Explain the principles and experimental standards of electromagnetic compatibility, explain the principles and selection of commonly used devices, and explain protection circuits
The package written in the data sheet is QFP, but the protel99se package library includes QFP, QFP-1, QFP-2, QFP-3, QFP-4, etc. Which one should I choose?
Now we need to read and write two identical slave devices through the I2C interface; but the slave address of this device is fixed; so there will be an address conflict; May I ask: is there any simple
