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]
Chip: STM32F103C8T6 Application Pin: Output: PA0, PA1 TIM2 CH2 channel To achieve 50HZ (20ms) adjustable PWM output on the PA1 pin, set the system TIMx_CNT=8MHZ=8000 000HZ, set TIMx_PSC=800-1, then T...[Details]
Although it is early summer, the Chinese smartphone market is still in the cold winter, just like Beijing in April with snow. For mobile phone brands caught in the middle, the cold is even more bit...[Details]
