I am a junior in electronic information engineering. I have read some information about embedded systems online and plan to work in this field. I have not yet decided which level I will work in. Do yo...
Traditional multi-machine communication systems generally require four wires: 1. Power line; 2. Ground line; 3. Send signal line; 4. Receive signal line. However, for systems with a long distance betw...
For the charging part of the emergency light design, I used the MAX745 charging chip from Maxim, which uses dual-loop control and a PWM operating frequency of 300kHz. The charger using this control ch...
I was bored and suddenly remembered a problem I encountered last year that was never solved: I have an analog signal that I want to split into two paths and use analog circuits with different function...
Do you still remember the STM32F7DISC development board from the community activities two years ago? Today, MicroPython has upgraded its support for it and can use external SRAM. The STM32F7DISC devel...
