Changed to a new CPU, BSP also changed. (Previously, the stream driver written by EVC was done) For SDHC (SDIO interface, SD card interface). Generally speaking, the following stream interfaces SDH_Cl...
In the current PC I/O mode, external devices are usually mapped to the CPU's I/O address space and are assigned a specified IRQ (interrupt request), or in some cases a DMA channel. These system resour...
[size=3][color=#252525]I would like to share a note from many years ago to show you how to combine digital and analog to create some innovations. Only by truly digesting and absorbing the principles a...
I recently encountered a problem in a project. Four subroutines are used in the main program. Do the types of the variables in the subroutines need not be defined?
If the variable type is not defined,...
The driver I wrote cannot be displayed after being burned in, and the driver written by others cannot be displayed after being burned in. I don't know what's going on. Could it be that the 5V 12864 ca...
Recently, the first Digital China Summit was held in Fuzhou, attracting many domestic ICT industry giants to participate in the exhibition. The long queues outside the venue, the noisy and exciting...[Details]

Designing for automotive LCD displays larger than 5" can be complex. The display source driver requires a supply rail called analog voltage device drain (AVDD) in the 10V to 15V range and two supply ...[Details]
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 order to strengthen the management of new energy vehicle charging facilities in our city, prevent and reduce accidents, protect the lives and property of the people, and improve the public safet...[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]
Friends who work in the photovoltaic industry, do you still remember the hard work on June 30 last year? How many people worked late into the night for months in a row just to connect to the grid a...[Details]
