I have updated Adam's "peeks & pokes" in the files sections. This is based on tracing out the various signals from the CPU. pix of the unused GPIO access...
Ken, would you mind looking at the SSI ports when you get time. i suspect that the SSI1 port is what is being used for the i2c communication, but i'd like to...
Ken, ... hmm, thats a bummer! i was hoping that the SPI ports were brought out and could be used. oh well, back to plan b, bitbang spi with some gpio's. ...
These look like great little devices, especially with the backlight mod. I am thinking of buying one for myself but I have a few questions first. I remember...
Zipit AC adapter: 5VDC at 0.6A Tip + Ring - ... From: zipitwireless@yahoogroups.com [mailto:zipitwireless@yahoogroups.com] On Behalf Of Patrick Sent: Tuesday,...
Hello All! I've been playing around with the OpenZipit firmware from the files section and I was hoping that someone could answer two questions for me..... 1)...
As of yet, I have not purchased one of these, but it will happen soon, but before I take the big step, I'd like to ask people that are out there, actively...
Hello all, I just got a zipit and was wondering what the simplest way was to add ssh into the ramdisk image. With ssh, you could remote into a server and...
First off, you need to be using the zimage.dat, and ramdisk.gz from the OpenZipit files section. The ZipitPet images do not have the dynamic libs, the proper...
I have traced out the connections to the LPC915 microcontroller. It seems that this part has a role in many parts of the Zipit. Luckely, it seems happy doing...
... Check! ... Hummm... I see that they have different minor device numbers.... what are the differences? ... Aha! After a few quick insmod commands I'm all...
<snip> ... That's just how I did the driver. This was a learning experience for me, so I may not have followed the "approved way" to do anything. But the...
Hey everybody! Just got my zipit and I found you guys! I've tried to find this answer both on the web and on this group. Has anyone successfully modded their...
... Not AFAIK, but it depends on the kind of "memory" you mean It would be difficult to add more RAM or Flash ROM on the main board (BGA packages). IMHO there...
Thanks for taking care of the update, Ken! I notice the following interesting coincidence: based on your map of the LPC915, it appears the extra pins near the...
This seems like it might be useful to some of the more electrically inclined at this sight. Then again, this may be info that people already have and it's not...
When I removed the SDRAM and Flash from the "dead Zipit", I did not pull up or damage any traces. Take a look at the picture in the photos section. I did not...
I'm going to guess (without looking at the datasheets) that the larger chip requires more address lines (to address a larger amount of memory) and that even if...
Hey deepfriedcereal, I'm no EE either, but I have been doing Operating Systems/ embedded firmware for a couple decades. I've worked closely with EEs and...
The MX29LV320AT/B is the next density up from the Zipit's MX29LV160AT/B. The increased capacity is achieved by using ball D3 for Address A20. This is a NC on...
Hi In the development board they also had serial port traces that were removed in the production boards leaving us to solder to ends of surface mount caps and...
Could you, andrew.hakman, or someone else who has more knowledge than I do actually look at the datasheets to make sure? This mod may be worth nothing to you,...
Thanks Ken and Tommy for the encouraging replies. Thanks to Andrew for your response, too. I think 4MB of flash ROM is obviously better than 2MB for those...
I think SD or MMC is a serial protocol, whereas this is a parallel chip sitting on a data and address bus. Someone else is currently looking into SD or MMC,...
I am wondering on the current situation of the kismet port. Has anybody been working on this lately? Does anybody have any guides on porting software to the...
I think what you want to do via ssh would be accomplished by mounting a remote filesystem like nfs (tuneled through SSH if necessary) and pull the kismet...
Kismet offers a drone mode where a remote sensor runs as a remote daemon, but unless I'm missing something, I can't see how the same wireless interface could...
