The code is as follows. After debugging, it runs stably (the display is stable and consistent with the air conditioner's display:loveliness:). Special reminder: a pull-up resistor must be added . I wa...
Has anyone used Microship's RN1810 wireless module? I'm using this wireless module to make a product recently but encountered some problems that I haven't solved yet. If you have any questions or woul...
After reading the third lecture on low power design
There are a few questions
1.Can any wire be used for this kind of fruit battery?2.Unused pins should be set as outputs
If there is no pull up or dow...
After the function of converting capacitance measurement to frequency output, this output waveform can be used to assist a dedicated frequency meter (advanced multimeters have frequency measurement fu...

In our common sense, the word technology often has two definitions. The first is the technology sealed in the laboratory. They are like flowers on the mountain top. Only a few people on the mountai...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[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]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
Artificial intelligence
There is no inherent bias in AI. It does not "think" something is true or false for reasons that cannot be explained by logic. Unfortunately, human bias exists in mach...[Details]
