I want to know how does eDMA call the callback function ...Is it calling by hardware? Can I send data by no callback function?
Solved! Go to Solution.
eDMA itself does not call any callback function. The callback function call is caused by the LPUART hardware interrupt. You have to disable the LPUART interrupts to never call the callback function.
