ni hao and hello OpenMoko friends, Ok, to explain my interest quickly: what I hope to do is to take an openmoko and add an E-Ink display, possibly replacing the LCD if necessary. It is too early for this to be useful to people so I do not want to consume any significant time or effort from OpenMoko's developers. I'm willing to do this on my own.
I'm the author of the E-Ink display controller drivers in the mainline linux kernel, and have been working on making broadsheetfb, the driver for E-Ink's latest controller behave in a way such that generic Linux applications can run on it without any modification. I have had some good initial results which I have shown. eg: videos here ( mozilla fennec on e-ink, http://www.youtube.com/watch?v=k4WBdagDgSg ) and various articles here ( http://highlycomposite2.blogspot.com/search/label/e-ink ). I feel I have a clear idea of how to achieve this idea of adding an E-Ink panel to a phone, the only constraint is that I need 22-pins of GPIO. I asked Harald and he had suggestions and pointed out that the 22-pin constraint may be a serious problem. I'm willing to sacrifice certain other peripherals to get that count. I was searching the openmoko wiki for GTA03 gpio pinout or some idea of a list of signals that are brought to surface pads or traces that I could then tap onto. Is this available? I had also looked at GTA02 pins: https://svn.openmoko.org/trunk/doc/hardware/GTA02v4/gpio.txt based on that, some notes for myself: - abandon bluetooth 1 - abandon sd card 6 - abandon LCD and repurpose those LCD's interface pins that can be repurposed as gpio, i think this gives me about 5 pins but not sure if all are brought to connector (lcdvf0,1,2, lcdhclk, lcdpwren), - so insufficient gpio. have to use gpio extender connected via i2c or uart. a big latency penalty though. - so look at gta03 and hope for inspiration :-) Any advice and suggestions would be greatly welcome.
