I use the MCU that comes with the AVR for sampling. The power supply of the sensor is not the same as that of the MCU. How can the signal output by the sensor be accurately collected by the MCU? Is it...
1. AC equivalent circuit analysis method First draw the AC equivalent circuit, and then analyze the AC state of the circuit, that is: when the circuit has a signal input, whether the voltage and curre...
I used the RTC assembly file RTCASMFunctions_IAR.s43 provided by Ti. But strangely, after I added the .s43 assembly file to the project, there was no file when compiling. When downloading, there was a...
For analog circuits, the design of the ground wire is a critical link. Many circuits such as digital meters, AD/DA interface boards, etc. have a distinction between digital ground and analog ground. A...
