​

Currently implemented in the prototype (as of 11/28/2016):

​

• Read/decode CAN bus regular/extended messages

• GPS/GLONASS

  • 10 Hz update rate

  • 167 channel

  • 2.5m accuracy

  • NMEA output

• 8 analog inputs with 5V input range on each channel, 12 bit resolution, up to 200 Hz sample rate

• 2 digital inputs with 5V input range to measure period, pulse width, pulse count, state to microsecond accuracy

• Multi sample averaging modes for analog and digital inputs

• 4 Lookup tables, 16 entries each, for interpolated data translation of any input

• Input naming, up to 15 characters

• WiFi based on the ESP8266

  • WiFi access point

  • WiFi station

  • DHCP client/server

  • 2 outgoing TCP connections (TCP client)

  • 2 incoming TCP connections (TCP server)

  • mDNS server for the TCP server

• Micro-SD card

  • Simultaneously log to 2 files

  • Automatically delete "short" files (files that have less than "N" seconds logged)

  • Automatically delete oldest log if more space is needed

  • Format card

  • Test read/write speed

  • Trigger logging on power up, GPS time sync, button press, speed, or altitude

• USB

• Racechrono $RC1, $RC2, $RC3 output formats up to 100 Hz update rate

• Desktop software for complete device configuration, Windows currently
