I want to test the efficiency of a program. I have tested this efficiency through the pb platform (if it is not embedded in this platform, it will not show the name of this program, but unknown instea...
I used a second-order filter, which was divided into 1024 parts. The 430 ADC at the output could not be detected, but the multimeter had digital signals, so I added a first-order emitter follower. The...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
1. Limited secondary filtering
