The full-bridge structure plays a wide role in circuit design. This paper introduces a design of isolated power supply based on full-bridge DC-DC. The half-bridge IGBT board mentioned in the paper has...
Hello fellow experts:My current system architecture is that the external signal is transmitted to the PC through the "signal interception card" to MATLAB for calculation and processing and then output...
I am using MSP430F135 to build a project, but XT2 is not used. How can I properly handle the XT2IN and XT2OUT pins?Can I connect XT2IN to ground and leave XT2OUT floating?...
[list] [*][b][size=14pt]I had a project developed before, which used USB2.0. I made a board, which did not require firmware development and had a speed of over 30MB/S;[/size][/b] [/list]...

1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
Unique device identifiers are suitable for: ● Used as a serial number (e.g. USB string serial number or other terminal applications) ● Use the unique ID as a security key when used in conjunction wit...[Details]
I have read the source code of mbed these days, and the interface encapsulation for upper-level application calls is quite good. The code quality is relatively high, the comments are also very detai...[Details]
1. Usage scenarios In the first case, when using a common STM32 delay function, similar to HAL_Delay(time), since this function uses a loop to judge and delay, when executing this function, the ent...[Details]
0. Preparation First use st-link to connect the stm32 core board and PC for burning St-link Stm32 3.3V 3.3V GND GND SWDIO PART SWCLK DCLK Then connect with USB serial port board to v...[Details]
Regarding the PHY construction of LWIP, the PHY chip used is LAN8720A, RMII mode. Regarding the hardware connection part, the Atomic board F407 is used, and the hardware connection is as follows: ...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
1. Basic Concepts of LCD/LCM The structure of Liquid Crystal Display (LCD) is to place liquid crystals between two parallel pieces of glass. There are many vertical and horizontal fine wires between...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
On April 18-19, 2018, at the "Second Distributed Photovoltaic Carnival" held in Hangzhou, Jinko Power and China New Energy Assets Investment, Financing and Trading Platform (hereinafter referred to as...[Details]
This routine is also a classic routine on the development board. I modified the framework of the program to make it more suitable for future calls. The specific 4*4 keyboard scanning principle is rel...[Details]
What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[Details]
