Today's topic feels like writing a memoir of my technical growth. In 2011, I didn't understand TI at all. I just often used their digital chips in the digital circuit experiment class at school to bui...
The signal output by the microcontroller needs to be amplified with a triode. The amplified signal is used to drive a desk lamp. The signal frequency is 125KHz. The triode used is 2N3904. The circuit ...
One microcontroller sends, and the other receives. Now I have a problem. After each string is sent, the sending microcontroller has to delay for about 400us before it can continue to send the next str...
Hello everyone! We have designed an acquisition and storage module. This module is designed using STM32+128MByte flash, which means that the acquisition and storage parts are already completed, and th...

The future energy storage hotspot is not coal or iron ore, but lithium. This lightest metal in nature may be the heaviest resource in the future energy landscape. China launched an ambitious electr...[Details]
1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
Direct digital frequency synthesis (DDS) has fast frequency switching and modulation capabilities and is widely used. However, when low power consumption and low cost are the main considerations, D...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
