car data recorder

Overview

The automotive data logger consists of NuMicro® NUC131 microcontroller and N9H30 microprocessor. NUC131 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 NUC131 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.

- SAE J1850 PWM/ VPW
- SAE J1939 CAN
- ISO 9141-2
- ISO 14230-4 KWP
- Supports HMI enhanced by emWin

Specifications
NUC131 (32-bit Arm® Cortex®-M0)
- AEC-Q100 qualified
- Supports CAN protocol version 2.0 part A/B and bit rate up to 1 Mbit/s
- Supports up to 6-set UART with LIN and RS485 function

ATMEL CPLD program download problem (urgent)
When I use the atmel isp downloader to burn the program, the following message is prompted: Error: number of devices in chain file do not match number of devices in hardware.. Fail JTAG operations.. =
Is Fairchild's FIS1100 voltage design too abnormal?
FIS1100 is also a very good 6-axis sensor. When I read its PDF recently, I almost wanted to curse it? The voltage is designed to be abnormal for low power consumption. It is divided into analog and di
[cetk] Is there any update for the dll used in cetk test?
[color=#FF0000]As we all know, when cetk is tested, tux calls the test dll to perform the test, which means that the specific test items are defined in a table in these dlls. I originally thought that
ft245bm
Could you tell me why every time I read out the data of ft245bmBM, it is FE? No matter what I write into it, this problem will occur.
Looking for WinCE programming related information!
I just started to learn Wince programming and develop PDA programs. But I don't know how to start. I checked some information and found that most of them are EVC and EVB! I am more used to using C# an
