It is probably that a PWM wave of a certain frequency is generated by the clock. Using FPGA can get a more perfect waveform, but if only a CLK wave is provided, F5529LP can do it completely. #includeu...
Device: S3C2440 development board Phenomenon: After restarting the device, it is easy to cause the PC to freeze, and the keyboard and mouse have no function. Operation: When the PC is communicating wi...
It seems a bit inappropriate to write about this topic on the first day of 2013, but I wrote it when I remembered it. Many new employees in the workplace should also have many dreams when they enter t...
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]
Recently, the U.S. Department of Commerce announced that it would prohibit companies in the country from selling any electronic technology or communication components to ZTE, a Chinese communicatio...[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]
1. Purpose Since the number of times the STM32 FLASH can be erased and written is limited, in order to protect our FLASH and extend the use time of the MCU, we can debug on the SRAM. SRAM is a ...[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]

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]
Example analysis: (using DMA mode) mian function: extern __IO u16 ADC_ConvertedValue; //The voltage value converted by ADC is defined in the context of ADC1_Init() float ADC_ConvertedValueLocal; ...[Details]
Assume that the crystal frequency of the microcontroller is 6MHz. It is required to use timer 1 in mode 0 to generate a continuous square wave pulse with a period of 500us, and output it from P1.0. T...[Details]
The circuit shown in the figure requires that the light is off when the machine is turned on. Press the button once, and the light D1 will turn on and automatically turn off after a delay of 10 secon...[Details]
Take serial port interrupt as an example: like: void serial() interrupt 4 { } and void serial_uart() interrupt 4 { } The functions of both functions are to define the serial port interrupt function. ...[Details]
