Serial communication not working?

[Lwangaman 1]

I am using an MSP-EXP430G2 (G2553) and I couldn't get CCS to work, but then I found Energia and voil

I found a working example in the TimerSerial example, which uses the include "#include ".

This was the only example that gave output to the serial monitor.

Did you reconfigure the RXD and TXD jumpers on the Launchpad?

The LaunchPad is a bit quirky for Serial communication.

 

1: Any MSP430 will work with TimerSerial (Examples->TImerSerial->TimerSerialExample) with jumpers in default position.

2: For Hardware based serial (e.g. MSP430G2553) TX/RX need to be swapped at J3.

- For LaunchPad v1.5 and later you can simply put the jumpers in horizontal position as noted on the silkscreen.

- For earlier versions, simply cross jumper TX and RX at header J3.

What is the difference between hardware based serial and well (software?).. other?

Hardware based is using the serial interface hardware, embedded in the MSP430. It requires you to put a byte in memory and will serialize it for you.

Software based will trigger the timer interrupt every bit and the software will set the I/O pin to the level corresponding with the desired bit.

Please have a look at the pins maps at http://github.com/energia/Energia/wiki/Hardware

 

The position of the straps is explained and pictured for the three different cases:

• MSP430G2452 on LaunchPad board revision 1.4 and 1.5
• MSP430G2553 on LaunchPad board revision 1.4
• MSP430G2553 on LaunchPad board revision 1.5

Thanks for this I checked the Launchpad schematic and now it makes sense. 

It is confusing since it kinda works with CCS and TeraTerm.
