SDADC sample number of MPC5775k

[junyishen]

We can set the number of sample(256,I set)in a chirp in the SPT module, and then we can set the number of chirp(128,I set) in a frame. This means that when SPT.GBL_STATUS.B.FRM_ACQ_DONE is set, we should adopt 256*128 data,  but only the actual 128*208 data, if I increase the value of sample, the effective numerical maximum of only 208.

What's even more puzzling is that I reduce the value of sample, the number of actual sampling points will also be reduced, not the value of sample I set, of course, the actual value has been a multiple of 8.

What's wrong with this? How do I fix it?

Hi,

ADAS peripherals are very specific and they are supported only on request.

Therefore I do not expect someone here on community will answer to your query.

If you wan to get in touch with experts you have to submit a ticket:
