Error with intent use an analog input

Question

Hi everybodies...

I have a trouble when i do "make" to compile my code, the error that show me is the next: DeviceDriver.c:(.text+0xc4): undefined reference to `HAL_ADC_Init'
DeviceDriver.c:(.text+0xd4): undefined reference to `HAL_ADC_ConfigChannel'.
I want to controller a Gauge with an analog input, i achieved compile the code for use one analog input, for this i used the software MDK-ARM and when transfer the code to the DeviceDriver and compile it, the comand show the error previously mentioned. I think that the compiler don´t into the library stm32f4xx_hal_adc.h, and although i set the "include" of this library, the error show yet. If someone can i help me I would appreciate it very much.

P.D. Sorry for my english, i am not an expert.

Hello Jesus,

no worries, I am not a native English speaker as well :D

 

It sounds like a linker issue. Did you adapted the stm32f7xx_hal_conf.h for using the ADC Module?

Additionally you have to include the matching HAL ADC c file. The linker needs the stm32f7xx_hal_adc.c to find the body of the used ADC functions.

 

Let me know whether it works after you done this steps.

 

Kind regards

Thanks Tim for your answer, at first i think that i only needed to add the library in the head of the code of the file DeviceDriver with #include "stm32f4xx_hal_adc.h" but it did not recognized the library then when i compiled all codes with "make" i saw that it was compiling some libraries of the folder hal driver but the library of adc previosly mentioned was not compiled, and after i search how modify the file "make" and add this library it was when the error disappear.
