Byte2 and Byte3 follow the same pattern as above for the hotkey configuration. To
select any one of the key as hotkey, the bit value is set to ‘1’.
Description:
To configure an RC hotkey two bytes are required. The first byte is used to specify the
RC address and the second byte is used to specify the hotkey command. Hence
there is the option of having 8 hotkeys from the same RC address or one hotkey each
for 8 different RC address.
byte1, byte2: RC hotkey1
byte3, byte4: RC hotkey2
byte5, byte6: RC hotkey3
byte7, byte8: RC hotkey4
byte9, byte 10: RC hotkey5
byte11, byte12: RC hotkey6
byte13, byte14: RC hotkey7
byte15, byte16: RC hotkey8
If less than 8 RC hotkeys are required, there is no need to fill all the 16 bytes. The number of
configuration bytes sent will depends on how many hotkeys.
For example, to configure 2 hotkeys from 2 different RC addresses for Philips RC-5 protocol:
Philips RC-5 Device Address: XXX00001, Hot Key 1: XX000001
Philips RC-5 Device Address: XXX01100, Hot Key 2: XX000010
Note:
For RC protocols, where the MSB does not end on the 8-bit, the data is configured starting
from b0 (LSB) to the MSB.
