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...
