Hello,

 

I am working on internal ADC of BF506F, I manage it through ACM module.What i want to do is just activate the a internal ADC in order to convert Analog Voltage value from a light sensor and past it to a global variable for whole system process. I activated SPORT1 and DMA4 (default DMA for ACM) modules in order to get and store the ADC return value. I am able to view my desire Output value from the memory but the Output values are not reliable!

 

For Correct Result, This is what i want:

but sometime the system(DMA4) seem cannot synchronize with ADC, and these are the cases not desired:
