ADC_Reading same values
I have programmed STMG030k8T6 MCU in a prototype
Channels used ADC_IN_0 as T_sense ADC_IN_15 AS BattMon
if I am calling any one of the function I am getting exact values what i measure in hardware
But if i called them both only reading values from CH 0 please help me to sort it out stuck for a long in this
Note:When i used conversion with DMA ,also getting the same issues
Reading channel_0
reading channel_15
but when read both
Already I have tried maximum of suggestions by the people but still struggling to get the solution

if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK)
{

}
HAL_ADC_Start(&hadc1);
HAL_ADC_PollForConversion(&hadc1, 1000);
