I'm working on something related to electric energy measurement recently. When collecting voltage and current signals, someone suggested using a differential circuit. Why can't we just do voltage divi
When we design power supplies, especially when powering circuit boards, the most commonly used and most reliable method is: control transformer + 78xx (or 79XX). The reason is very simple. The control
1. The mileage pulse signal is input from external 0 (INT0). For each pulse signal, the system adds 0.1km and records the mileage. 2. The interrupt method of timer Tx is used to achieve 10s timing (bu
Have you ever used the CAN module of the TM4C series microcontroller? When entering an interrupt, you need to read the CANINT register, right? It is used to determine the current interrupt source. How
[table=98%,rgb(238, 238, 238)] [tr][td]As the title says, I want to tinker with ST's sensor [b]LSM330DLC[/b] recently. I used the development board kit before. ST has software for the Windows platform
What is the reason for the phase difference between the input and output of the op amp? What methods can be used to eliminate or reduce the phase difference?
