Function: This command registers the data for the designated character number.
Sequence: Type 6
Command:
Fig. 4-15-1
Data:
The binary data of the character drawn inside the 64×64 cell is converted into ASCII code as
shown below.
* Under the binary format, the “1” parts become “set”.
Binary → hexadecimal
hexadecimal → ASCII code
Fig. 4-15-2
The data is organized as follows: 8 bytes × 64 = 512 bytes
512 × 2 = 1024 bytes (ASCII code)
1024 bytes ÷ 128 bytes = 8
Since the amount of data transferred each time is always 128 bytes, the data is divided into 8
blocks, and transmitted and received.
The first 7 blocks are sent as shown below.
Fig. 4-15-3
The last block is sent as shown below.
