SSD1322_for_Adafruit_GFX

SSD1322 OLED Library to use with the Adafruit GFX/GrayOLED Library

License: BSD

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.

Working/Tested functions:

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
print
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 drawGrayscaleBitmap is 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 ❗
