6.1.1 Add User Bitmapped Character
Serial Syntax :
4DGL Syntax :
cmd : 41hex, Aascii
group : selects the appropriate bitmap format
numb : bitmap character number to add to memory:
data1 to dataN : number of data bytes that make up the composition and format of
Description :
internal memory. There are 3 different size bitmaps available, 8x8 format, 16x16
format and 32x32 format. The desired format is selected by specifying the appropriate
value in ‘group’.
Example1:
This adds and saves user defined 8x8 bitmap as character number 1 into memory as
seen below.
00hex selects the 8x8 bitmap format
01hex selects the 16x16 bitmap format
02hex selects the 32x32 bitmap format
0 to 63 (00h to 3Fh), 64 characters of 8x8 format when group = 00hex
0 to 15 (00h to 0Fh), 16 characters of 16x16 format when group = 01hex
0 to 7 (00h to 07h), 8 characters of 32x32 format when group = 02hex
the bitmapped character. The 8x8 bitmap composition is 1 byte wide (8bits)
by 8 bytes deep which makes N = 1x8 = 8. The 16x16 bitmap composition is
2 bytes wide (16bits) by 16 bytes deep which makes N = 2x16 = 32. The
32x32 bitmap composition is 4 bytes wide (32bits) by 32 bytes deep hence N
= 4x32 = 128.
