EEPROM memory module-24C02

Overview

product description

This EEPROM module takes the M24C02 chip as the core and is used to save data during power-off. The working voltage is compatible with 3.3V and 5V systems, and is compatible with 100/400kHz IIC bus communication.
This module leads out the address interface A0/A1/A2 of M24C02. Users can change the bus address of 24C02 by configuring Ax, and mount up to 8 modules on the bus to achieve larger capacity data storage.
This module leads out the write enable port, and the user can enable or disable the write operation of 24C02 by controlling the WC# port.

Quad-axis, questions about I2C communication?
My understanding is this:But the result is this:I have learned I2C before, but I only learned about 1-to-1 communication. I don’t know much about 1-to-many communication. I hope you can give me some a
When a USB device is inserted in vxWorks, where is the software interrupt response point?
After the device is plugged in, an interrupt should be generated. I can't find where the interrupt point is. I'm anxious!
Problems with F149 driving L298N
I would like to ask you all, I use F149 to drive two 9V motors through L298N. The MCU IO port is directly connected to the motor driver module. It seems that all the connections are correct, but the o
