CAN BUS Interface

adb command:
Set the bitrate ( baud rate ) before all operations
Example: Set the bitrate of the can0 interface to 125kbps:

ip link set can0 up type can bitrate 125000

Quick test
Once the driver is installed and the bitrate is set, the CAN interface has to be started like a standard net interface:

ifconfig can0 up and can be stopped like that:

ifconfig can0 down

The socketCAN version can be retrieved this way:

cat /proc/net/can/version

The socketCAN statistics can be retrieved this way:

cat /proc/net/can/stats

GPIO Interface

1. GPIO interface as shown below,

How to read or set the value of the gpio

GPIO0~7 (IO number)

a)When the software configures the IO port as input, (Negative trigger).
Configuration command: gpiocontrol read [gpio number] For example: Setting gpio 0 as the input state, and read the input level
diamond :/ # gpiocontrol read 0
diamond:/ #
Trigger voltage: The logic level is ‘0’, 0~1.5V.
Non trigger voltage: The logic level is ‘1’, the input IO is floating, or beyond 2.5V, but
the maximum input voltage must be less than 50V.

b)When the software configures the IO port as output, it is an open drain output.
Configuration command: gpiocontrol [gpio number] set [output state] For example: Set gpio 0 as output state and output high level
diamond:/ # gpiocontrol 0 set 1
diamond:/ #

When the output IO is enabled, the logic level is ‘0’, and the IO voltage is less than 1.5V.
When the output IO is disabled, the logic level is ‘1’, and the rated voltage of the IO must be less than 50V.

3.4 ACC Setting Path
ACC settings located in ACC Settings under the category of System in the Settings of Android OS. Please refer to Figure 3 1, 3 2 and 3 3:

Clock go to Settings and select “ACC Settings” as shown.

ACC settings as shown in Figure 3 4 & Figure 3 5.

1. The main switch of the three functions controlled by ACC, namely, light up the screen, close the screen and shut down.
2. The switch of close screen function controlled by ACC.
3. Click to pop up dialog box as shown in Figure 3 5, to ed it the screen off delay time after ACC outage.
4. The current screen off delay time after ACC outage.
5. The switch of Trigger to shut down function by ACC outage.
6. Click to pop up dialog box as shown in Figure 3 6, to edit the shutdown d elay time after ACC outage.
7. The current shutdown delay time after ACC outage.

Memory Card Instructions

• The memory card and the card slot on the device are precision electronic components. Please align to the position accurately when inserting the memory card into the card slot to avoid of damage. Please slightly push the upper edge of the card to loosen it when removing the memory card, then pull it out.
• It is normal when the memory card getting hot after long time working.
• The data stored on the memory card may be damaged if the card is not used correctly, even the power is cut off or the card is pulled out when reading data.
• Please store the memory card in packing box or bag if not used for a long time.
• Do NOT insert the memory card by force to avoid of damage.
