Initial Configuration Sequence of STM32CubeMx and DMA Transfer Issues

Many STM32 developers often configure and generate initialization code based on the HAL library using STM32CubeMx. When it comes to DMA functionality, they find that it is ineffective, but cannot seem to identify the cause from the configuration operations and the code itself. This situation can often be quite frustrating. For example, someone reported that … Read more
