ai_ardulib_ssd1306's Issues

Example displays three lines overlapping?

Hello,

I found your library and wanted to use it as it seems much more efficient than the Adafruit libraries. When I try to run your example HelloOLED.ino, I am seeing the three lines displayed, but they appear to only be 2-3 pixels tall, and overlap each other. So I can see the top pixels of your company name, then the next line covering the rest, then only a few top pixels of the third line.

I'm using a 128x32 OLED display ... is there some other setting that I am missing?

Change Font for 128x64 oled

Hi, I'm using for Nrf51822 but the Font 8x8 and 5x7 is still small, i want to change 10x10 or 20x20, how can i change it ? Please give me a solution. Thanks

The documentation is down

Tried to look at the tutorial mentioned in the description and this is all i see

HelloOLED Compiling Error

If custom glyphs are added to the fonts, the putChar() won't display them

There is a test in putChar() to ignore non-printable characters. If custom glyphs are added to the font however, these will never be displayed unless the 127 is replaced with another value.

(This maximum should probably be derived from the font-definition some how.)

When using font5x7, clearDisplay only clears left side of the screen.

The culprit seems to be the loop that puts spaces on the screen for only 16 characters. The maximum here should probably be calculated from the actual font sizes.

Particle version

Is there a version of this that will compile for particle ide?

128x32 screen support

I am trying to get this to work on a 128x32 ssd1306 screen. The text makes it to the screen but is not displayed correctly. I'm assuming something in the .cpp file needs to be changed because I changed
#define SSD1306_Max_X 127 #define SSD1306_Max_Y 63
to
#define SSD1306_Max_X 127 #define SSD1306_Max_Y 31 in the .h file and it did the same thing. Any help would be appreciated.
