When I used ISP to download, the chip could not be erased. I used Zhifeng's software, and then bought a JTAGice downloader, but I couldn't burn it using AVRstudio....
In a DC power supply circuit, changes in load can cause power supply noise. For example, in a digital circuit, when the circuit switches from one state to another, a large peak current will be generat...
I have no idea at all. The limitation is that I have to use 51 series chips, and I only have AT89S52 on hand. If all the possibilities of displaying the pointer on half screen are stored in the on-chi...
I haven't posted for a few days, I've been doing other things :) 2010.5.14 Tested the PWM function, now I'm posting some pictures!! You can set the duty cycle and so on according to the relevant param...
This article of the rookie was originally posted on the blog for a few days. Today, I accidentally found that hellodsp reposted it. Thinking about it, I have been lurking here for two years, especiall...
I made a voltage follower using AD8011 (current feedback type). The voltage signal is a small sine wave. I hope it can have a good following effect within the bandwidth of 80MHz.
The circuit is solder...

Pure electric vehicles, structurally speaking, have components such as a power battery. In addition to the power battery, a small battery also powers some low-voltage electrical components and even...[Details]
With the advent of the electric car era, the number of pure electric vehicles has increased significantly, but many car owners do not know how to properly maintain pure electric vehicles. In additi...[Details]
The difference between a series inverter and a parallel inverter is that they use different oscillation circuits. A series inverter connects L, R, and C in series, while a parallel inverter connect...[Details]
With the growth of the Internet of Things (IoT), wearable, and portable devices, consumers are growing weary of cluttered cables and the need for frequent battery recharges. The benefits of wireles...[Details]
When we pick up an unfamiliar object, the first thing we want to know is what it actually does. A drive shaft, as the name suggests, is a shaft that transmits power. It's the transmission medium th...[Details]
As automotive technology develops at an ever-increasing pace, the performance requirements for automotive internal structures, components, and accessories are becoming increasingly demanding. The d...[Details]
ESD protection diodes are specialized for small-signal ESD protection or surge protection TVS arrays, often used for multi-circuit protection. Their small package size, low on-state voltage, high i...[Details]
