Picture 4-5-4 Remote coded query
n Figure 4-5-
4, we can see the values of Ir Code “0x45” and keyname
“1”, where “0x45” is the code of
a button on the remote control and “1” is the name of the button function of the remote control. The total
encoding value of the supporting remote control is shown in Figure 4-5-4.
