I have updated the code with the modifications I proposed before. Now I get a stable value but is very low. What I am doing is selecting different channels for each function or is it reading all the time the same channel?

| Apr 14, 2017 at 9:27 | comment | added | Marco | @ammar.cma because within those other ADC read functions I use the reference to put in scale the measured values before sending them through the UART. | |
| Apr 14, 2017 at 9:25 | comment | added | ammar.cma | Why are you passing a reference value to another read ADC function? | |
| Apr 14, 2017 at 9:25 | comment | added | ammar.cma | The best way to know that is if you debug the code line by line. | |

@ammar.cma whenever the code executes HAL_ADC_GetValue(&hadc); it should get the value, but how can I tell from which ADC channel it is taking it?

@ammar.cma, I'm passing uint16_t volt1 which is a reference value measured by volt1 = readv1();.

| Apr 14, 2017 at 9:14 | comment | added | ammar.cma | readv2(volt1)? You're passing what argument exactly? | |
| Apr 14, 2017 at 9:08 | comment | added | brhans | In your 1st code snippet, you're not actually performing an A2D conversion - so not reality surprising you're seeing the same value. The 2nd snippet looks like it would do the job. | |
