The board I bought from Yunhan on August 5th arrived today. Let’s unbox it.
This type of G4 board is a milestone among all STM32 boards
Previous boards, whether NUCLEO or DISCO debuggers, all used ST-...
When repairing an alarm, I found an integrated block. In principle, it is a single-chip microcomputer, but it is a dual-row 18-pin microcomputer without an external crystal oscillator. Pins 5 and 14 a...
I'm not very busy at work recently so I'd like to find a tutor or take on a project. Does anyone have any information? I have a bachelor's degree in computer science and 3.5 years of experience in emb...
For example, the high-density series: STM32F103XC, STM32F103XD, STM32F103XEdata shows that the dual-channel DAC conversion can be connected to an external reference voltage.Can the ADC conversion be c...
Now we need to receive infrared signals, and plug the OUT pin of the infrared receiving head into P2.3. We plan to interrupt and start timing once a jump occurs, but I don’t know how to write the prog...
When S3C2410 expands SDRAM, ADDR2 is connected to A0. Since SDRAM is a 16-bit address line, why doesn't it start from ADDR0? How does the CPU address it in this way?...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
