Multichannel adc stm32f411ceu6

[Putras]

What is the correct way to implement multiple ADC channels? I have tried various tutorials on YouTube, but none of them work correctly. I am using two potentiometers. The ADC readings are random and cannot be controlled by the potentiometers. At one point, I managed to get it working, but only one potentiometer responded. The second potentiometer did not work, and the value of Channel 2 followed the value of Channel 1, even though Channel 2 should be controlled independently by the second potentiometer.

Can you try this ADC Tutorials? 

And see if this helps.

Terima kasih, itu berhasil untuk STM32F103C8T6, tetapi tidak berfungsi pada STM32F411CEU6. Konfigurasi dan kodenya mungkin sedikit berbeda.

You can try the same example on F411 and see if it works.

Hello ​@Putras 

Mybe this post can help you.

Thank you, that worked for the STM32F103C8T6, but it doesn't work on the STM32F411CEU6. The configuration and code may be slightly different.

Hello ​@Putras 

A single ADC can convert only one channel at a time.
To read two potentiometers, enable Scan Conversion Mode and set Number of Conversions = 2.
Assign each potentiometer to a different ADC channel and give each one its own rank.
If you need continuous updates, enable Continuous Conversion Mode.

Please You can refer to ST’s ADC_MultiChannelSingleConversion example.
It shows how the ADC scans multiple channels in sequence.
Then adapt the same configuration to your STM32F411CEU6 board.
