UHCI- Uart DMA

Postby eng.m_mahmoud » Mon Apr 27, 2020 8:53 pm

Hello Team Support and esp32 developers,

Can you provide me with a sample code or a driver library for using the UART for Tx and Rx over the DMA (uhci).!
The uhci driver is still not available in esp-idf, but I found before post about some one who had contact the support team for the uhci and sample code and they sent it to him which runs OK for him as he stated.
please, I need this uart dma library and sample code.

Thanks,

Hi, @eng.m_mahmoud
This is the UHCI example, but please know that this is just an example, it may be unstable. you can refer to it and rewrite your own driver
thanks !!
