1 Introduction Hi, everyone, this is senior Dan Cheng. Today I'd like to introduce you to a very, very cool single chip microcomputer project Infrared imager based on single chip microcomputer It can be used in curriculum design or graduation design Technical solutions Design help:<Q>746876041 2 project introduction Does the ...

Demo display and hardware construction - light This is a demo of operating the LED to make it flash. We will introduce the basic methods of operating the hardware through this demo. Let's see the final effect first: [external chain picture transfer failed. The source station may have anti-theft chain mechanism. It is recommended to save the p ...

Bootstrap   people who have experience in installing computer systems know the concept of BIOS. Little friends who have brushed Android phones have heard of Bootloader. What is the relationship between these concepts and mobile phone startup?   first of all, the operating system does not start directly when the computer or mobile ph ...

1, Basic knowledge of serial communication 1. Serial communication interface of STM32. UART: universal asynchronous transceiver. USART: universal synchronous asynchronous transceiver. High capacity STM32F10x series chips, including 3 USART s and 2 UART S. 2. Connection mode between communication pin RXD and TXD 3. Communication data flo ...

1, The external crystal oscillator failed to start, resulting in abnormal serial port baud rate Model: stm32f407 In the development process, due to the design problems of wiring and conditioning circuit, the external crystal oscillator will fail to start. In stm32, when the external crystal oscillator fails to start, the internal high-spee ...

File system size The reason why it is not 6M is that there are directory and file information allocation tables, which will also occupy space. RTC is required for returning real-time time Equipment information acquisition Call the functions of the file system layer from the file system application layer. f_getfree: get free space Path, ...

Chapter IV Section II Thinking: how to achieve the following functions? Serial port echoLED cycle flashing (1 second interval)Task 1 and task 2 will not interfere with each other interrupt When the system stops the currently running program and transfers to other services, it may be that the program has accepted a request higher than its o ...

1. Conceptual Relevance 1.RTC RTC, full name in English: Real-time clock, Chinese name: Real-time clock, refers to electronic equipment that can output real time like a clock. It is generally an integrated circuit, so it is also called a clock chip. Real-time clock chip is one of the most widely used consumer electronic products in dai ...
