FreeRTOS task management basics [For Learning and Practice]
The basics of task management using FreeRTOS are explained with concrete descriptions in actual programs while explaining the concepts of configuration, so you can immediately apply them to your practical programs. Although it is intended for learning, it is of course usable in practice. Table of contents1 Task priority and frequency of use2 Task switching […]
FreeRtos[for STM32 learning]
There are various RTOS for microcontrollers, but this site uses FreeRTOS for learning STM32 microcontrollers. We use the conventional type for learning STM32 microcontrollers, not the latest AMAZON type. Since it is for learning, we think it is better to start with something as simple as possible. Table of contents1 What is FreeRTOS?2 Task management […]

Independent Watchdog timer Execution Example of function: IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable); Execution Example of function: IWDG_SetPrescaler(IWDG_Prescaler_32); Execution Example of function: IWDG_SetReload(3000);
DMA (Direct Memory Access) [DMA details of STM32]
Although DMA is not an essential skill for beginners or novice users, it may be required in practice because DMA reduces the CPU load, allowing CPU capacity to be used for other processing and contributing to power savings. In this chapter, I explain how to use DMA to transfer multiple channels of data from an […]
Serial communication SPI[SPI details of STM32]
This section explains how to use the STM32's built-in peripheral SPI. In this chapter, reading and writing data to and from an SPI-specification EEPROM is explained as an example.
