CHARACTER COMMANDS
The character commands treat the display like a 20-column, 4-row character display
where the characters occupy 6 x 8 pixel elements. Note that there are 20 character
locations on a row, each 6 pixels wide. This current implementation only uses 120
pixels of the 122-pixel wide display. The spare two-pixel columns are on the right of the
display and cannot be affected by the character commands. The controller has a fixed
space 5 x 7 font set for the printable ASCII characters in range: 0x20 -> 0x7E. The
controller also recognizes three special characters that do not affect the display.
1. CR: (0x0D) Increments ChrPosR.
2. LF: (0x0A) Sets ChrPosC = 0 and increments ChrPosR.
3. BS: (0x08) Decrements ChrPosC if ChrPosC > 0; it is non-destructive
B.5.1
The ChrPos command sets the character position to ChrPosC, ChrPosR. This
command has no effect on the display except for moving character cursor if it is turned
on.
B.5.2
The ChrPosInc command increments the character position. This command has no
effect on the display except for moving the character cursor if it is turned on.
B.5.3
The WrtChr command sets ChrPos to (ChrPosC,ChrPosR), then writes ASCII
character to ChrPos.
B.5.4
The WrtChrInc command sets ChrPos to (ChrPosC,ChrPosR), writes an ASCII
character to ChrPos, and then increments ChrPos.
