Interrupts on STM32 MCUs come in two flavors: internal and external. Both types of interrupts use the same core peripheral in the Cortex-M core: the Nested Vectored Interrupt Controller , or NVIC.

One of the most basic and also most versatile communication interfaces on an MCU is the UART, or Universal Asynchronous Receiver/Transmitter. Usually found in the form of either a UART or USART, th… ...

Test equipment receives data over RS485 and loops back the same data to DUT - STM32 over RS485 interface. At DUT - STM32, the received data is compared with the transmitted data. Ethernet Test Task: ...
