STM32F411-VET6 with SSD1322 compilation errors

[Andy11430]

Hello Guys,

 i want to use the Display SSD 1322 OLED with the STM32F411-VET6 Development Board but i cant use the example on github: https://github.com/wjklimek1/SSD1322_OLED_library it comes with many errors when i use the library for the STM32F411. Following error displays on CubeIDE "error: 'hspi5' undeclared (first use in this function)".

i have attached my project file for testing.

many thanks!

So you haven't defined the handle for your SPI interface?

Or, if you have defined one, you've given it a different name?

Declare the variable before you use it. You don't say which file has this error, but put this declaration before its use.

extern SPI_HandleTypeDef hspi5;

Hello,

First, you need to add a declaration of hspi5 in SSD1322_HW_Driver.c:  extern SPI_HandleTypeDef hspi5;

Second, I don't know why you have two initialization functions for the same peripherals in spi.c and uart.c (Ex: HAL_SPI_MspInit() declared twice).

These functions were already generated in main.c by CubeMx!

Attached your project on which I fixed the compilation error. You need to check again your peripherals configurations.
