- Charlieplexed errings
- Fast iteration
- Lohr-a…LoRa…get it?
- LoRa
https://www.youtube.com/watch?v=eIdHBDSQHyw
- Started in January 2024 with discussions with mustardtiger / Frank
- Charles had done Wifi long range before
- Also FM from ATTINY85
- Ethernet + AM
- Radio signals without radios
- USB
- Harmonics
- LolRa
- Upchirps / downchirps
- 903.825 – 903.975 mhz
- Michael Ossmann talk
- LoRa doesn’t do code matching
- JP Norair talking about LoRaWAN / DASH7
- Tool / emulator for the airwaves
- 3 lines of the repo
- Tool to create tables
- There are two 2 lookup tables (up and downchirps)
- Table is different for differnet spreading factors and base frequencies
- Andreas Spiess LoRa/LoRaWAN distance attempts
- Spreading Factor — can’t past SF10 on this setup for unknown reason

- Porting examples for the parts using the technical reference manual
- MNIST database – handwriting recognition system
- Announcement post on CNX about the new parts
- It’s possible to hook up parts directly through the 1 pin SWIO, so you can hot-load firmware
- Writing code onto a “scratch pad”
