I want to receive data from the camera via UART.   To set the camera
I have  to send each other packages of about 5 bytes to uart use DMA .  while each packet sent . I receive confirmation from the uart data using  DMA..I change library lpc17xx.cmsis.driver.library \ uart_dma to do  this on LPCXpresso.
but the problem I can only send a single packet for the first  time and received data packets .I can not be sent next packet I try to  create a loop but can not be reset DMA after send packet the frirst time.
What is my problem?
is there a way to solve it?
Last question using DMA UART faster UART interrupt ?
