SSD1322 OLED Library to use with the Adafruit GFX/GrayOLED Library
License: BSD
Forked Oct 2023 by bringert from the venice1200 SSD1322 fork and modfied for an SSD1322 OLED with 128x64 resolution, and with a much faster hardware bulk SPI implementation. On an Arduino Nano 33 BLE, the full 128x64 display can be updated in 16 ms. Only tested with hardware SPI and a 128x64 display.
Forked in 09/2021 from the Adafruit SSD1327 Library (https://github.com/adafruit/Adafruit_SSD1327)
and modified for the SSD1322 Display Controller with 256x64 Pixel OLED Display Size.
Other OLED Resolutions and Interfaces (I2C,3SPI,6800,80xx) are currently (2021-09-14) untested.
Tested with the ESP32 and ESP32-S3 MCU and the SPI Interface.
Beside the Hardware specific modifications I implemented the function
[device].draw4bppBitmap(const uint8_t bitmap[])
to draw a 4-Bit Fullsize Grayscale Picture (256x64 Pixels, 8192 bytes) into the Display "Buffer".
You need to run [device].display() after this command to get the Picture shown.
Most Functions write the Data Bytes into the Display Buffer.
You need to run [device].display() to see the result.
| Function Name | Function |
|---|---|
| begin [1] | Init Display |
| oled_data [1] | Send Data Bytes to the Display |
| display [1] | Update Display Content/Copy Display-Buffer Data the Display |
| clearDisplay [1] | Clear Display |
| setContrast [1] | Set Display Contrast 0..255 |
| displayOff [1] | Switch Display off |
| displayOn [1] | Switch Display on |
| draw4bppBitmap [1] | Draw 4bpp Picture |
| invertDisplay [1] | Invert Display Content |
| setRotation | |
| drawBitmap | |
| drawXBitmap | |
| setTextSize | |
| setTextColor | |
| setTextWrap | |
| println | |
| write | |
| setCursor | |
| drawLine | |
| drawCircle | |
| drawRect | |
| fillRect | |
| drawTriangle | |
| fillTriangle | |
| drawRoundRect | |
| fillRoundRect |
Functions with an [1] are SSD1322 related functions.
The others are from Adafruit's GFX/Greyscale Libraries.
Succesful tested with "U8g2_for_Adafruit_GFX" https://github.com/olikraus/U8g2_for_Adafruit_GFX to get better text/font support.
GFX/Greyscale Library Notes
- The Library Command
drawGrayscaleBitmapis not usable for an SSD1322 OLED as they are for 8-Bit Displays. - The base font has his base on top-left, the additional font on bottom-left.
- The additional fonts don't overwrite themself even Text Color is set to (fg-color,bg-color).
❗ Work in Progress ❗
