Setting custom ADC_SAMPLINGTIME

[jernejp21]

I have a question how to set a custom ADC_SAMPLINGTIME. In this example it says it can be set, but I'm unable to set it. It always goes to the default value.

I have tried the following with no results.

#include <Arduino.h>
#include "stm32yyxx_ll_adc.h"
#define ADC_SAMPLINGTIME 7

#define ADC_SAMPLINGTIME 7
#include <Arduino.h>
#include "stm32yyxx_ll_adc.h"

I managed to get it working.

I created a file build_opt.h and put -DADC_SAMPLINGTIME=7 into it. That solved the problem.
