Hello
I use TMS570 ADC Timer sampling. HAL software setting i have problem.
I want to receive value accurate. now I have receive value fluctuation,that have little Zigzag. I dont know why.
1. Enable sampling capacitor discharge... this means what?,whether that can affect adc value.
2.hal setting have two cycle time.. How are they different.
Yes, please increase the sample time for each channel. The default setting is 2 ADCLK cycles, which is too short. The actual sampling time required depends on the external impedance connected to the channel being sampled. You can refer to this application note for more details about how much sampling time is required: 
For trial, configure something like 1us for the sampling time and check if the issue is still observed.
