hello all, i have seen and used code for the imp using the libraries for ssd1306 oleds. I found some cheap oleds ssd1306 compatible on ebay and got one, but cannot drive it. It is missing the reset pic. they have vcc, GND, sda and scl.
here is an example: http://www.ebay.com/itm/291341369509?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Any idea how to drive this thing? or anybody have any code written already for it?
Thanks!
I presume it auto-resets when power is added, so you can either remove the reset pin parts from the driver code, or if you think you’re going to want to reset the display during runtime, drive the display’s VCC from a imp pin set to DIGITAL_OUT. Write 1 to that pin to power the display, or write 0 to switch it off. That’s what I’d try first.
sounds good i will give it a try and let you know
thank you
the code actually works in these LCD’s as well. Thanks very much!
nice! it would be cool to see your improvements to the Code.
I actually didnt do any improvements. I only connected it without using the reset line. and it worked. I think the first time when i tried it it didnt work because my power line 3.3V was not properly connected. As a matter of fact the adafruit OLEDs that have a reset line, also work without driving it… Which is nice, cause i save an extra pin on the imp
