       This afternoon, at the OPPO Future Technology Conference, OPPO launched a new mobile phone - the OPPO X 2021 roll-up screen concept phone. At a time when folding phones are seen as the future ...[Details]

The 51 microcontroller is a widely used embedded system chip with high cost performance and versatility. In practical applications, the 51 microcontroller often needs to exchange data with other peri...[Details]

System introduction and preparation 1. RTX51_Tiny needs to occupy timer 0, timer 0 interrupt and register group 0. User programs can no longer use these resources. 2. First, add the header...[Details]

At present, lighting equipment generally adopts two methods: traditional timing control and manual control. These two control methods are inefficient, unreliable, and waste energy. Some places use voi...[Details]

I had a low-power version done more than four years ago. The debugging was OK at that time and the program was basically ported over. This time I modified it again and got it done. I thought it wou...[Details]

In my memory of entering society, cars have always been closely related to fuel and have a natural connection with oil. It seems that I have never doubted the eternity of this connection. However, wh...[Details]

Preface: I have been studying 51 single-chip microcomputers for some time. Taking advantage of today's free time, I have summarized some important knowledge for review later. 1. The basic structure...[Details]

Han's Laser held the 34th meeting of the 6th Board of Directors and reviewed and approved the "Proposal on Authorizing the Company's Management to Initiate Preliminary Preparations for the Domestic L...[Details]

Cypress's CY8C21×34 programmable system-on-chip (PSoC) mixed-signal array has an I/O analog multiplexer. Since each pin can be used as an analog input, a single SoC can easily implement control appli...[Details]

Since voltage and current need to be collected to calculate power, impedance and other information, the synchronous rule mode of STM32 is very suitable for this scenario. There are a few points to no...[Details]

1. Introduction During the on-site testing of instrumentation equipment, the test data of production variables are of great significance to the production process, so the accuracy requirements for t...[Details]

The schematic diagram of the high-precision interval voltmeter is shown in Figure (a). The circuit uses an amplifier and some high-precision components, which greatly improves the performance of the i...[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/cou...[Details]

As intermediate frequencies (IFs) get higher and higher in the communications world, it becomes increasingly important to understand how input impedance varies with frequency. This article explains wh...[Details]

According to foreign media reports, a South Korean research team has developed a thermoelectric material that can be used in wearable devices such as smart clothing and can maintain stable thermal ...[Details]
