| Summary: | This article provides an example of pseudo-parallel execution of three tasks on an STM32F103 microcontroller without using an operating system. The processes are described, including flashing of the built-in LED, transmitting and receiving data via the serial interface USART1 and changing the frequency of flashing of the built-in LED by pressing the button with the processing of contact rattling. The software part is organized using finite automata, which makes it possible to achieve pseudo-multitasking in the system. The article discusses in detail the initialization of I/O ports, configuring the UART interface and timer, as well as working with interrupts and global variables. |
