No communication between the stm32f103c8 program by Arduino IDE and external connections

[YBell.1]

Hey Everyone'

Am using Stm32f103c8 with Arduino IDE to read temperature from thermistor and Voltage from the lithium battery cell, connected to LCD. I noticed the values received on the LCD is not both from the thermistor and the battery, because whenever I removed both the thermistor and the Battery connections, still the LCD Keep showing the same values also whenever I hold the thermistor for some moment nothing change on the LCD screen values, its always keep showing the same result I cannot figure out where the problem is, please I need help. Thank you in advance

You'll need to debug the code.

Perhaps you have a teacher, colleague or supervisor who can go over the code/logic with you?

I asked a lot of my colleagues but Non-one has answered me and unfortunately, my teacher doesn't have time for me:loudly_crying_face:. But now I decided to use STM32cubeMX and Keil to program the controller. Am to measure temperature from 1 thermistor, Current from 4 lithium cells, and Voltage from 4 lithium Battery cells that are all 9 ADC channels. I configured 9 ADC channels of ADC1 I used (PollForConversion) but still, it doesn't work the LCD is totally Blanck nothing has displayed I don't know where the problem is again. using (PollForConversion) I tried single-channel ADC I measured temperature from thermistor this time it works perfectly but as I added. Now I wanted to try DMA with 9 ADC Multi Channels but I don't know how to set 9 ADC channels by using DMA. Please I need help here attached is the Keil file, my codes for 9 ADC channels using PollForConversion if there is any small correction that makes it to be work, you can guide me Please. Thanks in advance
