Add'l Info Link | SGX-120 Hardware Reference |
Text sent serially to SGX-120L is immediately printed to the screen (at the current location and in the current font size). Send Hello World!
and Hello World! appears on the display.
SGX understands traditional control codes, such as Tab
LF/CR
FF/Clear
Backspace
etc. Additional features (drawing lines, changing font size) are mapped to other control codes or Escape
sequences. SGX can receive and store full-screen bitmaps (120x32 pixels), which may be recalled to fill the screen, or may be used as alternative custom fonts. Here's a quick overview of the instruction set:
Printing Position | Home, Tab, Linefeed, Carriage Return, Vtab, Set-Position (ctrl-P) |
---|---|
Font Size, Bitmap Pattern | ESC F# (set font size and/or bitmap source) |
Clear Screen (all or part) | Backspace, Clear Screen, Right-align (ctrl-R) |
LCD Backlight | On (ctrl-N), Off (ctrl-O) |
LCD Contrast | ESC + ESC - ESC = (up, down, reset) |
Graphics: Plot a Line | ESC L x1y1 x2y2 and ESC T x2y2 (starting at prev. point) |
Graphics: Points, Bitmaps | ESC P xy (plot point), ESC DG[data] (download bitmap) |
Graphics: Full-screen Bitmaps (0-16) | ESC X# (store) ESC E# (recall) |
Configuration Instruction | ESC W# (write configuration bits to memory) |
