Hello,
I try to initialize my SPI3 on the STM32F401RE Nucleo Board. But as soon as I call my
Init_SPIMaster(); in the main, I get the error message, that there is an undefined reference to HAL_SPI_Init. The must be something wrong with my SPI_HandleTypeDef but thats the way I saw in several examples.
The error Message is:
