We have been able to debug the end-to-end connection of our overall system, with 2 fully functional pads with the central hub being able to control the 2.4GHz communication between the pads and allow for near simultaneous perception of the inputs. We successfully debugged our “multiceiver” functionality of the nordic nRF24L01+ modules. These packets are parsed by the central hub and sent to the computer via UART and serial output which the software is able to process and use as inputs to our game to get a viable scoring gaming mechanic. We definitely have a lot more features that we want to include but overall, the latency falls within our target latency and it provides good gameplay. Furthermore, the translation of the songs and parsing into the gaming format is pipelined and provides good integrity on the overall file.
Some improvements that can be made is the synchronization of audio and gaming inputs could be further improved. We can definitely add a lot more pads to the configuration. We still need to implement more sophisticated learning paradigms to our gaming design, such as the checkpointing mentioned within our reports. Our end-to-end assembly took some time but overall there is little to no bugs due to comprehensive testing and planning prior to assembly. There will need to be more iterative designing of the pad casing but overall we are almost on track.
We will meet over the week to continue working in lockstep to be able to reach our goals of more functionality added to our overall design by syncing each other on our progress every 2 days and combining the systems.
Still running into a few bugs on the digital to analog conversion on the daisy seed and will need to revisit the documentation to be able to debug the current problems.
