Hi folks,

v0.07 is ready.

When those who are already building devices, get them working correctly,
v0.07 + any bugfixes becomes v1.0.

New Olimex order number: #AR161202

v0.07 - changes from v0.06:

* Changed R124 and R128 (optocoupler LED-current limiters) to 470 ohms.
* Programming connector is now standard 10-pin.
* Cleaned up the digital board layout.
* 5VI 5VO power pins removed in favor of a single power input.
* Bugfix: digital board outline cut open to preserve isolation distances.
* Bugfix: Diode moved out from under 7805.
* 10k trimpots changed to 20k
* Added decoupling capacitor near optocoupler on isolated side.

The fifth release contains mostly bugfixes in the partslist and the firmware. The design itself only saw one minor (non-critical) change.

Let's call this "release candidate 1". More information is available on the mailing list and in the release notes.

I found a chip from Arizona Microchip that will make adding IrDA support for our device really easy. It implements a lot of the necessary hardware and also some software protocol layers otherwise very complicated to implement.
