Hi - I would like to add additional remote controls commands to my current configuration. I have a working configuration for my Nvidia Shield TV 2017, but I know there are other keyboard keys that aren't in the FLIRC GUI (primarily, the Android Menu and Google Search buttons). I have seen postings about HID codes and the FLIRC util. I have searched the forum, but I didn't find a consolidated posting that had instructions on how to identify USB keyboard codes and how to add them to an existing configuration with FLIRC Util. Is there an existing single posting with these instructions? If not, can somebody please post the step-by-step instructions here? I think other folks would appreciate it, too! Thanks! AzJazz
tl;dr USB HID codes from here http://www.freebsddiary.org/APC/usb_hid_usages.php should be given to flirc_util record_api as decimal Hi all Just had to deal with flirc_util record_api on account of the GUI not recognizing the Flirc board as connected (http://forum.flirc.tv/index.php?/topic/2208-linux-x64-flirc_util-works-without-root-but-flirc-gui-always-say-disconnected/#comment-12182 ), and I thought I'd save the information I found in a topic with a descriptive title for future reference: This is also a good resource: http://forum.flirc.tv/index.php?/topic/128-modifier-keys-in-command-line-recording/ flirc_util record_api x y where x is the modifier key and y is the HID key. # Modifier keys According to the documentation presented when running "flirc_util record_api" the modifier keys are specified by logically OR'ing these values together as binary (the de facto standard for specifying flags as a single parameter): OR'ing binary numbers is done by going through the two numbers bit by bit and comparing corresponding bits. If one of the two bits is 1 set the corresponding result bit to 1, otherwise set it to 0, e.g. 0101 OR 0010 = 0111. For these specific binary numbers (1,2,4...128 as decimal) OR'ing is the same as ADDing, and since "flirc_util record_api" expects a decimal input we might as add them in decimal: LEFT CTRL + LEFT SHFIT = 1 + 2 = 3 LEFT CTRL + LEFT ALT + LEFT SHIFT = 1 + 2 + 4 = 7 # HID keys The HID key codes can be found here: http://www.freebsddiary.org/APC/usb_hid_usages.php "flirc_util record_api" expects the code as decimal, but the freebsddiary.org page gives them in HEX, so get your hex-to-dec converter out. For example, 'g and G' is specified as 0x0A which is 10 in decimal. So if you want to program the g/G keyboard key with "flirc_util record_api x y" you have to specify y as 10, not 0x0A or similar. Another example is DownArrow which is specified as 0x52 in hex which needs to be specified as 82 in decimal. # Putting it together If you want to program LEFT CTRL + LEFT SHIFT + UP ARROW you need 1+2=3 as modifier key and 0x52=82 as HID key: flirc_util record_api 3 82 Another example is LEFT CTRL + LEFT SHIFT + LEFT ALT + S which would be 1+2+4=7 as modifier key and 0x16=22 as HID key: flirc_util record_api 7 22 # Documentation from flirc_util
