GLO-216 2x16 Multifont Serial OLEDs
GLO-216 displays receive serial data at 9600bps and display it on a bright, high-contrast OLED screen in a range of four font sizes. With this display we've implemented just about every serial-display user's wishlist: high brightness/contrast, wide operating temp range, low power consumption, multiple font sizes, compact footprint, low cost, even two colors. Looking for a larger display with similar features? See GLO-416Y.
GLO-216 Features
- Brilliant OLED (organic LED) display
- Fits standard 80x36mm LCD footprint
- Four font sizes from regular 2x16 to huge 1x8 characters
- Accepts normal inverted serial or UART-direct noninverted
- EEPROM storage of startup screen, 16 custom characters
- Uses a superset of our terminal-style instruction set (BPP, ILM, etc.)
- Deep inventory for no-lead-time delivery

OLED Instructions
GLO-216 works like a mini-terminal, displaying text and responding to traditional control characters like linefeeds, carriage returns, tabs, etc. via a superset of the instructions used by our other advanced displays (BPP, ILM, VFD, SGX). GLO also offers four font sizes, and EEPROM memory for a startup screen and custom characters.
Control codes not listed below are ignored.
| Instruction (ctrl code) | ASCII | Hex |
|---|---|---|
| Home cursor (ctrl-A) | 1 | 0x01 |
| Select font normal→tall→wide→big→normal... (ctrl-B) | 2 | 0x02 |
| Set font to normal, default 2x16 size (ctrl-C) | 3 | 0x03 |
| Backspace (ctrl-H) | 8 | 0x08 |
| Tab: jump to next multiple-of-4 column (ctrl-I) | 9 | 0x09 |
| Smart linefeed: move down one row (ctrl-J) | 10 | 0x0A |
| Vertical tab: move up one row (ctrl-K) | 11 | 0x0B |
| Formfeed: clear the screen (ctrl-L) | 12 | 0x0C |
| Carriage return: move to start of next line (ctrl-M) | 13 | 0x0D |

ESC x 0 stores current custom-character set to EEPROM. |

Supported BPI/BPK Instructions
GLO-216 accepts a subset of BPI/BPK instructions (those not relying on scrolling, visible cursors, offscreen memory, or LCD-specific custom-character quirks). BPK/BPK instructions consist of an instruction prefix, 254 (0xFE hex), followed by one of the instructions from the chart below.
| BPI/BPK Instruction | ASCII | Hex |
|---|---|---|
| Clear screen | 1 | 0x01 |
| Home cursor | 2 | 0x02 |
| Move cursor 1 character left | 16 | 0x10 |
| Move cursor 1 character right | 20 | 0x14 |
| 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 |
