The CANL and CANH pins are used for CAN and ISO15765 communication.Ĭontact ISO-9141 K and ISO-9141 L are used for ISO-9141 and KWP2000 communication. Often, only ISO-9141 K line is used.
K-line (ISO9141/ISO14230(KWP2000)/dual K line)Ībility to supply voltage for programming and recording logs to a MicroSD card:Īn adapter capable of switching GND or voltage (from 5 to 25 volts) to pins 1,3,9,11,12,13 of the OBD2 connector or an auxiliary 2.5mm stereo connector:Īlso, the adapter’s firmware can record the log received from the 2.5 mm minijack (stereo) connector from Innovate Motorsports devices (lambda probes, etc.) via the MTS data bus protocol to an SD card. Minijack connector (stereo connector) is used to connect an adapter for supplying programming voltage. For example, on Mitsubishi, 18 volts are supplied through it, on Honda 5 volts, etc. (set automatically by a diagnostic program such as Techstream, etc. Since the microcontroller 2364 does not have a built-in SD card controller, work with a MicroSD card designed for recording logs is implemented here via the SPI bus. Support for K / L-line, in this adapter, is made on transistors. It is exceptionally easy to use and requires only two external resistors to set the output voltage). LM317L– voltage regulator 1.25-32 volts (adjustable, positive-voltage regulator capable of supplying 100 mA over an output-voltage range of 1.25 V to 32 V. 6251DS – CAN bus transceiver (transceiver)Ĥ. NCV7708B – Six-channel signal switcher (Double Hex Driver)ģ. LPC2364FBD100 – microcontroller: Arm7TDMI-S™ processor, microcontroller for embedded applications featuring a high level of integration and low power consumption at frequencies of 72 MHz. Features 128 kB of flash memory, 34 kB of RAM, Ethernet MAC, USB Device/Host/OTG, DMA controller, 4 UARTs, 2 CAN channels, 3 SSP/SPI, 3 I2C, I2S, 8-channel 10-bit ADC, 10-bit DAC, 2 PWM, 4 general purpose timers, low power Real-Time Clock with separate battery supply, and up to 70 general purpose I/O pins.Ģ.
