The NTC on the expansion board is connected to the A0 interface of the development board, which corresponds to the PA3 pin, the ADC of the 8th channel.
This time we use the ADC_MultiChannelSingleConve...
First of all, I have to say that this board is very beautiful. Since there are relatively few external interfaces, and I am familiar with FPGA (ALTERA and XILINX) before, I didn't do any experiments a...
1. dBm dBm is a value that measures the absolute value of power, and the calculation formula is: 10lgP (power value/1mw). [Example 1] If the transmission power P is 1mw, it is 0dBm after conversion to...
1. I don't understand this point either. When SPIFFRX is initialized, bit12~8 (RXFFST) = 0, bit4~0 (RXFFIL) = 8. According to the documentation, a receive interrupt occurs when RXFFST >= RXFFIL, and d...
My graduation project is to design an aluminum can recycling device. I want to know what kind of sensor can identify and distinguish aluminum cans from tinplate cans? Different materials are detected ...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Today, with the increasing integration of functions, mobile phones can also be used as portable media players (PMP), digital cameras, handheld computers (PDAs), and even global positioning systems ...[Details]
Do you often have to add brake fluid to your car's brakes? The fact that you need to pump out the brake fluid to make sure there is no gas in the brake fluid line may not be done by the car owner h...[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]
For a long time, due to the limitation of hardware conditions, the display devices of traditional small handheld devices such as PDA are usually monochrome LCD, and the user interface is very simpl...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[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]

PROFIBUS is an international, open, and manufacturer-independent fieldbus standard. It is widely used in manufacturing automation, process industry automation, and automatio...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[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]
