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
- 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.
- 2012-06-23: Link obtained after many code fixes. Still no data transfer working.
- 2012-06-22: Another evening of testing, found issue (worked around) with the display, fixed many software issues, but still no Ethernet link yet. Suspect (after I left the lab) that a missing SYSTEMConfigPerformance() call may be the culprit.
- 2012-06-21: PCBs and parts are here, assembled the first board. No time to test, will have to do that tomorrow. Firmware is ~10% complete.
- 2012-05-27: Routing done, checklist run, CAM processing done, sent off to MyRO for PCB manufacturing. Still need to order parts.
- 2012-05-26: Schematic/BOM complete, routing starting.
- 2012-05-25: Started schematic.
- 2012-05-01: Renamed from IO-ArtNet to IO-ETH, as I may support ACN or other protocols later.
- 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)
