Hi All,
I want to generate digital clock/waveform at non timer pin STM32F4219igtb, let say using pin PORTD.5 and synchronize with several GPIOs using DMA. the purposed to drive the multiple HUB75 port.
Currently i'm succeed to drive the clock pin using timer pin, however the PCB and electronic schematic from wholesale controller not using timer pin. any body can help, very appreciate.
Thanks
Emha.
