5643L,PMSM,PWM-CTU-ADC

[chenxiubo]

Hi,

   My team is using 5643L to develop  PMSM  Project  for  E- car，and refer  AN4518.

The hardware used ADC0 :channel AN[0],AN[1],AN[3],AN[5],AN[8],AN[11],AN[12],also ADC1:channel AN[0],AN[1],AN[3],AN[5],AN[8].

Here phase currrent used ADC1:AN[0],AN[5],AN[8],the current needs to be measured accurately and in the right instant,others ADC

channel not very important.

In Cross Triggering Unit module ,I used  dual conversion mode ,in ADC module ,I configued  ADC0&ADC1 in CTU mode.

How can I write  CTU drive code and AD drive code?

Hi,

I can give you a demo example for the CTU usage, see attached file.

A document dealing with whole synchronization concept can be find on Community too; see

https://community.freescale.com/docs/DOC-102559.

Hope it helps.
