I accidentally saw a very interesting game, and I want to play it too... The rules are as follows: the person on the first floor asks a question. Then the person on the second floor must answer truthf...
Has anyone made a virtual serial port with DX? I heard that it requires a 6T or 4T microcontroller. Are there any with the same pins as 89c51? Please recommend a few. Thanks....
Photovoltaic inverters are the core equipment of photovoltaic systems. Their main function is to convert the direct current generated by photovoltaic modules into alternating current that meets the...[Details]
The status of interrupts in developing embedded systems is absolutely unquestionable. In the era of C51 microcontrollers, there were only 5 interrupts, including 2 external interrupts, 2 timer/counte...[Details]
In the actual project development process, hardware circuits often need to be modified, and the modified parts need to modify the driver. Thinking about the coming and going of such requirements is t...[Details]
The program got stuck during LCD initialization. Through hardware debugging, it was found that it was stuck in the Delay_ms() function. Going to the definition, it was found to be a macro definition ...[Details]
The trade war between China and the United States has become the focus. The United States has begun to play the ban card against Chinese technology companies. The ZTE incident shows that if the ban...[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]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
Serial Port: 一. USART_ITConfig(USART1, USART_IT_TXE, ENABLE): As long as the transmit register is empty, there will always be an interrupt. Therefore, if you are not sending data, turn off the tran...[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]
STM32 uses FSMC to read and write CPLD programs. CPLD is hung on the address line and data line of STM32. CPLD is regarded as an off-chip RAM for reading and writing. On the board I made, CPLD is hun...[Details]
