HI,
We are Beijing SWRD Electric Industrial Co., Ltd. Our company recently in the use of DSP - F28066PZ encountered a problem: bother you give a solution:
The AD sampling problem:
1. The DSP AD clock frequency clock as the highest: using software trigger the AD, AD sampling out the value is with big fluctuation, there are about 20 ~ 30 value. But using hardware to trigger, AD sampling value is less fluctuation, about 6 ~ 7 value;
2. Use software to trigger AD, reducing AD clock frequency clock a half, AD sampling out the value with smaller fluctuation, about 6 ~ 7 value;
3. Use synchronization acquisition, result0 and result1 sampling out the value with big fluctuation (no matter to use which hardware channel by result0 and result1, the fluctuation is larger), about 20 ~ 30 value. But using sequential sampling does not exist the problem.
