Access GPIOHS through DMA
max last edited by
I want to access gpiohs through DMA, but the document are not that clear how to do it.
And how fast is the gpiohs ? How about get 16bit data from gpiohs by DMA at 50MHz ?
The gpiohs have no DMA handshake function, so it can't use through DMA. But you can use OSPI instead, it have 8 pins and act like GPIO.
