OLED SSD1306 128 x 64 (cheap, common (China) 0,91" I2C )

[PE1DDA]

Hi Guido,

Amongst fellow uSDX'rs I found troubles with my OLED's 1306 if I do not adapt the latest (since november 22) "m" firmware: line 687: #define BRIGHT 1 ( must be un-comment) and/or line 699: 0x81, /32/ 0x7F, // Set contrast control register to: 0x81, /128/ 0x7F, or: 0x81, /64/ 0x7F,
However with (much) lower brightness if # define BRIGHT 1 is commented Furthermore some characters, like the ones used in the uSDX banner and VFO a / b indicators show up unreadable / unrecognizable. Personally: I do not like the "line printer, interlaced characters" that show up on the OLED, knowing that it can be beautiful sharp (and even display 5 very good readable lines) I found a SSD1306 library (maybe you know it already) with fast I2C :

and used it to very simply replace code for an LCD 2004 in an Arduino SWR / PWR meter project and even succeeded in putting more information on the display. Please check if this library could make things easier for the OLED driver impact (and nicer for the looks :-)
