The ADC of F28027 has a limit time of 13 clocks, and the sampling clocks can be staggered. In this way, it can reach 4.6M. However, the converted data must be used, otherwise no matter how fast the AD...
Design requirements: 1: The red light of the tester flashes or the buzzer emits a long sound, indicating that the measured value is a logic high level. 2: The green light flashes or the buzzer emits a...
When measuring resistance values, the Wheatstone bridge is often mentioned. Why can using it improve the test accuracy?
If you want to measure resistance, two resistors can also be measured.
Are the f...
