hadc1.Init.Resolution = ADC_RESOLUTION_8B;

Can you change with 6B ?

AND

sConfig.SamplingTime = ADC_SAMPLETIME_15CYCLES;

Can you delete this code ?

the PWM output for servo motor doesnt work while the ADC working and i couldn't write the code for calling the values from memory.

im using two timer and 6 analog input (ADC) .

Have you try to connect multimeter to pwm signal ?

Is there voltage fall down or grow up ?
