Hi i encounter this error while compiling SPI1 at ST7735.h, i dont understand as this error 'SPI_HandleTypeDef' type was generated by .ioc in main.c already and i had call this statement in ST7735.h. Could anyone kindly help?

error: unknown type name 'SPI_HandleTypeDef'   --> in st7735.h 

// st7735.h
#define ST7735_SPI_PORT hspi1
extern SPI_HandleTypeDef ST7735_SPI_PORT;

Hello @StanCosgrove ,

Check the settings of "Include Paths" and make sure to define 'USE_HAL_DRIVER' within the project setting.

Yes, you'll need to pull in the top level HAL include files for those definitions to be brought in by the compiler.

ie #include "stm32f0xx_hal.h"

And stm32f0xx_hal_conf.h will need to have the SPI line uncommented.

/* #define HAL_SPI_MODULE_ENABLED */

There's also obviously a processing order, the definitions need to come in before the usage
