The OP
 

Can the STM32 DMA be set to an interrupt with any index? [Copy link]

For example, if the DMA length is set to 100, there will be a HalfCpltCallback interrupt when the default storage reaches 50, and a CpltCallback interrupt when the default storage reaches 100.

If the length remains unchanged, can we set a custom interrupt, such as generating an interrupt when the storage reaches 25?
