MSP430FR2476: No RX or TX interrupt is being triggered. eUSCIB0 on MSP430FR2476

Michael Kegler

Part Number: MSP430FR2476

Hello,

I hope someone can help me. I am having problems with two MSP430FR2476 launchpads
that are supposed to communicate via I2C.

No RX or TX interrupt is being triggered.

I downloaded the example from GitHub and adapted it for MSP430FR2476.

Can anyone help me here?

Here is the code for the master and slave: MCU-MCU.zip

Hi Michael,

Can you check if the error persist even when using the CCS examples for this device? I want to rule out the issue could be with the hardware.

Best Regards,

Hello Diego,

I have tried all the examples from Driverlib and the examples from slac781b. All with the same result.

Have you checked the signal on the pins? Is there a start condition? Slave address sent?

I have resolved the issue. The pull-ups were not properly connected. Thank you to everyone who responded to my request. Have a wonderful third Advent.
