[MSP-EXP430G2 - two pair UART and I2C communication]

I've setup everything one more time and I've noticed that stupid jumper Anyway, examples works!

 

Now I have to write program that supports two way communication: master sends 'data' -> slave recieve it and process it -> slave sends 'processed data' back to master. It is possible, right?

 

EDIT:

Nvm, I got this Thanks for the help.

I've tried that Energia software and it looks really cool!

 

First of all I've tested UART echo - so easy and works very well.

 

I2C should be enough for me so I've tested Energia's Wire examples (sender - reader) -> https://github.com/energia/Energia/tree/master/hardware/msp430/libraries/Wire/examples

 

I've connected two MSP with each other: P1.7 - P1.7 and P1.6 - P1.6.

One of them is connected with PC and should write data that is send through I2c. Unfortunately it's not working :/ I'm not sure why... Maybe something with that HW/SW jumpers? In what position they should be?

 

EDIT:
I've also connected that pullup resistors. Still the same.

Thanks, guys. I'm gonna play with this tomorrow.

Hi!

I've got a launchpad MSP-EXP430G2 rev. 1.5 (with msp430g2553) and I need to use two pair of UART (2xRx and 2xTx). To be more specific, here's what I have to do:

• PC transmits 'data' to MSP --> MSP process that 'data' --> MSP transmits 'processed data' to another MCU...
• PC receives 'processed data' from MSP <-- MSP process that 'data' <-- MSP receives 'data' from another MCU...

In short:

PC -> MSP -> another MCU -> MSP -> PC

 

Is it possible to do this with that launchpad? If it is, could you hint me some examples? I'm completely new with MSP.
