OLED 128X96 cheap china lcd

Hi Guys,

thank you for sharing your code.

I have 3 displays bought from the following selle on e-bay :

http://www.ebay.com/itm/0-96-128x64-...item1e649b61d1

I have one doubt :

What pins are you using for IIC connection ?

I can see :

SCL var PortA.3 ' I2C Clock PortB.4
SDA var PortA.2 ' I2C Data PortB.1

The RES is not necessary ? Should this grounded or connected to vcc ?

Thank you !

Regards,

Sérgio

Hi,
I've got one from that very same seller and I've tried to get it to work numerous times. First with code of my own then with code from this thread - no luck.

I've found that mine came strapped for 4 wire serial, which is the mode I tried coding for while I'm pretty sure that the code posted here is for 3 wire serial. I changed the solder straps on the display but no luck.

The datasheet for the controller chip has notes on what pins to use, not use, tie high or tigh low depending on which mode it's supposed to operate in.

Anyway, I've pretty much given up on it (mine is probably busted), if you get yours going I'd appreciate it if would post the details so I can give it a try on mine, thanks!

/Henrik.

Hi all,
In the code I posted I'm using the picbasic SHIFTOUT function nothing more or less very simple
SDA var PORTA.2 'pin 4 output
SCL VAR PORTA.3 'pin 5 clock
The above pins are assigned.
My display Has 3 junpers in the back mrked BS0,BS1 AND BS2. I solder BS2 , BS0 and BS1 are off.
When I started using this display I tried using I2C but with no luck then switched to SPI using SHIFTOUT.
SDA and SCL does not mean I'm using I2c just variables I created when I started hoping to use I2C but failed I never renamed them.
Hope this helps.

correction to the above:
BS0=1;BS1=0BS2=0.
Sorry.
Regards,

Joe

Sorry, the comment:

SCL var PortA.3 ' I2C Clock PortB.4
SDA var PortA.2 ' I2C Data PortB.1

Should read:

SCL var PortA.3 ' I2C Clock PortA.3
SDA var PortA.2 ' I2C Data PortA.2

RES is not necessary in my example as my display only has 4 pins.
