As the title says, the hardware connection of the DM9000A of the Feiling development board: 1. The interrupt port is connected to the GPF7 of the 2440 to respond to the network card interrupt; 2. The ...
430G2553 launchpad test timer capture function found that when using switch+case, it can not enter the capture interrupt, but can enter normally without it, but the overflow interrupt can enter: #incl...
Is there a command in C that can write the entire program to a specific location in the flash and then write it together with the bootloader? The general idea is to burn both things in together. And n...
China's photovoltaic power generation installed capacity achieved rapid growth in 2017, and distributed photovoltaics achieved explosive growth. In 2017, the country's photovoltaic installed capaci...[Details]

1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]
1. Placement suspension void NVIC_Configuration(void) { NVIC_InitTypeDef NVIC_InitStructure; /* Set the Vector Table base location at 0x08004000 NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x4000)...[Details]
1. Purpose In actual product release, if the program stored in the MCU Flash is not protected, some illegal companies may read the program in the Flash through an emulator (J-Link, ST-Link, e...[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]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[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]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
background After the hardware engineer completed the PCB and schematic design, the routine was modified according to the tutorial of Zhengdian Atom to verify the correctness of the hardware. STM32F...[Details]
1. Determination of STM32 ADC sampling frequency 1. First, read some information to determine the ADC clock: (1) The ADCCLK clock provided by the clock controller is synchronized with the PCLK2 (A...[Details]
