I'm ashamed to say that I didn't understand the user manual very well. Although my settings can use AD sampling, I don't know how the specific sampling frequency is calculated....
We all know that X86 laptops have the technology to dynamically adjust the main frequency, so how can we achieve this on ARM? The best answer of the day will be awarded with 200 ChipCoins [[i] This po...
[table=98%,rgb(239, 245, 249)] [tr][td]Hi everyone, I use LPC1768 SSP0 again, configured as SPI, and found that the voltage waveform of MOSI MISO is not high or low level. As shown in the figure below...

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]
In order to highlight the concept of "energy saving and environmental protection" of intelligent buildings, solar street lights are designed for intelligent communities. The inclination and capacit...[Details]
1 Introduction
Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
