51 Microcontroller Naming Rules A simple example 89C51: 8 represents an 8-bit microcontroller; 9 represents flash memory, where 0 indicates no ROM, 7 indicates EEPROM memory, and C indicates CMOS technology, while S indicates ISP programming method; 1 represents the internal program memory capacity, with the size corresponding to this digit * 4KB. 89C52: 8KB … Read more
Working Principle and Usage of 51 Microcontroller Timer TMOD: Controls the working mode of the timer. 8 bits, the high four bits control T1, and the low four bits control T0. There are four working modes for the timer; TMOD = 0x00 (Mode 0), TMOD = 0x01 (Mode 1), TMOD = 0x02 (Mode 2), TMOD … Read more
Recently, I read some posts about RTC calibration and found that many people have doubts. Coincidentally, I also implemented RTC calibration in STM32 recently. Here are some insights. While this may seem trivial to experienced users, it can be beneficial for beginners. One of the core implementations of RTC calibration is the function void BKP_SetRTCCalibrationValue … Read more
Introduction The car parking lock system based on RFID video technology consists of a core circuit board with STM32F103C8T6 microcontroller, an LCD1602 liquid crystal display circuit, an RFID module circuit, a button circuit, and a relay circuit. The relay simulates the car parking entrance lock switch, normally closed to prevent other vehicles from entering. If … Read more
Ways of Communication Between Devices Generally, the communication methods between devices can be divided into parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the direction of data transmission, it can be divided into: Simplex: Data transmission only supports … Read more
Waking up in the morning and smiling at the sky, after smiling I go back to sleep, After waking up I smile at the sky again, then sleep for a bit longer. When I get up in the morning, feeling refreshed all over, I know I’ve overslept again. Life is… Those nights when I want … Read more
