HELP me!
when i transfer only 14 32 bits data from ADC result FIFO to RAM, i found that 4 us will be cost. i want to know why so much time will be cost? one thing must be know, i used DMA to do that! see bellow:
MCU:5744P.
it is better that give me some document to specify the ADC result FIFO mechanism. thanks very much.
Hi,
I have created the example for ADC triggering DMA here:
https://community.nxp.com/docs/DOC-334154
How do you measure the DMA transfer time?

can some one help me?
