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]
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]
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 In the general project development process, two or more microcontrollers are often required to communicate to complete data transmission. For example, a quadcopter wirelessly transmits d...[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]
This program mainly uses the comparison output function of the timer to generate PWM waves to control the LED. The comparison output of timer A corresponds to P2.3 P2.4. Therefore, a matching working...[Details]
