Enquiry about multichannel ADC for STM32F051R8T6 Board

[ygjagtap]

i am facing issue in generating PWM using to ADC channel in STM32F051R8T6 board so i wanted to ask that does this particular board supports multichannel ADC

Hello @ygjagtap and welcome to the ST Community 😊. 

As mentioned in the RM0091 Part 13.3.6:

There are up to 19 multiplexed channels:
• 16 analog inputs from GPIO pins (ADC_INx)
• 3 internal analog inputs (temperature sensor, internal reference voltage, VBAT channel)
It is possible to convert a single channel or a sequence of channels.

The sequence of the channels to be converted can be programmed in the ADC_CHSELR
channel selection register: each analog input channel has a dedicated selection bit
(CHSELx).

Best Regards.

Thankyou so much for your confirmation.

Can you kindly help me in Decoding the problem I am facing to get output using below attached main.c file.

I have initialized 2 ADC Channels and connected 2 potentiometer to each ADC respectively. But while rotating the potentiometer of ADC_Channel_5 both the values of PWM frequency changes and the other ADC Channel is not working at all. But I wanted the output as when I rotate the potentiometer of a particular ADC Channel the frequency of that particular channel should only change. Kindly can you help me with resolving the following issue.
