One of the goals of this board, aside from the CEC decoding, is to control a strip of WS2812 RGB leds to use with the Hyperion software.

The Proof of concept uses the RawHID mode/output of hyperion but there are a few issues:

On the master branch, Hyperion needs to be patched, to use the hid_write() function, and it works fine. It also uses on USB endpoint on the firmware.

On the usb_feature_rpt branch, Hyperion can use the hid_send_feature_report() function, but I get a lot of "Failed to write to HID device" and annoying delays. It doesn't use a dedicated USB endpoint, which is nice though...

The current implementation uses an hardcoded hardware address (on HDMI port 2 on my setup) which is really not ideal (since it forces the TV to switch channels)

It think it is possible to use the I2C lines to get the current HDMI port from the EDID.

Since the Atemga32u2 doesn't have any hardware I2C port, a software implementation is required.

Bonjour,
Je viens de prendre un adaptateur pour permettre le CEC entre mon televiseur Samsung et un Kodi installé sur un PC HP Elitedesk 800 G2.
L'adaptateur est bien listé sur la TV ( "ArkHome") mais connexion impossible. J'ai essayé en branchant sur toutes les sortie hdmi (1/2/3/4) sans succès.
Le modèle exacte de la TV est Samsung UE6B6000VW

Des pistes de recherche ?

Current software implementation uses an hardcoded map to match the Remote keypresses to keyboard keys. It probably only works fine on my setup (TV remote with Kodi).
The device name is also hardcoded

It would be better to have some configuration sequence/tool to let the users customize it for their usages.
Settings would then be stored in EEPROM.

A few options I think about:

• Interactive setup using the OSD feature
  • How to start the sequence ?
• Interactive shell/prompt using USB CDC Serial emulation
  • Doesn't require any special tool on the host computer
  • Requires 3 USB endpoints I think. The Atmega32u2 only has 4 (apart from EP0) , One is required for the Keyboard emulation. Another one is currently required for Hyperion (see issue #1 ).
• Custom config tool using RawHID Tx/Rx
  • Only two endpoints required
  • Custom tool is required on the host computer, which I would like to avoid
