adafruit OLED-Display do not want showing my data.

avoid · Jul 12, 2014

i try to get an "SSD1306 0.96" 128x64 OLED" display from adafruit works with an PICAXE.

the thread (http://www.picaxeforum.co.uk/showthread.php?23134-Aggravating-OLED-display)
was an help to get the right i2c adress and initialize to see anything on it.

but it seems that only the commands work.
it reacts not to data.

what can i do?

that's my example code.

Code:

#PICAXE 20M2
setfreq M32
dirsC=%11111101           ;make C.1 input(C.1 is decay mode)

pause 1000
