The 1138 tft2.4 example downloaded from the Internet does not work on the 8962 screen of the same model.
The sd_FAT32 driver example also doesn't work on my board, but the 8962 example wor...
Maybe you will think that the blogger is an angry young man when you see the title "Disclose the intentions of foreign semiconductor companies to set up R&D centers in China?", but I really don't know...
After AD sampling and algorithm processing, I get a zero-crossing signal as a square wave. This signal is assumed to be a variable A. I want to set a software interrupt that is triggered by both edges...
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]
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[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]
I recently upgraded MDK to V5.25 and found that there are many libraries in the Managing Run-Time Environment. Compared with the past, it is much better, from the bottom-level driver to the upper-le...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[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]
