I am fairly new to stm32 boards and used the cubeMX program to speed up development for a project I am working on. However, I have found that when sending messages with UART it takes 50ms for each transmit. That seems very slow. Is there a good way to start writing an alternative UART driver for the STMF0RB72T6 or a good open source library I could be directed to? I appreciate any help!
