Data
Description
Access
register
interface
0x80
Distributed: register address (0x00-
0xFF)+ write data
Write register data at the specified address
0x81
Distributed: register address (0x00-
0xFF) + length of reading byte (0x00-
0xFF)
Start to read the register data of the specified
byte length from specified address
Response: register address (0x00-
0xFF) + length of byte data + reading
register data
Read TFT LCD module response of the
register
The TFT LCD module has 256Byte register, which mainly controls related hardware and is
addressed by the byte.
Access
variant
register
interface
0x82
Distributed: variant address (0x0000-
0xFFFF) + written variant data
Start to write data (byte data) to variant
memory area from the specified variant
address
0x83
Distributed: variant address (0x0000-
0xFFFF) + length of reading variant
data word (0x00-0x7F)
Start to read the data of the specified byte
length from the specified address of the
variant memory area
Response: variant memory address +
variant data length + reading variant
data
Read TFT LCD module response of the data
memory
The TFT LCD module is driven by variants. The variant value is separated from the variant
display format. The variant display format is downloaded to the TFT LCD module via the pre-
configured file. The variant values are transmitted to the TFT LCD module in real time via the serial
port. The variant memory is used to store the received variant value.
The TFT LCD module includes 64K word（128K Byte）variant memory, which is addressed by
word. The address is 0x0000-0xFFFF. When the user plans the variants, the variant memory
address is manually allocated by the variant length.
Write
curve
buffer
interface
0x84
CH_Mode
（ Byte ）
+DATA0
（ Word ）
+…+DATAn
Write data to curve buffer.
The CH_Mode defines the channel ranking sequence of further data;
Each bit of CH_Mode corresponds to a channel;
CH_Mode.0 corresponds to the channel 0. 7 corresponds to the
channel 7.
1 of corresponding position indicates that the corresponding channel
data exists;
0 of corresponding position indicates that the corresponding channel
data does not exist;
The low-channel data is ranked first.
E.g. CH_Mode=0x83（10000011B） indicates that theformat of
further data is (channel 0+channel 1+channel 7) +…+(channel
0+channel 1+channel 7)
The TFT LCD module includes a 8 K Word, can store the buffer of 8 curves, and can simply and
quickly display the curve for users.
The data in the curve buffer are 16-bit unsigned numbers.
