I wanted to know if it is possible to use oled to change expression Robonova
Example
hattack = hard
Dances = smile
Yes.
It all depends on how you decide to physically connect to your oled.
I'm still dabbling with learning how to program the display, but will probably use a serial UART spin object. I could then send commands (byte at a time) to the oled using the robobasic ETX command.
You could also try i-bot's i2c flash upgrade to create a I2c link....?

I uploaded my simple spin code to emulate the LCD display.

It supports PRINT, FORMAT, HEX, BIN, CLS and LOCATE.
Note: You need to put a resistor (1.5K) in the LCD signal lead due to the different logic levels.

I have just set mine so I can call up a 24 bit .bmp file from the SD card from RoboBasic.
It needs 24 bit per pixel .BMP files at 96 * 64, and is a bit slow, but nice to see a full graphic face at last.
Now have identity crisis between Shrek, Kryton, Holly, and my Dog.
Let me know if you want to try it, or better still if you can speed it up.
Maybe someone can make it just change the pixels to change expression.

Hi my Oled has finally arrived
Can you give me the scheme your connection with robonova?
For connection for use as LCD connection resistance 1,5K
How can I connect microphones?
and I would be you thankful if you give me the software to recall images face with robobasic
Thanks and excuse me if I ask so much but I feel like immediately using oled and to begin to learn language planning
thanks

Check out the propeller demo board, to see how to connect an electret mic, it looks like it will use two of the four spare pins?

PS I had the following circuit connected to my RN's "ears", but i had no luck with it, I think they were too close together: (they are currently not connected). I don't know what to do to get them to work??

This technique is designed for full scale humanoids where the distance between sensors, mounted in the same plane, is large enough to provide an easily worked waveform differential. The same holds true with optics and lenses, as the separation reaches an optimal plane distance of several inches for stereo optic results. The sound software could be modified but at such close separation distances, the differential would be minimal and not product accurate results. It would be more beneficial to place these sound sensors at opposite sides of the robot in different locations. This can optimally locate sound point sources with sensors mounted at small differential locations on the humanoid. As an additional tweaking, collection ears can focus the sound waves and produce directionally tuned results. If you don't mind placing the stereo-acoustic sensor in the front, back or sides, it can improve the results substantially.
