1. Introduction JMDM-WX32MB is a multifunctional industrial-grade high-reliability IO controller independently developed by Shenzhen Jingmin Digital Machine Co., Ltd. that supports wireless control, i...
I use an AVR microcontroller to implement SPI communication. I use two chips to communicate, one is a host and the other is a slave. However, the SPI protocol does not have a flow control setting. Whe...
First, use C809 to make an open-loop PWM controller: Refer tofor the configuration process: void TAU0_ini(void) { TMMK00=1; /*enable TAU channel0 interrupt*/ TMMK01=1; /*enable TAU channel1 interrupt*...
Regarding the relationship between capacitance and frequency, coupling capacitors, filter capacitors, bypass capacitors, etc. are often used in amplifier circuits. I want to know the relationship betw...
I have a question for you. When there is no program in the FLASH on my S3C44B0 board, or I have directly erased it, can I use AXD to simulate and debug it in SDRAM through the JTAG port? Some people s...
In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer

The stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. In the case of non...[Details]
Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
VP2188 is a color STN LCD module produced by Jingdian Pengyuan. This module is a dot matrix transmissive color STN display screen with a color scale of 65 k colors and white LED backlight. Its core...[Details]
Among the many members of the single-chip microcomputer family, the MCS-51 series of single-chip microcomputers has occupied the main market of industrial measurement and control and automation eng...[Details]
From the previous section, we have learned that the timer/counter in the microcontroller can have multiple uses, so how can I make them work for the purpose I need? This requires setting the timer/...[Details]
OC faults may be the most frequent and the most frequent of all faults in the inverter. They alarm during the startup process, during the shutdown process, during operation, and even when powered o...[Details]
Preface
In recent years, white light LEDs have gradually replaced incandescent bulbs and fluorescent lamps because they have unparalleled advantages over traditional light sources in terms...[Details]
Only a small number of LED manufacturers can produce high-quality LEDs. For applications that are only used for simple indication, low-quality LEDs are sufficient. However, high-quality LEDs must...[Details]
