I didn’t have much feeling about the “hand-over party” before, but now a colleague has overturned my understanding of this term, as if he shouted loudly: “You don’t use your brain at work? I’m just sh...
The most commonly used compilers for developing STM32F are generally MDK and IAR. IAR is relatively simple and has slightly better compilation efficiency. MDK simulation effect is better, and most peo...
Last time we talked about using an oscilloscope to measure the signal of the car's air flow meter. This time we will talk about using an oscilloscope to measure the car's oxygen sensor. The oxygen sen...
[align=left][font=微软雅黑][size=12.0pt]The capacitor Ci next to R4 is equivalent to an open circuit for DC, so the DC component is not amplified; it is equivalent to a short circuit for AC, so the AC amp...
Activity details: Read the good book "Operational Amplifier Parameter Analysis and LTspice Application Simulation" for free, take notes, and thoroughly master the knowledge of operational amplifiersSu...
Scenario: Use CPLD to decode a serial data channel. The data has no accompanying clock and has a fixed frequency but a different single-bit phase.
My idea: I want to realize the acquisition of asynchr...
For a most basic single-channel pulse laser power supply, the basic function of the whole machine control circuit is to generate various control signals, including the trigger signal of the discharge...[Details]
