When I was an engineer, I used many USB to serial data cables, and found that only this data cable could adapt to the ISP download of STC microcontrollers. At that time, I asked STC Shanghai Company (...
Please help me! This is the basic equivalent test circuit of ADC driver ADA4932-1. I simulated it in multism. The red waveform is the input signal and the other is the output waveform. The output wave...
The development of TI DSP is similar to the development of integrated circuits. New DSPs are all 3.3V, but many peripheral circuits are still 5V. Therefore, in DSP systems, there are often problems wi...
Does anyone understand how drivers, IO Ports, IRQs and hardware are connected? The relationship between hardware and IRQ can be set dynamically, which can only be done through IO Ports. However, IO Po...
I use TOPWIN to write programs. When I add the HEX file I wrote and look for the model next to it, I don't see the model I want, STC12C5A08S2. It only has four models, namely: STC89C58RD STC89LV58RD S...
October is Open Hardware Month!About OSHWAThe Open Source Hardware Association (OSHWA) seeks to foster technical knowledge and encourage research that is accessible, collaborative, and respectful of u...
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
As a leading company in automotive semiconductors, Freescale and Khronos Group have jointly launched an automotive multimedia embedded microprocessor i.MX35 with an integrated OpenVG hardware acceler...[Details]
1. What is PWM What is PWM? Professionally speaking, it is pulse width modulation. In layman's terms, it is the continuous output of high and low levels. For example, the microcontroller outputs...[Details]

It has been a long time since I updated my disassembly work. This time, I bring you the belated disassembly of the Honor V10 Premium Edition. Let's follow the mobile phone portable editor to learn...[Details]
In the design process of low-cost intelligent instruments, the priority is cost. As the core component, the single-chip microcomputer is usually a low-end 8-bit or 4-bit machine. As far as the curr...[Details]
Configuration: ATMega16L @3.3V @7.3728MHz 1602B LCD @5.0V @6 lines Compiler: WinAVR 20060125 I built a multi-purpose board myself, 1602 is powered by 5V, M16 is powered by 3.3V. In order to ...[Details]
As more and more mechanical systems are replaced by electronic systems, power consumption and how to monitor it becomes increasingly important. Accurately monitoring the power consumption of electric...[Details]
Munich/Colombia, November 17, 2017 - Rohde & Schwarz (hereinafter referred to as R&S), a global leading manufacturer of test and measurement, communications, broadcast and media equipment, announced ...[Details]
// There are 4 seven-segment LEDs in the circuit . With this program, the refresh period of each LED is 200/4=50 Hz . //Change the value of DispResult in real time in the program, and the disp...[Details]
The STM32 has rich serial port resources and powerful functions. The STM32F103C8T6 used in this project can provide up to 3 serial ports, with a fractional baud rate generator, support for synchronou...[Details]
In the previous articles, GPIO usage: Light up the LED!, only the output of the IO port was described, and no input was mentioned. Because I recommend using interrupts as input, it can greatly reduce...[Details]
Because I wrote an IAP upgrade program for stm32 before, I summarized the three main difficulties of IAP upgrade: 1. How to set the interrupt vector, that is, the redirection of the interrupt vector ...[Details]
In recent years, the need for energy conservation in household appliances has become increasingly urgent. This is evident in the fact that refrigerators alone consume more than 10% of household ele...[Details]
