mslogger-can-sd-blu-uno

An Arduino ATmega328P microcontroller application that logs Megasquirt (via CAN) and GPS data (via Bluetooth or Adafruit Ultimate GPS) to a microSD. Project is built using Platformio's code builder - see http://platformio.org/ and I'm using Eclipse as the IDE

After pulling down the project's repo, run the following platformio command platformio init --board uno --ide eclipse

To build the project (and upload to Arduino) you run platformio run -t upload

The project is not yet finished, but I will be updating as I progress...

The Arduino board actually used is the freetronics Eleven 100% Uno and then for CAN-BUS the seeedstudio CAN-BUS Shield - and then either a GPS or Blutooth shield...

  • Linksprite Bluetooth Shield for Arduino which required a bit a rewiring to enable the reset and command mode pins (see below). This was then paired to a GPS module which was a Qstarz 10Hz GPS device

or

  • Adafruit Ultimate GPS Logger Shield with additional external antenna kit. The Ultimate GPS Logger also includes a built in SD card wired to Pin D10 and a batt backed up RTC for the GPS, so the startup time is enhanced.

##Additional Wiring There is also a few additional wiring for a switch and status LEDs. The switch is used to turn the logging to SD card on/off. There are two (2) status LEDs for SD logging activity and CAN activity. A 74HC595 is used to drive 8 LEDs for an RPM limit status guage.

Pins used with Adafruit Ultimate GPS Logger Shield:

  • D0 DB9 Hardware Serial RX - DEBUG
  • D1 DB9 Hardware Serial TX - DEBUG
  • D5 LOG on/off switch
  • D7 Adafruit GPS - RX
  • D8 Adafruit GPS - TX
  • D9 SPI SS - CAN Shield
  • D10 SPI SS - SD Card
  • D11 SPI MOSI
  • D12 SPI MISO
  • D13 SPI SCK
  • A0 RED LED
  • A1 GREEN LED
  • A2 RPM DATA PIN
  • A3 RPM LATCH PIN
  • A4 RPM CLOCK PIN

Pins used with Linksprite Bluetooth Shield:

  • D0 DB9 Hardware Serial RX - DEBUG
  • D1 DB9 Hardware Serial TX - DEBUG
  • D2 [Bluetooth - RX]
  • D3 [Bluetooth - TX]
  • D5 LOG on/off switch
  • D6 [Bluetooth - RESET (*see below)]
  • D7 [Bluetooth - Command Mode / PIO11 (*see below)]
  • D9 SPI SS - CAN Shield
  • D10 SPI SS - SD Card
  • D11 SPI MOSI
  • D12 SPI MISO
  • D13 SPI SCK
  • A0 RED LED
  • A1 GREEN LED
  • A2 RPM DATA PIN
  • A3 RPM LATCH PIN
  • A4 RPM CLOCK PIN

Note: The Linksprite Bluetooth Shield for Arduino did not come with support for pins for reset or AT command mode enabling, so I wired these to set pins on the shield. This enables going into and out of AT command mode so that you can control the bluetooth module via software.
