On microcontroller systems like the STM32, interrupts ... in the Cortex-M4. These interrupt channels all have a specific purpose, as defined in the vector table (e.g. RM0090, Table 62), which ...

This is something that we see a lot across STM32 peripherals, not just for USARTs, but also for timers ... way to use a UART. In upcoming articles we will look at adding interrupts, DMA transfers ...
