I've been very busy recently, busy with meetings. This is a very important industry meeting, of course it has nothing to do with microcontrollers, haha. Today I have time to post a well-tuned small pr...
Almost all the hardware uses the Battleship development board, STM32F103. I just saw someone making a mobile phone and MP4 there. I feel a little itchy, but the final exam is coming this week, and the...
This paper introduces an automatic charger circuit for mobile phones and electric bicycles. It eliminates the complex IC circuit and its peripheral circuits, and can also complete the function of auto...
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
introduction
Throughout the history of automotive lighting, power has always played an important role. Initially, cars only needed headlights to see the road in the dark. Later, other light so...[Details]
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]
Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[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]
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]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[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]
With the rapid development of intelligent control technology, computers and information technology, the trend of information appliances IA (Information Application), computers and communications integ...[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]
Digital array radar (DAR) uses digital beam forming (DBF) in both receiving and transmitting modes to achieve flexible distribution and reception of RF signal power in the airspace, obtain excellent t...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
TC9012F is a universal CMOS large-scale integrated circuit for infrared remote control signal transmission, suitable for remote control of TV, VTR, laser player and other equipment. In the market, ...[Details]
