7. EXAMPLE
1) PC control SE500, key command = key_take= 0fh
a.) The command stream = F0h,32h,0eh,05h,01h,0fh,,30h,34h,ffh
Header=F0h
ID=32h
Length = 9 bytes=09h
Command group=05h
Command mode=normal control code=01h
Control key code=key_take =0fh
checksum= (f0h+32h+09h+05h+01h+0fh) = 40h
checksum_low =00h+30h = 30h
checksum_high=04h+30h = 34h
END =ffh
b.) SE500 return data,
The return data stream =
Fch,32h,11h,05h,00h,01h,10h,00h,07h,41h,42h,01h,00h,20h,30h,30h,ffh
Header=fch
ID=32h
Length = 17 bytes=11h
Command status=05h
Error code =00h
Busy flag=01h
Effect mode & speed=fade +speed_2=00h+10h=10h
Effect No. =00h
Background color & border =white + border off =07h +00h=07h
LED1=41h
LED2=42h
LED3=01h
LED4=00h
LED5=20h
Checksum = (fch+32h+11h+05h+00h+01h+10h+00h+07h+41h+42h+01h+00h+20h) =x00h
checksum_low =00h+30h = 30h
checksum_high=00h+30h = 30h
END=ffh
