I am trying to use on chip I2C on NXP P89LPC954 microcontroller(80C51 based) for voltage monitoring.
- I have two voltage monitoring chips of same kind(same chip with same register address) connected to I2C pins of microcontroller.
- Now in order to write to one of the chip how can i send address and data to that specific chip registers.What i mean is both are connected to the same pins of microcontroller(SDA,SCL).
Microcontroller used :NXP P89LPC954
Voltage monitor ic :MAX6656
Interface : I2C
