Hi,
I have finally published the library on CodePlex. You can grab it here http://microliquidcr...l.codeplex.com/
Basically the same code as previously published on my blog, just with few renames.
Please let me know if you have any suggestions on what can be improved.

Secondly the Fritzing wiring diagram on Szymon's blog page is slightly incorrect w.r.t. the SPI port:
SHCP = PIN 13 (not 12)
STCP = PIN 10
DS = PIN 11
Thanks for spoting this. In earlier version I sent data to shift register all in managed code, but later I switched to hardware SPI and thus had to move clock input pin to SPCK (pin 13).
Edit: I have updated the diagram in the blog post.

Hi,
The pin assignment looks exactly the same as one that I used. If you look at the diagram on my blog the pins on the LCD are numbered from right to left. Thus as you can see pin 3 is connected to potentiometer to adjust the display contrast. I use output pin 0 on shift register to turn backlight on or off so it should be reserved. Then pins 1,2,3 on shift register are connected to pins 4,5,6 on the display (rs, rw, enable). Finally pins 4 through 7 are connected to pins 11 to 14 on display. Because it uses 4-bit mode display pins 7 to 10 are not connected.
I hope this helps.

I'm glad that some of you found my library useful, and posted about your results:

I was thinking to put it on CodePlex so that we can keep a better track of all code changes and extensions. What do you think?
Should I keep the name MicroLiquidCrystal for the project?

Or just cheat and get a SerLCD from Sparkfun. ;-)
Meh, that would be no fun. Besides I didn't wanted to wait for the order ;-)

If you can afford it, I suggest the Rigol DS1052E. It has the bandwidth and sampling rate needed for most microcontroller project.
There was some hack to double the sampling rate to 100Mhz (but it no longer works with new firmware)
http://www.eevblog.c...100mhz-ds1102e/
I found it on http://www.dealextre...ls.dx/sku.30573
But what you think about this one? http://www.dealextre...ls.dx/sku.36153
If you are just going to look at digital signals, you can consider USB logic analyzer. There are a few companies that makes them.
I was thinking to buy this one http://www.saleae.com/logic/features/. Is it good enough?

Beta Firmware and Drivers
Does anybody from those who downloaded the firmware and possibly tried it have any feedback? How should I interpret the silence, with regard to initial eager requests? Please let me know whether it works or not with your device, so I can fix possible problems and publish the code. Thanks in advance.
Hi CW2,
I finally got to look at this. I uploaded your firmware and tested with one DS18B20 sensor. I'm happy to report that it works fine with your demo app :-)
Did you managed to implement the search function? I think this is the only important thing missing from the native code. I compare it to arduino version http://www.pjrc.com/...bs_OneWire.html
The Skip and Select methods can be implemented in managed code because it only sends a command with WriteByte. We can also compute the Crc.
I can send you my version of Micro DallasTemperature library if you want to test it.
Edit: Oh, and I would definitively move the managed OneWire class to another assembly (at least until it makes to official firmware). Having two versions of the same assembly totally messed my project references.
