2 CAN protocol
Reference to CAN2.0B
Baud rate：250kBit/s
Identifier: 11-bit (standard frame)
Description: All information is 8 bytes, BYTE 0 ~ BYTE 7, no use bit is low (0h), low bytes first, high bytes later.
3 Send message (key message)
Identifier: 0x007 (default)
Cycle: During power-up, the operation panel is always sent at a 100ms cycle, but immediately when the data changes (key status changes). data:
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x007 | Bit0:A1 Bit1:B1 Bit2:C1 Bit3:D1 Bit4:A2 Bit5:B2 Bit6:C2 Bit7:D2 | Bit0:A3 Bit1:B3 Bit2:C3 Bit3:D3 Bit4:A4 Bit5:B4 Bit6:C4 Bit7:D4 | 0xFF | 0xFF | 0xFF | 0xFF | 0xFF | 0xFF |
Description: If the value of the key when the key is pressed, the value of the key is 0.
4 Receive message (indicator light message)
Receive the controller data and control the corresponding indicator light according to the received data.
Identifier: 0x008（默认）
period： 100ms
Data: The indicator light receiving the CAN bus data control keys A1 to B4 is turned off
ID | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x008 | Bit0:A1.1 Bit1:A1.2 Bit2:A1.3 Bit3:Backlighting control enable Bit4:B1.1 Bit5:B1.2 Bit6:B1.3 Bit7: 无定义 | Bit0:C1.1 Bit1:C1.2 Bit2:C1.3 Bit3: No definition Bit4:D1.1 Bit5:D1.2 Bit6:D1.3 Bit7: No definition | Bit0:A2.1 Bit1:A2.2 Bit2:A2.3 Bit3: No definition Bit4:B2.1 Bit5:B2.2 Bit6:B2.3 Bit7: No definition | Bit0:C2.1 Bit1:C2.2 Bit2:C2.3 Bit3: No definition Bit4:D2.1 Bit5:D2.2 Bit6:D2.3 Bit7: No definition | Bit0:A3.1 Bit1:A3.2 Bit2:A3.3 Bit3: No definition Bit4:B3.1 Bit5:B3.2 Bit6:B3.3 Bit7: No definition | Bit0:C3.1 Bit1:C3.2 Bit2:C3.3 Bit3:No definition Bit4:D3.1 Bit5:D3.2 Bit6:D3.3 Bit7: No definition | Bit0:A4.1 Bit1:A4.2 Bit2:A4.3 Bit3: No definition Bit4:B4.1 Bit5:B4.2 Bit6:B4.3 Bit7: No definition | Bit0:C4.1 Bit1:C4.2 Bit2:C4.3 Bit3: No definition Bit4:D4.1 Bit5:D4.2 Bit6:D4.3 Bit7: No definition |
Note: 1. If the value of the corresponding bit in the data is equal to 1, the light is on; if the value is equal to 0, the light is out. 2.When the "backlight control enable" is 1, the "backlight control data" is effective, 1 backlight, 0 backlight out |

5 CAN key panel function setting
AN key panel function setting The communication node number and port rate of the CAN keyboard are set by the CAN bus data. When setting the CAN panel, the ID number is fixed to 0x7FF, and the data format is as follows:
|
Figure 2 CAN panel function setting the data format |
The setting parameter (BCDE) exceeds 10 when setting the port rate is invalid; ID number (BCDE) exceeds 0x7FF when setting the standard frame; invalid ID number (BCDE) exceeds 0x1FFFFFFF when setting the extended frame; and invalid BCDE is not 0 or non-0 xFF when setting the power button function.
The setting parameter (BCDE) exceeds 10 when setting the port rate is invalid; ID number (BCDE) exceeds 0x7FF when setting the standard frame; invalid ID number (BCDE) exceeds 0x1FFFFFFF when setting the extended frame; and invalid BCDE is not 0 or non-0 xFF when setting the power button function.
6 Uploading of the system parameter information
In 1S before the panel is powered on (A1-2 indicator light), the CAN key panel sends the system parameter information through 0x7FE at a baud rate of 250 Kbit/s, the specific format is:
CAN key panel system information
ID号 | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x7FE | 0x20(order number) | Hardware version number (Low in front, high in back) | Software version number (Low in front, high in back) | 0xFF | 0xFF | 0xFF |
|
|
The CAN key panel sets the parameter information
ID号 | Byte0 | Byte1 | Byte2 | Byte3 | Byte4 | Byte5 | Byte6 | Byte7 |
0x7FE | 0x21(order number) | Porter rate serial number (Low in front, high in back) | Received data ID1 type | Data ID1 (low before, high first) |
|
|
|
|
Receiving data ID type value =0: standard frame format; =1: extended frame format.
0x7FF data is sent by serial number 0-1 with a transmission period of 100ms
