- Page 2 Most importantly, you will need a sense of adventure, DIY spirit, and hacker curiosity. Hardcore DIY electronics is not a trivial pursuit, and HackerBoxes are not watered down. The goal is progress, not perfection. When you persist and enjoy the adventure, a great deal of satisfaction can be derived from learning new technology and hopefully getting some projects working.

Next, in the CC1101_RXinterruprt le, nd the line calling function attachInterrupt() and change the rst parameter (interrupt number) from "0" to "4". This is done because pin 7 of the ProMicro is associated with interrupt #4. HackerBox 0034: SubGHz: Page 12...
