In my design, the USART (baud rate 115200) of STM32 needs to send 4000+ bytes per second to the host computer. The STM32 serial port DMA transmission mode (normal mode, non-cyclic mode) is enabled, an...
I want to design a way to convert CVBS TV signals to Innolux 5.6-inch TFT LCD screen. Can experts give me some advice? I have seen some companies use Taiwan MST chip solutions to make products, but I ...
How does the boot loader boot the kernel? Now my boot loader is running normally and the kernel image has been built. But I want to download the kernel image to the flash through the boot loader and t...
The bq24040 is a 1A single-input single-cell lithium-ion battery charger with auto-start function. The charger power stage and charge current sensing functions are fully integrated. The charger has hi...
I've been working on a prototype of SD card + USB mass storage these days. I accidentally deleted the old version of the library. The new website seems to be not fully up yet. The link cannot be opene...
Dear experts: I am now in a period of confusion about chip making machines. I don't know what I should learn. Some time ago, I programmed a clock made of 51 and digital tubes. Now I don't know what to...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
