Look what the mail man brought in today. This little beauty here to your right is a prototype of the new upcoming Mindsensors Numeric Pad. It’s a very nice capacitance proximity detection based keypad meaning it can tell when you’re touching it without the need for actual switches. That does mean that if you like to wear gloves while working with your robot, you will only be able to make it work if you wield a hotdog-type sausage.
Using it is as easy as as reading the 2 registers containing the state of each key in binary format. The only small tricky bit is that you need to configure some registers first to “tune” the chip. Lucky for us, Mindsensors has all those values available in the NXC library. I can’t wait to make this thing work in ROBOTC. You can expect a driver for this sensor in the next release of the ROBOTC Driver Suite.
