preface You can't play electronics without an oscilloscope, and you can't go whoring with a school oscilloscope after graduation. As the saying goes: no conditions create conditions. If there is no oscilloscope, create an oscilloscope. It sounds tall, but it's not difficult. There are many open source oscilloscopes on the Internet, the m ...

summary The title of all the work to be done in this paper basically includes reading the temperature value of the temperature sensor, and then printing it to the serial assistant through the serial port; A lot of bloggers' great God's tutorial I always follow the steps to make the program do not report errors and detect the sensor's condition ...

STM32 memory structure 1. Key points 1.1 two storage types: RAM and Flash Ram is readable and writable. On the memory structure of STM32, RAM address segment distribution [0x2000_0000, 0x2000_0000 + RAM size) Flash is read-only. On the memory structure of STM32, the flash address field [0x0800_0000, 0x2000_0000) 1.2 six types of stored d ...

preface 1: Driver reference from https://blog.csdn.net/BearPi/article/details/104311705.: 2: This is one of my records. I don't realize many functions. I just move a piece of video memory opened up in memory to the screen by DMA. 3: I didn't do anything during DMA handling, just gave him a delay to finish. In practical application, the semapho ...

The notes of the article are from the video of the Automation Association of Jiangke University I Interrupt system Interrupt: during the operation of the main program, a specific interrupt trigger condition occurs, causing the CPU to suspend the currently running program and process the interrupt program. After completion, it returns to the o ...

Data frame description STM32 data register is usartx - > Dr register It can be seen that only [8:0] bits of the DR register can be used, and the 8th bit is used for parity, that is, the DR register can only accept 8 bits, i.e. 1 byte of data at a time. An inappropriate analogy For example, a basket (DR register) can only hold 8 (bit) items, ...

A junior partner of SCM asked me to recommend C language books. Because the basis of C language is relatively poor, I want to learn C language again and learn SCM again. I had this idea when I first learned SCM before. In fact, C language can be learned while learning MCU. In some routines of learning MCU, if you encounter C language knowledg ...

stay C++ In, there is a special member function with the same name as the class name and no return value. It does not need to be explicitly called by the user (nor can the user), but is automatically executed when the object is created. This special member function is the Constructor.
