nRF51822 DMA for UART

[bulbse]

From reading the product specification and the reference manual, it appears that there is no accessable DMA controller. and since there is no EASY DMA for uart, how would I go about using some form of dma for uart?

Hi Bulbse,

DMA would require support from hardware. UART DMA is not supported on the current version of the chip. So the short answer is No. But you can consider to use SPI slave instead.

I want DMA for UART, not spi. Its good to know. Thanks Hung.

@Hung, can I infer from your response that a nrf51 version with DMA for UART is in the work? ;)
