Half Duplex UART on the Launchpad

Half Duplex UART on the Launchpad

[N]JC recently posted about developing a software UART which plays a part in his MSP430 oscilloscope project. For the uninitiated, a hardware UART uses the chip hardware to generate timing signals whereas a software UART depends on the software to generate timing signals and change pin states. This is also commonly known as bit-banging. Link to code after the jump.

Launchpad CAT5 Cable Tester

Launchpad CAT5 Cable Tester

[G]areth strikes again with his ultra simple cable tester. He seems to be working in networking his entire home, probably for home automation, which is something I would love to do when I have a place. He needed a tester to ensure his CAT5 cable and the final crimping was good. Commercial testers were too expensive and Ebay ones were of low quality. Being the DIY hacker type that he is, he used a Launchpad to send signals over a cable with LEDs on both ends – and appropriately calls them CatsEyes.

Powering the MSP430 without the Launchpad

Powering the MSP430 without the Launchpad

[G]areth over from square-disk managed to prove that you do not need a Launchpad to power an MSP430 without the Launchpad. His simple application consists of a blinking LED as a test setup. He did hit a roadblock when his rig did not startup. All he had to do was pull the RST pin high. Nicely done [G]areth! Video inside.

Creating Tunes with the Launchpad

Creating Tunes with the Launchpad

[E]nrico aka [e]ch0s managed to play the “Imperial March” tune through one of the MSP430’s pins using a piezo speaker. The code uses a pin(P1.2) to generate PWM waveforms at a particular frequency. This is easily done by raising the in high for a certain time and then lowering it for some time.

Keeping time with the MSP430

Keeping time with the MSP430

[B]oseji sent in his project about using the MSP430F2013 as a simple timer display. He uses a SN74HC595 as an i/o expander to two seven segment digital displays for displaying time. Two pushbuttons are provided for user interaction and for setting the timer. At the moment times can be set between 1minute to 3o minutes. His future enhancements include integrating an RTC for displaying time.

Launchpad to Breadboard Adapter

Launchpad to Breadboard Adapter

[G]eekDoc came up with a nice way to hook up a breadboard to the Launchpad. He came up with a breadboard adapter which carries both the signal rows of the LaunchPad to the prototype board pins. His design includes three separate PCBs – the adapter, a breadboard power supply and a Mini LaunchPad. His Flickr photostream has more pictures of the build.

Wiring the 32Khz Crystal to the Launchpad

Wiring the 32Khz Crystal to the Launchpad

[J]ustin writes about soldering the ultra tiny SMD 32Khz to the MSP430 Launchpad. He provides a step by step technique on how to get the tiny crystal onto the board with pictures. Soldering these parts can be quite intimidating to beginners – [J]ustin makes this easy – all that you need is some tape, a pair of tweezers and of course a soldering iron.
