The input pulse train at the control signal will turn the rotor to the desired position. The LED circuit and current amplification circuitry is being constructed and designed right now.The angular positions of a servo motor are controlled by the pulse width modulation(PWM).
We are currently working on the Viterbi algorithm as well as initializing the HMM. The next step for the LED circuit is to design for the green and red transistor circuits and debug the mode select portion.ġ0/28/15: The forward and backward algorithms have been completed in the MATLAB simulation. We designed the blue diode transistor circuit to match the 20 mA current specification. The PNP transistor will limit the current draw that we don't desire while keeping the current draw that will give us the bright LEDs. We have begun work on designing a PNP transistor circuit because there is a problem with current draw during both the saturation and off modes of the NPN transistor. Work was begun on integrating all HMM algorithms into a cohesive simulation. Forward and backward algorithms were tested to ensure that they worked correctly. Completed work on the Viterbi algorithm for the MATLAB simulation.
#Midi monitor matlab software
: Began drafting sample Javascript and XML files for the Mixxx DJ software plugin. More work was done on the Viterbi algorithm as part of the process towards a complete HMM simulation.
#Midi monitor matlab code
We also began drafting XML and JavaScript code for Mixxx software application as well as continued experimentation with Pixy LED detection. The object detection is initially successful. We went back to an earlier design to see how Pixy object detection worked, and the results suggested that the design is appropriate.
: Designing the PNP transistor circuit did not meet the goals of the LED circuit. Research has been completed for communication between Pixy and the Raspberry Pi. The Viterbi algorithm was coded and tested successfully. Although there is still testing to be done, we finalized the design of the circuit. There has also been work done on improving LED tracking of the glove. : We have begun conceptualizing the glove design. Work on the Mixxx communication has also been postponed until we acquire a MIDI controller. Work on the LED circuit has been postponed because we are waiting for parts to arrive. The code that updated the parameters of the HMM has been completed. : Work has been begun on SPI communication between the Raspberry Pi and the Pixy. SPI communication has been established between the Pixy and the Raspberry Pi and we are able to extract data about the objects detected from the Pixy onto the Raspberry Pi. Glove design and building has begun and will continue next semester. : We have finalized the circuit for the glove. Work has been done on extracting the relevant object data from the Pixy camera onto the Raspberry Pi. Measurements were taken for the circuit enclosure and a design is currently being created. We also designed a layout for the perf board and began soldering. : We analyzed MIDI signals transmitted from a Numark MIXTRACK DJ board with the MIDI monitor application. Once several gestures have been successfully tested in the MATLAB simulation, we can begin transferring the code to C. Object data has been extracted from the Pixy system for testing in the MATLAB HMM simulation. Several more components were acquired and installed for the glove. We will now be working on sending the appropriate MIDI signals to the DJ software. Data can now be sent from the Raspberry Pi to the DJ's computer.
#Midi monitor matlab serial
: A serial data connection has been established. Continued to debug HMM and have corrected several issues with the simulation. : Attempted to send MIDI but have experienced faulty MIDI recognition. : Began the training process for the HMM using the training data collected last week. Have received complete MIDI signals although they were not the signals that were supposed to be transmitted. Analyzed raw data sent from the Raspberry Pi. : Still receiving errors due to faulty MIDI recognition. Continued work on MIDI without any progress. Finished soldering LEDs to the leads of the circuit.
Installed circuit components into the box. All subsystems completed except for parts of HMM algorithm.
