In this week I was able to link the pad system to the transmitter and then have it transmit the correct hit levels to the central hub. I am still calibrating the sensitivity and I will most likely have to increase the voltage threshold for the sending to make sure that noise is not caught. Currently it’s at 50 mV but will bring it up to 80 mV as most soft hits are around 100 mV on its first peak. I have started implementing the Multiceiver functionality of the Nordic nRF24L01+ where it can bin incoming messages to make it seem as if they come simultaneously and allow the receiver to hear on multiple channels. Also have started working on the DSP to make sure the audio is produced and heard on the user end.
I would say I am a little behind in terms of the schedule so I will definitely be in the lab this week to finish up these last few features and connect it with the software side. However, I feel as though this will not be too much of an issue as the synchronization can be made up with a sliding window of 5 ms to make sure that the hits are registered on time for the game.
I also have to measure end to end latency and notify the team so that they can create a game with enough of a leeway to accommodate for the delay.
