I have a 4-electrode conductivity electrode. I use a 1khz 2.5V square wave to excite the electrodes and connect two 470k resistors in series. I first found that the voltage on the electrodes is not sy
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
The electromagnetic environment of external radiation can enter the electronic system through the "front door" and "back door" coupling, causing interference, disturbance or damage to the electronic s
