Learn the AVR microcontroller tutorial header file in ten days

I recently started to learn AVR microcontrollers. Since the 51 development board I bought before is compatible with AVR microcontrollers, there is no need for a development board. So I found a tutorial on the Internet called "Learn AVR Microcontrollers in Ten Days", which was also taught by someone from Guo Tianxiang's

51 MCU driver for proximity switch

Today I made a little thing: the digital tube displays the change value of the proximity switch. The proximity switch is connected to the microcontroller through external interrupt 0; the digital tube reading increases to 50 and then clears to zero; #include reg51.h // Reference the header file of the standard libra

Different Applications of MCS-51 Single Chip Microcomputer in Timing Interruption

The interrupt response delay time of the MCS-51 microcontroller depends on whether other interrupt service routines are in progress, or on what instruction is being executed. The interrupt response time in a single interrupt system is 3 to 8 machine cycles . Regardless of the cause of the error, their impact must

Tips for re-programming the OTP of Songhan MCU!

1. Problem: In my early work, I often encountered that when doing tests, if I just want to modify some short instructions or data, I have to replace a new chip and re-burn it before testing. This wastes time, consumes chips, and also consumes money. 2. Solution: Actually, OTP is not as "stubborn" as you think. As

Single pin on microcontroller to detect ambient light and control lighting

A previous design idea (Reference 1) used an LED as a transducer to measure ambient light intensity and provide illumination. This design idea uses the same principles, but only has an LED, two resistors, an IC, and a 0.1mF bypass capacitor. When the circuit is used to provide ambient light feedback, it does not requir
