Generating Manchester Encoded bitstream from a GPIO STM32F4

[SPaud.1]

Hello,

I need to generate a Manchester Encoded bitstream from one of the GPIO of STM32F4 with a data rate higher than 1 Mbps. Is it possible to do so? If yes, how can I do so?

Use a TIM on APB2 to establish rate, use DMA2, and move a pattern buffer to &GPIOx->BSRR

Create the pattern buffer deep enough, and circular, interrupting on DMA HT, TC, so that you can output continuously while decimating interrupt loading.

I Will try it, thanks.

Hi, for now, I tried to transfer bits 0 and 1 to the ODR register of Port D via DMA2 Stream triggered with Timer. I am getting no response on pin PD0. Attached is the source code I have tried.
