This is an old revision of the document!
LocalTalk BeagleBone Black Cape
Revision History
- 0.1
- Initial version
- 0.2 (not yet ordered)
- Switched to 10K pulldown instead of 100K pulldown for ISP command handler entry pin on LPC MCU. 100K wasn't enough.
- Added 10K pulldown to keep LPC MCU in reset until BBB explicitly asks it to start.
- Fixed mistake where I left A/!B channel selection pin floating on the SCC.
- Current known issues:
- The RX pins of the transceiver are wired to the TX pins of the Mini-Din-8 pinout, and vice-versa. I should fix this before ordering revision 0.2.
- Confirm that I got the polarities of the + and - pins correct – did I connect + and - to the correct pins on the transceiver?
