When should stm32 install the operating system?

If you are talking about the operating system, it's okay. Generally, single-chip microcomputers are used in the field of industrial control and need to respond quickly to external events. Generally, real-time operating systems are installed. Common ones include VxWorks (for NASA's aerospace equipment) uClinux (in some routers), FreeRTOS, uC/OS, etc.

The working frequency of STM32 can be doubled to 72M, while the frequency of C51 single-chip microcomputer should generally not exceed 24M 2. The RAM, ROM and FLASH storage space of STM32 single-chip microcomputer is dozens of times larger than that of C51 single-chip microcomputer 3. Compared with 51 single-chip microcomputer, S The peripherals provided by the TM32F103 series are also richer, such as CAN interface, USB interface, etc.

In fact, as small as the previous 51 single-chip microcomputer, it can also use the operating system.

STM32 series LINUX can't run.. But it can run uClinux without MMU... You can also run a smaller uCOSii, etc.~~~ If you want to learn LINUX, you need ARM9 series or higher films.. Now MINTHE DEVELOPMENT BOARD I2440 IS VERY COST-EFFECTIVE. IF YOU WANT TO PLAY EMBEDDED LINUX, YOU CAN PLAY THIS BOARD.

How to systematically learn STM32

First, select the project button above the menu bar, and click new uVision Project in the pop-up right-click menu... The option of. You need to name the project you are about to create. It is better to create a new folder to save the project file.

It's not difficult. Read more materials. First, write a few applets with Hui, and then use c. Buy a development board, practice more on the development board in combination with routines, and then put forward requirements for yourself. Compose some applets in combination with the development board. It will be easy to experience. STM32 is a good single-chip microcomputer.It's best if you have learned single-chip microcomputers.

If it is a development board, you can see the materials of the development board. When you need to use some functions of STM32, but 51 can't, STM32 naturally doesn't need to learn. You will directly look for a certain aspect of how to use STM32. For example, use the network card of the spi protocol, use serial communication, use rtos, etc.

Embedded system stm32

It depends on where you apply it. Now many things are modules, so you don't need much digital and analog electrical knowledge. The conclusion is: If you just want to learn STM32, you don't need any knowledge of digital and analog electricity. You can buy a development board, and you don't need to worry about those circuits at all.

STM32, or ARM7 and Cortex-M series chips, generally known as microcontrollers, rarely run more complex operating systems. Generally, they only use on-chip resources to do some underlying development, and relatively have more hardware requirements.

It can be said that STM32 is the core of ARM, with strong performance and can run OS, while the single-chip microcomputer has poor performance and is not suitable for running OS, but it can run RTOS to some extent. It can be said that ARM is a single-chip microcomputer with strong performance, but it is habitually no longer thought of ARM as a single-chip microcomputer. .

When using the embedded operating system of CMSIS V1 interface, the following steps are required: First, select your MCU model and the corresponding compiler in the Cubemx software.When configuring hardware resources such as clock tree, GPIO, USART, etc., the corresponding configuration needs to be completed according to the requirements of the operating system.
