Hello everyone, I have a difficult problem and would like to ask for help from experts. I use the external interrupt EINT1 of the S3C6410 development board. In the driver, I use KernelIoControl(IOCTL_...
Everyone, I have been an electronic engineer for more than ten years. I am not very successful. Looking around, I don’t see many people who are very successful! Looking back on my career as an enginee...
Last time, I succeeded with interrupts, but this time I succeeded with reading the level. Last time I thought interrupts were the best, but this time I think level is better, because after all, there ...
During debugging, I found that sometimes the system cannot start because the STM32 is not reset, including using the STM32's own reset circuit and an external reset chip. Logically, this problem shoul...

All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
The data collector of the automatic weather station is generally designed based on a single-chip microcomputer or a PC/104 bus controller. It has the characteristics of good compatibility with PC, low...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
introduction
MAX6636 is a multi-channel precision temperature monitor that can not only monitor local temperature, but also connect up to 6 diodes externally. Each channel has a programmable...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
This article will introduce a design method for a distributed control system used in a tracking car, which can perform distributed control of motor modules, sensor modules, and lighting control mod...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
