undefined reference to `HAL_ADC_Init'

[msche.1]

I've been trying for hours to read an analog value from a pin and write it over UART with no success on my STM32MP1. I've assigned PF14 to ADC2_INN2 and set IN2 to "IN2 Differential", then I generate the code and when I try to build I get a bunch of errors with regards to HAL functions.

I have "#define HAL_ADC_MODULE_ENABLED" in my stm32mp1xx_hal_conf.h, which I thought would be what I needed.

Hello @msche.1​ ,

Thanks for your feedback,

Could you please share your .ioc file and specify the CubeMX version?

Thanks,

Sara.

Hello @msche.1​ ,

I generated a project using your ioc file and I didn't face any issue. There were no compilation error. I also tried to start a project from scratch with the same config and still, no error generated.

Could you please share your project to help you solve the issue?

Thanks,

Sara.

Strange, I imported my IOC and all my code from main.c and it's working now.

even you enable the HAL_ADC_MODULE_ENABLED into hal conf file, you should add $(DRIVER_DIR)/stm32f1xx_hal_adc.c \ in C_SOURCES into makefile to compile all adc HAL functions.
