What is BCD code?
The most commonly used numbers in daily production and life are decimal numbers, and all data in the microcontroller system are binary in nature, so our smart predecessors created BCD code for us. BCD
dnw suddenly stopped working
Question: (1) This dnw is said to be a new version. When I was burning it, the computer blue screened and then this dnw could not be used. (2) There is no ini file. Many people say that just deleting
Ask for analog electronics knowledge
Question: Why is it said that the capacitive reactance of Cu" is much smaller than the total collector load resistance RL', so the current in Cu" can be ignored? Please give me some advice. Thank you
EZ430 chronos RF side cannot read
