MSP430FR2632: Can I change the I²C address through I²C command ?

Part Number: MSP430FR2632

Hi,

Can I ask the MSP430 to change his I²C address trhough a WRITE I²C command.

The goal is to send a command, the msp430 will change his own address, then reboot.

Thanks,

Charly.

    There is no native command, but you could certainly write code to do this. I don't know that you would have to reboot, just restart the I2C system.

    Hello,

    As Keith mentioned, you would just need to code in both command to start the process, then code to change the Slave Address register.

    Also keep in mind you can have up to 4 Hardware Slave Addresses (SAs), with accompanying interrupts that you can pre-program into the device. so different SA's can have different commands/actions the respond to. You could also further take one of those HW SA's to do SW SAs up to 2^10 addresses. See section 24.3.9 in the User guide for more details.
