Maybe something else first prototype project on github lib for cheap fram FM24C04. Windows Xp Sp3 Bg Language Pack Download there. Also work on arduino nano, not ported yet. Read TT voltage to display current drive and hydrotransformator lock. be careful the ELM327 USB interface only specifies OBD 2, I'm not sure if an adapter cable to make the diagnostic port connector interface with the scanner will be of any use, the difference between OBD 1 and OBD 2 is more than just the connector, I suspect that there are significant difference in the way data is sent that makes an OBD 2 scanner unable to read OBD 1 codes unless the scanner is. Also work on arduino nano, but to spi SD card logger, not ported yet. Piratas De Silicon Valley Torrent Latino. To make this CAN BUS shield convenient to interact with cars, it has an MCP2515 CAN-BUS controller with SPI interface and MCP2551 CAN transceiver to give you Arduino/Seeeduino CAN-BUS capability. Todo 1.read raw oxygen sensor voltage to diagnose it. With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device or data logger. Can calculate and save to fram trip, time and fuel consumption. I check fuel consumption calculeted and real - 0.5l differense on 400km. Can calculate fuel consumption in liter per hour and liter per 100km. Can read toyota obd1 protocol, which include Injector pulse width (INJ) Ignition timing angle (IGN) Idle Air Control (IAC) Engine speed (RPM) Manifold Absolute Pressure (MAP) Engine Coolant Temperature (ECT) Throttle Position Sensor (TPS) Speed (SPD) Voltage feedback from oxygen sensors and some flags, like enable Air conditioner, cold engine, enrichment e.t.c 2. Second work on maple mini + 2.4 SPI TFT ILI9341 Features 1. First prototype work on arduino nano and 0,96 i2c oled. I am from Russia, so, sorry for my bad English I am work on Toyota OBD1 protocol car computer.

Here is an example code of a simplest engine RPM indicator, which uses the pin 13 LED (built in every Arduino board) to indicate whether the engine is above 5000rpm.

Power Lines: Red: VCC (connecting to Arduino's 5V/VCC) Black: GND (connecting to Arduino's GND) Data Lines: White: Rx (connecting to Arduino's serial Tx) Yellow: Tx (connecting to Arduino's serial Rx) The Library A dedicated Arduino library is developed and maintained regularly, providing a set of easy-to-use APIs to retrieve realtime data from a vehicle. Your Arduino setup will look tidy in car with only one cord. They are connected to Arduino to provide both power supply and data connection. Some Toyota ODB-1 ECUs have a serial output allowing an appropriate scan tool to read and display live engine operating parameters, similar to what a standard OBD2.ДЄ cable coming out from the adapter splits into two 2-pin Dupont connectors with one for power (VCC/GND) and one for data (Rx/Tx). I will be removing the board from the ELM327 Enclosure and then bypass the USB bridge chip and attach the Serial TX/RX pins of the arduino to the Serial TX/RX pins onto the ELM327 board, program the arduino and attach the ELM327. Hack an ELM327 Cable to Make an Arduino OBD2 Scanner.
