Hi,

I’m pretty confused despite the fact that I’m a very experienced Visual Studio developer.

I was reading this example:

http://embeddedsystemengineering.blogspot.com/2015/06/stm32f4-discovery-tutorial-4-configure.html

So in a new project for the STM32F407G-DISC1 board I added these lines to the source:

#include <stm32f4xx.h>
#include <stm32f4xx_rcc.h>
#include <stm32f4xx_flash.h>

The project compiled fine.

Then I added this function call to the first line in main:

RCC_DeInit();

This compiled but didn’t build – I understand why that is.

So I then added the file

F:\Users\Hugh\AppData\Local\VisualGDB\EmbeddedBSPs\arm-eabi\com.sysprogs.arm.stm32\STM32F4xxxx\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_rcc.c

To the projects Source files\Device-specific files\LL solution folder – using Visual Studio, Add existing item etc.

Once I did that the project will not compile, for example:

Error ‘HSI_VALUE’ undeclared

Error ‘RCC_TypeDef {aka struct <anonymous>}’ has no member named ‘DCKCFGR’; did you mean ‘PLLCFGR’?

and so on, in fact a total of 32 errors and 42 warning are reported.

I simply have no idea what to do next, how do I identify what else needs to be added to the Include and Source folders in the project?

It seems that all I can do is trial and error, incrementally searching and stuff – very very laborious.

Is there no way to get from some function name (RCC_DeInit) and find what headers and source files one needs and in what order to include those headers?

I tried to find the header that defines RCC_DCKCFGR_PLLI2SDIVQ for example, because that is reported as undefined when stm32f4xx_rcc.c gets compiled, but I cannot, I used Notepad++ to search the folder tree – no match.

Thanks
