This form of interrupt-driven I/O is fine for moving small amounts of data but can produce high overhead when used for bulk data movement such as disk I/O. To solve this problem,direct memory access (DMA)is used. After setting up buffers, pointers, and counters for the I/O device, ...

However, to save power we must switch the application from constantly polling the DMA output to an interrupt-driven solution. The ideal solution is to allow our application to stop polling the UART RX DMA output location, and use an interrupt to wake our task and begin polling UART ...
I forgot to precise I'm using the LPC11U14, I haven't seen a DMA in the datasheet, there is one ? Or is it only in LPC17XX serie ? If you got any interrupt-driven SPI, I'd be glad to read some :)For now, i manage to get interrupts at the good moment, but not when in...
Implementation of Interrupt-driven Serial I/O Based On ARM Core MCU Without Nesting Through tailoring the scanf()/printf() function, a method is presented to implement serial I/O. It makes use of IRQ and self-founded FIFO queue to drive th... Q Wen,D Jiang,J Zhao - 《Microcomputer ...
