Automotive Data Logger
The automotive data logger consists of NuMicro® M0A23 microcontroller and N9H30 microprocessor. M0A23 supports CAN Bus to log On-Board Diagnostics-II (OBD-II) data, which includes vehicle speed, engine RPM, engine coolant temperature, intake air temperature, MAF air flow rate and throttle position from engine control unit (ECU) simulator. Then M0A23 converts the OBD-II raw data and transmits the above information to N9H30. N9H30 shows the received information on 7” TFT-LCD human machine interface enhanced by emWin.
