The LCM202DDC I use can display a string of characters, but when displaying custom graphics, it is always garbled or not displayed. I read in the information that CGRAM is required to display custom g...
Both P89C51RC+ and P89C51RD+ are derivatives of the 8-bit 80C51 microcontroller. In addition to fully retaining the framework of the 80C51 instruction system and hardware structure, they have undergon...
I always receive inaccurate data when reading data from the serial port under WINCE6.0 on the s3c6410 board. When I debug, I see that the serial port buffer is not full every time, and there should be...
When dealing with practical application problems of RF systems, there are always some very difficult tasks. Matching the different impedances of the cascaded circuits is one of them. Generally, the ci...
Currently, an ATH10 temperature and humidity sensor is used to test the temperature and humidity of the board environment. A mechanical thermometer and humidity meter is used for comparison. The curre...
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]
Problems such as the depletion of natural resources, air pollution, traffic congestion, and rising fossil fuel prices have forced societies and individuals to seek alternative means of transportati...[Details]
Motors, especially those with brushes, generate a lot of noise. This noise must be dealt with if the appliance is to meet the requirements of EMC standards. The means to solve EMC are nothing more ...[Details]
Introduction
Today, as IC (integrated circuit) has developed to a super-large scale, IC design based on IP (Intellectual Property) cores and their reuse are important means to ensure the ef...[Details]
LED is the abbreviation of the English word. Its main meanings are: LED = Light Emitting Diode, a solid-state semiconductor device that can convert electrical energy into visible light. It can dire...[Details]
Zarlink Semiconductor has developed an ultra-low-power RF transceiver chip for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices. It has high data rates, low power c...[Details]
The power supply is the core component of a computer. Although it is not of high value, all computer components rely on the switching power adapter to provide energy, so the stability of a power su...[Details]
1. Advantages of CAN-bus in coal mine communication
Coal mine production is a field closely related to the national economy and people's livelihood. Among them, coal mine safety is undoubtedly ...[Details]
As we all know, the manufacturing of modern automobiles is divided into four major processes: stamping, welding, painting and assembly, and the powertrain constitutes five inseparable production pr...[Details]
Since the first rechargeable battery was invented in 1859, batteries have been developed for a century and a half. With the improvement of human science and technology and the advancement of manufa...[Details]
1. Overview
