 FIRST robots definitely meet many commonly agreed upon definitions of robots. Some will disagree. Good for them. In my opinion, it's not worth arguing over. - Mikell Taylor [more] |

Re: 80 millivolt sensor on breakout?
The NI 9201 has 12 bits of resolution over a 20V input range - ie 5mV resolution. If you need more precision, you'll need to consider an amplifier to increase the signal level or, perhaps, a SPI or I2C A/D converter or similar. Or is 5mV resolution sufficient?
NI offers a number of analog converters similar to the 9201 but designed for greater precision. Unfortunately, these aren't available for FIRST teams to use (at least for this year since the FPGA is fully locked-down). Russ
