I want to send serial data in Manchester code using STM32H7. Could anyone please tell me the solution? Or if you know an IC part that can be converted to Manchester code externally, please introduce it.

Use the timer, modulating the output.

Perhaps clock patterns via SPI

Or drive patterns via TIM+DMA+GPIO

Could you tell me a little more about it?
