Re: Wiring Ultrasonic Ranger Finder
The Maxbotix sensor actually has several outputs you can use, depending on what you feel like interfacing with. It has a pulse-width output, which can be connected to a digital input and sampled for time high (if you can make it work via interrupts, that works even better), a serial input/output for using TTL-level serial communication, and an analog output for connection to an analog input on the CRio. I've found that the analog output is a little noisy (especially inside a robot) and isn't terribly precise, but the pulse-width output is great, and the serial output gives options to set when the sensor fires, which is useful for not interfering with other teams' sensors. Which input technique are you most comfortable with?
