Meeting Summary 14OCT

During this meeting, Professor Spinelli and I discussed how to move forward from the success experienced last week. The waveform data from the accelerometer could use some simlple filtering (i.e. a bandpass filter with a cutoff at my minimum and maximum desired tempos). In order to create that filter, I need to find the sample rate for the accelerometer and look at the datasheet to determine its max G’s and how it produces data (i.e. unsigned integer). In addition I will explore using the magnitude of the vector (sum of squares of components in the x, y, and z axes). Simultaneously, I will be working on modifying the nRF UART app to simply send one parameter and instead of scrolling, it should update the number to overwrite the previous number. We also talked about the case I would need to design as a housing for the device. It would be 3D printed and designed in a program such as SketchUp or SolidWorks. It would contain the battery to power the chip, the voltage of which will be determined by looking at the spec sheet and measuring the power coming into the IMUduino via USB. Finally we also solved the problem where MATLAB and Arduino were trying to use the same serial port. All I need to do is close the serial monitor.
