BPI-216 Two-line by 16-character Serial LCDs
BPI-216s are supertwist 2x16 LCDs with a low-power serial interface factory installed. The LCD displays text received serially, and a simple instruction-prefix mechanism formats the screen. Available in LED-backlit (BPI-216L) and non-backlit (BPI-216N) flavors.
BPI-216 Features
- Lowest current requirement: 2-3mA for non-backlit version
- Simple to use with easy programming/formatting
- Standard 80x36mm LCD footprint
- Deep inventory for no-lead-time delivery

LCD Instructions
Text sent to the BPI-216 prints to the LCD screen. Instructions for clearing the screen, changing the print position, etc. are distinguished from text by the instruction prefix, ASCII 254 (hex 0xFE). The byte after the prefix is processed by the LCD as an instruction. After the instruction byte, subsequent bytes are understood as text until another instruction prefix is received.
| LCD Instruction | ASCII | Hex |
|---|---|---|
| Clear screen | 1 | 0x01 |
| Home cursor | 2 | 0x02 |
| Blank display (retaining data) | 8 | 0x08 |
| Hide cursor | 12 | 0x0C |
| Show underline cursor | 14 | 0x0E |
| Move cursor 1 character left | 16 | 0x10 |
| Move cursor 1 character right | 20 | 0x14 |
| Scroll 1 character left | 24 | 0x18 |
| Scroll 1 character right | 28 | 0x1C |
| Set display address (position cursor) | 128+addr | 0x80+addr |
| Move to leftmost character of 1st line | 128 | 0x80 |
| Move to leftmost character of 2nd line | 192 | 0xC0 |
| Set character-generator address | 64+addr | 0x40+addr |
