No! The project is definitely not dead. We've just been too busy to update things here. To the people following our project, I apologize for that. However, I have good news :)
The first one is that now I have a Master degree, so I'm a MSc. in Computer Science. But I still have almost no free time because I've joined the PhD program, so I'm still a busy student ):
Regarding the project, I have 2 good news:
- PWM now appears to work on C.H.I.P.. We didn't even have to mess with the DAC from audio output pins. It works on pin PWM0 (pin U13_18). This means that both Arduino and Bluetooth connection are no longer need (theoretically, since everything together wasn't tested yet).
- Speech recognition in Brazilian Portuguese now works as standalone way of controlling our Samsung TV. Pocketsphinx package does the job. I'm gonna create another project describing the step by step procedures to use voice commands as an offline input interface of control.
