This tutorial is mainly for the STM32F04x series of microcontrollers. For the clock of the STM32 microcontroller, people who have used STM32 must be more clear. STM32 is a microprocessor based on the ...
Adafruit's CircuitPython has supported SAMD21/D51 microcontrollers for a long time, and now micropython finally supports SAMD series microcontrollers.https://github.com/micropython/micropython/commit/...
I use a queue to let the data buffer enter the queue first and then exit the queue. Finally, I use the serial port to transmit large data, but there is still serious packet loss or serial port jamming...
Multimeter is the most basic tool in the field of electronic testing and is also a widely used instrument. Due to its low price, simple operation, complete functions and wide use, professional electr...[Details]
With the rapid development of electronic technology, electronic equipment is also developing towards functional integration and miniaturization, which brings us many conveniences, but the electromag...[Details]
According to reports, the European Space Agency (ESA) has commissioned the Swiss startup "ClearSpace" to submit a plan to launch a "scavenger" in 2025 to clean up a 100-kilogram piece of debris in ES...[Details]
Sometimes when purchasing an R-type transformer, you may encounter the problem of uncertainty about the capacity. This is because the voltage of some equipment is special, or the purchasing personn...[Details]
