The StrichLux IO-ETH module will provide 1-4 universes of input or output via Art-Net initially, but may support other protocols later. This module can "take over" adjacent channels if configured to, so that only one module is needed for a complete StrichLux system.
Project Status
- 2013-09: Used for the LED wall display at Maker Faire Toronto 2013. One box failed in use, seems to be soldering on the PHY. Need to redesign this a bit to get rid of the QFN'ed PHY.
- 2013-05: On hold for how due to too many other paying/deadlined projects. Will resume when working on invisibleMaze.
- 2012-08: Used at BRC2012 in Beacon4, worked as-expected except that all boards were programmed with the same MAC address! Need to get dynamic configuration via CORE, as well as get the status display code written and working.
- 2012-07-21: Built a bunch more for the Beacon4 project.
- 2012-07-08: All working! :)
- 2012-07-01: Status LED driving code written, as well as code to do the initialization handshake/negotiation with the CORE. Will test it all tomorrow at the lab.
- 2012-06-29: After numerous software fixes, the board works! Now receiving ArtDmx packets and sending SPI. A few more tweaks required, then integration testing with the StrichLux/CORE.
- 2012-06-27: Borrowed a dev board from Andrew to confirm whether hardware or software was the culprit. Now have node discovery (ArtPoll/ArtPollReply) functionality working on the dev board, Lightjams successfully discovers the node. Hardware investigation will have to be done next time I'm at the lab.

- 2012-04-24: Started initial planning.
Specs
- Based around the PIC32MX664F128H microcontroller as there is no economical way to do Ethernet on FPGAs for low-cost designs
- This micro has no EEPROM (?!) so will need external I2C EEPROM for storing config data
- Using one with a MAC address burns in solves the problem of needing an IAB too
- Also needs external PHY
- LAN8720C is supported, small, and inexpensive, so it seems a good choice
Rev. 1 Issues
- Ethernet termination resistors are shown as 75 on the schematic, but (correctly) 49.9 on BOM
- C5 is under the crystal!
- LED display common wired to GND, but it's a common anode unit (can switch from ACSA to ACSC model until the board gets redone)
- Main status LED is backwards (anodes to GND, cathodes to PIC pins)
- Ethernet jack LEDs are backwards
- Hugely labour intensive to assemble, need to switch to using resistor packs wherever possible
