thank you soooo much for this comment!

Abdul Rehman Thanks Abdul

Hi, You are correct

Hi! Enjoy :)

Hi, You can use a Potentiometer (Variable resistor)

Hi mate, Thumb Joystick Analog Input (X and Y), Mentioned that at 00:30

What pins do you use on the board for x and y?

Will do :)

@@mutexembedded2206 :-D

When you are using hx7** you don't need to activate stm32 ADC. but you'll need configure two GPIO-s something like this github.com/freakone/HX711

Hi Rayon, For 12bits adc, Volts = (value/4095) * 3.3V

@@mutexembedded2206 thanks for your quick response..Do you have any tutorial on interfacing the TMP36 temperature sensor?

@@R_M_20246 I don't. Shouldn't be hard

Hi Sayed, Do you still encounter the problem? Should not matter, but the only difference is that the F072 has 1 ADC,but still 16 channels.

@@mutexembedded2206 hi dude, thanks for the response. Unfortunately yes. This is my code sConfig.Channel = ADC_CHANNEL_16; HAL_ADC_ConfigChannel(&hadc, &sConfig); HAL_ADC_Start(&hadc); if (HAL_ADC_PollForConversion(&hadc, 5) == HAL_OK){ V1 = HAL_ADC_GetValue(&hadc); } sConfig.Channel = ADC_CHANNEL_10; HAL_ADC_ConfigChannel(&hadc, &sConfig); HAL_ADC_Start(&hadc); if (HAL_ADC_PollForConversion(&hadc, 5) == HAL_OK){ V2 = HAL_ADC_GetValue(&hadc); } HAL_Delay(50);

@@mutexembedded2206 actually, at the beginning when I execute it, it works correctly, I have two different and correct data for both channels. But the second time, when I want to read the new data, both channels have the previous data which are actually the data of channel number 2. So for me, it means that it is still on channel 2 !!!! Is it clear? Did u get what I mean?

Hi Gautam, Could be channel number or GPIO setting of the other ADC input. There is a much easier way to do this too. You can to the sequencer and get two values from 2 different channels convert sequentially

@@mutexembedded2206 So I must use one adc channel for the x axis and another adc channel for the y axis? And then convert the values?

@@GD_902 yes. If you would look at my video on ADC Multi channel ADC

@@mutexembedded2206 Okay I will go through that tutorial. I'm going through your tutorials one by one and thank you for your prompt reply. I shall definitely follow up on this topic once I implement your suggestions. Best regards Gautam Dhargalkar

Enjoy
