1 1 Curve Display 1 Data Frame Data Definition Frame Header Data Length Command Data CRC checksum of the command and data Data Length N 2 Defined by R3 & Data length, include Description RA in command, data and CONFIG.TXT checksum Data frame is made up by 4 parts, shown as below. 0x80-0x84 Defined by R2 in CONFIG.TXT 2 Command Set Function CMD Data Description 0x80 ADR(0x00-0xFF)+Data_Pack Write data into the specified register Access Register 0x81 ADR(0x00-0xFF)+RD_LEN(0x00-0xFF) ADR(0x00-0xFF)+RD_LEN+Data_Pack Read data from the specified register Response from the DGUS module Access Variable SRAM 0x82 0x83 ADR_H:L(0x0000-0x6FFF)+Data0...DataN ADR_H:L(0x0000-0x6FFF)+RD_LEN(0x00-0x7F) Write data into the specified variable SRAM Read data from the specified variable SRAM ADR_H:L+RD_LEN+Data0...DataN Response from the DGUS module Trend Curve 0x84 CH_Mode(Byte)+Data0(Word)+...+DataN Write data into trend curve buffer. Buffer DGUS Register Space: 0x00H-0xFFH, is written / read by byte. DGUS Variable Data Memory Space: 0x0000H-0x6FFFH, is written / read by word. Data in Curve buffer is written / read by word. The communication between DGUS LCMs & Controllers (MCU) are driven by Variables that you may read and write in corresponding address.

2 2 3 Curve Display There are two methods to display the curve: Dynamic-curve Display Basic Graphic Display 3.1 Dynamic-curve Display Display Dynamic-curve in the different areas Add the dynamic-curve display functions in the different areas. The data source channels should be different. You can display up to 8 dynamic-curves at the same time. Display in the different areas simultaneously

3 Display Dynamic-curve in the same areas Add the dynamic-curve display functions in the same areas. The data source channels should be different. You can display up to 8 dynamic-curves at the same time. Display the curve in the same area

4 Send Curve Data to the Data Source Channel Send: 5A A F A Description: 5A A5 : Frame header. 12: Data length from 84 to 1A 84: Command for Writing Curve 12: Channel 4 & Channel 1, 8bit( ) : Data in channel : Data in channel Reset Dynamic-curve Step 1: Update the kernel to DGUS_V5.5 or above Please contact our sales to get the latest firmware. For steps on update refer to the chapter 1.4 of DGUS Development Guide. Step 2: Write commands to DGUS register to clear the curves. Register Address Definition Length(Byte) Description 0xEB Trendline_Clear 1 Write a special value to clear the data of corresponding channels. 0x55: Clear the whole dynamic curve data buffer. 0x56-0x5D: Clear the data of channels respectively from CH0 to CH7. After clearing the dynamic curves, this register will be reset. For example, Clear all channels 5A A EB 55 5A A5 : Frame header. 03: Data length from 80 to 55 80: Command for writing data into DGUS register EB: Register Address 55: The special value for clearing the whole dynamic curve data buffer Clear the special curve 5A A EB 5A 5A A5 : Frame header. 03: Data length from 80 to 5A 80: Command for writing data into DGUS register EB: Register Address 5A: The special value for clearing the data of channel 4.
