Series Termination In practice, the resistor (R) can be omitted at the buffer output because impedance matching is difficult to achieve due to its dynamic impedance change with frequency. Advantages
Let's talk about "fake" today
Have you ever wondered: the circuit cannot be debugged, "I may have bought a fake chip"?
Do you have any doubts: Is it a problem with your circuit design or debugging?

STC89c54RD+ defines array xdata a[18] _at_ 0x001d; I can change its value with the keyboard, but after powering on, its value changes randomly. I would like to ask you how to ensure that its value is
I am using a pressure sensor now, but the no-load voltage of the pressure sensor is not 0.
The sensors are all different.
A great person told me to reset the software, but I don't know how to do it. T
