After installing termux, php and Kedao Cloud on your phone, anyone in the same LAN can access it. If you want to access a device that is not in the same LAN, that is, remote access, you need to use so...
In the DSP world, due to the limitation of DSP chips, fixed-point decimal operations are often used. The so-called fixed-point decimals are actually decimal operations performed with integers. The fol...
I think ADC and timer are the difficulties in STM32F103 because there are too many threads. Today I want to make the simplest ADC, which is software-triggered ADC.
First, add a PC3 to CUBEMX as last t...
When choosing a DC-DC chip, how much margin do you need to reserve for the output current? I chose a 3A chip, and it was already heating up when it output 2A....
