this demo is based on the at-start board, in this demo, provides a description
|
|
|
|
of how to use a dma channel to transfer a halfword data buffer from embedded
|
|
|
|
sram memory to gpioc and gpioc0~gpioc15 output the data of data buffer. dma2
|
|
|
|
channel1 is configured to transfer the contents of a 16-halfword data buffer
|
|
|
|
stored in embedded sram memory to the gpioc. if transfer full data, the three
|
|
|
|
leds will turn on, and dma2 enabled the dmamux function. user can use logic
|
|
|
|
analyzer get waveform.
