(Firmware only release; hardware 1.3x is still current.)
16n 2.1.1 is a point release that adds some tiny features:
- enforces a fractionally longer delay between the multiplexer being switched and the next analog value being read
- forces a send of CC data to the editor approximately a second after the board is connected to the editor.
- renames
firmware/_16n_faderbank_firmwaretofirmware/16n_faderbank_firmware, because the Arduino 2.0 IDE doesn't like a project that begins with an underscore. (This has no effect on the firmware)
As usual: if you are upgrading from version 1.3x, this is a breaking change. When first installed, it will overwrite any configuration on the device, and the configuration will then need applying through the web-based editor (https://16n-faderbank.github.io/editor). The configuration should persist between all subsequent updates.
Recommended best practice for installation is to use the attached .hex file directly with Teensy Loader. Instructions are on the wiki. Only compile your own firmware if you know what you're doing, and have specific hardware deviations from the norm you need to account for.
If you have a Teensy 3.2, 16n_v211.hex is the firmware file you want. If you have an LC, 16n_v211_TEENSYLC.hex is what you want. If you don't know what you have, ask whoever you got your 16n from.
