I just finished a product design. In the design, the measured data needs to be uploaded to the PC via USB. I used the simplest method: "Serial Port convert to USB" and one IC can do it. The product ha...
Can anyone help me calculate the resistor values of this circuit diagram? http://s3.photo.qq.com/567172606/94699521 (Sorry, I don't know how to post pictures.) The transistor is 9014, the thyristor is...
Power supply is often the most easily overlooked link in the circuit design process. In fact, as an excellent design, power supply design should be very important, which greatly affects the performanc...
Has anyone used Bosch's PM sensor?
It's Bosch's carbon smoke sensor. There is no communication protocol when I bought it. I'm begging (helpless) for the communication protocol......
1. In terms of local service, TI is actually a local company. From samples, services, ordering, speed and good service, I am afraid it is faster than many domestic chip manufacturers and suppliers. Th...
When you touch the surface of the power module, it feels hot. Is the module broken? Wait a minute, it is a little hot just because it is working hard. But high temperature has a great impact on the re...
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]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[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]
Vertical cavity surface emitting lasers (VCSELs) are gradually replacing traditional edge emitting lasers, especially in low bandwidth and short-distance communication systems where cost factors ar...[Details]

This system is a simulation system of indoor air-conditioning temperature/humidity control system. The data acquisition and control center collects temperature/humidity...[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]
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]
This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
