This week I began integration of our full system, including debugging the hardware and software together.<\/p>\n
A lot of effort was spent working with the new hardware, particularly establishing a strong physical connection with the LCD pins, learning to pair a speaker to the BM83, which required some soldering and re-soldering, exchanging dead wires, and removing bad connections.<\/p>\n
Integration required a few attempts at debugging configuration issues since the audio path and UI had never been tested together. Eventually, with help from Xingran, I got this working. Now, the LCD is really dim, so I need to look into resolving this issue.<\/p>\n
I conducted testing with a guitar as in input signal. There is latency of about 200ms (rough estimate), which I think is induced mostly by whatever Bluetooth codec we are using. Also, the signal is relatively distorted, with a significant amount of noise.<\/p>\n
I successfully developed the delay effect, but noticed that it amplifies the noise due to the feedback loop.<\/p>\n
Next steps are looking into the LCD display issue, implementing the EQ effect, and finalizing our video, poster, and report.<\/p>\n
Here is quick video demo of playing guitar through BARI:<\/p>\n
