When we had a single crash in our first focus group, I didn’t think much of it. But when we had 3 crashes in our second focus group, something was definitely wrong. I had done preliminary testing but nothing that had showed frequent crashes so I had to think of the best way to crash […]

The pictures below are of the MSP430 schmartboard, the 150 mAh lipo battery, and the button we are using inside of a makeshift box. Our project box should arrive by the end of the week, so until then we are using a cardboard box. The protoboards will be secured with hook and loop tape before […]

At the end of each game, a progress report is generated with the student’s decisions, reaction time and a separate gyroscope/accelerometer report. Each file is stored on the Android with the date, time and description of the file. For example, the file uploaded with this post is called 04-02-2019_11_51_06_Gyro_File (04-02-2019_11_51_06_Gyro_File) Please note that the files […]

Our game utilizes Bluetooth to connect to the MSP430. However, there can obviously be problems with connectivity that have to be conveyed to the user so they can address the problem. (For the most part, power-cycling the button device, or charging the battery if it is too low. However, we have a separate error message […]

The video below shows the output of the gyroscope/accelerometer on the Schmartboard to a serial terminal. This data has been successfully sent to Unity, but it is difficult to get screen captures from the game that actually show the data being read in without lag. So, we are demoing the reading of data on a […]

The first video below shows the Schmartboard after it was programmed by the MSP430 launchpad. It shows the connections of each breakout board. The second video below shows the output from the Schmartboard chip to an Android Bluetooth terminal similar to the one used within Unity. It shows the gyroscope data being read in, as […]

It is important to follow TI’s recommendations when powering the chip, which are outlined in the Recommended Operating Conditions in SLAS789D, pg. 29. The Recommended Operating Conditions also clearly states that all VCC pins and all VSS pins should have the appropriate voltages applied to them, even if you aren’t using the chip’s analog capabilities.
