MSP430 Remote Temp/Humidity probe with DHT22 and nRF24L01

This is a test program / proof of concept of reading the DHT22 using Timer1A in the MSP430G2553 on the Launchpad (or whatever).

Hardware

You'll need:

• MSP430 Launchpad with MSP430G2553 (or something else)
• DHT22 with required pullup resistor
• nRF24L01 module from your favorite chinese supplier

Build, program, and see the temperature and humidity on your favorite serial console program.
