Hi,
My ST32F103ZE needs to send and receive a serial bitstream to control some led display. I wrote a driver that simply controls a single GPIO port.
My question is: can I use the DMA controller in the ARM uC combined with some peripheral that will do the job for me?
(For example: I allready managed to use a USART with DMA).
Thanks
Henk
Some processors allows the SPI devices to be used with DMA. SPI can sometimes be nice for sending random bit streams at high speed.
This entirely depends on the particular capabilities of the specific chip - it is not a generic "ARM uC" question, and it has nothing whatsoever to do with Keil!
The specific Datasheet will answer the question...
