DMA USART callback function
Hello,
Stm32 F401RE Hal Library 2016 Works.
Stm32 F401RE Hal Library 2017(last version) DOESNT Works.
For Test purpose only I use USART DMA Send function. Main.C is like that...
Also This StMicroelectrincs youtube vide work 2016 HAL Library but it doesnt work 2017 Hal Library. Video is very simple actually. I test it maybe 10 times. but 2017 Hal Library doesnt work.
