Capacitors are widely used in audio components, such as filtering, anti-cross-coupling, high-frequency compensation, DC feedback, etc. However, if we break them down by function, manufacturing materia...
The interactive interface of the industrial computer is relatively simple, so it can be optimized to use minigui or not use a third-party graphics library. It is OK if it can run on the Linux virtual ...
I read a lot of information about LM3S811 a few days ago and ran several programs. I feel that its programming can be divided into the following levels: 1: Assembly-level operation, directly using ass...
The school requires a 24-hour clock in the format of XX:XX (hour:minute). The program has been completed, but the light that should be off is actually slightly lit when displayed. For example, when it...

【JDPCB】Qisda is introducing smart factories in phases. Chairman Chen Qihong said yesterday (25th) that through high automation, order delivery can be accelerated. The current benefits have reached a...[Details]
In the project, CPLD is needed to complete part of the algorithm design. The parameters are given by AVR, so the communication between AVR and CPLD needs to be completed. Therefore, a test program is...[Details]
Site conditions: 1. AD acquisition, DMA transmission; AD is set to single-channel continuous mode, DMA is set to single-shot mode. The upper threshold of the AD analog watchdog setting is less than t...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
Each I/O port of the AVR microcontroller corresponds to three registers: DDRx, PORTx and PINx, where DDRx is the data direction, i.e. input or output; PORTx is the state of the internal pull-up r...[Details]
Recently, the "2018 Household Photovoltaic Development Seminar" was successfully held in Hangzhou, Zhejiang Province. Sungrow attended the conference as a special co-organizer and summarized the statu...[Details]
