This week, our team has been working on simultaneously developing and functionalizing the Arduino Uno WiFi and the TI CC2650 microcontrollers. The Arduino was found to have extremely fast sampling time, and is more accurate overall. However, the CC2650 has more potential as it has 12-bit analog-to-digital values as opposed to the Arduino’s 10-bit.
We incorporated oversampling onto the CC2650 to simulate a 21-bit environment, but the sampling time proved to be too long for practical usage. In conclusion, we will still try to develop both boards simulatenously, since they both have their advantages and disadvantages: the Arduino samples extremely quickly and accurately; the CC2650 can connect to another CC2650 to transmit and receive data.
In the coming weeks, we will work on transceiving data on the Arduino, and improving sampling time and accuracy on the CC2650. We expect to be able to achieve at least one of these two goals.
