With the development going deeper, software development and hardware become more and more closely linked. The lack of hardware knowledge creates obstacles to my development, in addition, the chip technology is basically used by foreign companies.This is a huge constraint on system-level design.

Basic knowledge of current absorption, current pulling, current filling, pull-up resistance, drop-down resistance, and high-Resistance Mode

operating current of the light-emitting diode is 5 ~ 10mA ). Up/down resistance I. Definition 1. Pulling up is to embed uncertain signals in a high level through a resistor! "Resistance simultaneously throttling "! The same is true for the drop-down! 2. the pull-up operation injects current into the device, and the drop-down operation is the output current. 3. the weak ones only have different resistance values for the pull-up resistor. There is no strict distinction between them. 4. The abilit
