Hello. I am currently working on implementing UART transmission using DMA (Direct Memory Access) mode. However, I've encountered challenges due to the scarcity of information available online regarding this topic. My main struggle lies in understanding where and how to define the interrupt callback function for DMA-based UART transmission. I've searched extensively, but I haven't found comprehensive resources or examples to guide me through this process. If anyone in the community has experience or knowledge in this area, I would greatly appreciate any assistance or guidance you could provide. Specifically, if you could share a screenshot or provide a link to code demonstrating the setup and usage of DMA for UART transmission, it would be incredibly helpful. Thank you in advance for your support. I'm looking forward to learning from your expertise and overcoming this hurdle together.
