FM Frequency Direct
0000 x10kHz (ex 87.50Mhz :0x222E,100.00Mhz:0x2710, 108.00Mhz:0x2A30)
Here are some examples:
Start
Code
0xFF 0x02 0x04 0x84 0x0A 0x28 0xAA 104.10
0xFF 0x02 0x04 0x84 0x0A 0x24 0xEA 94.50
0xFF 0x02 0x04 0x84 0x0A 0x23 0x5A 90.50
If the direct FM frequency is 104.10
1. Remove decimal from decimal number (10410)
2. Convert to decimal 10410 to HEX (0x28AA)
3. Send word as two bytes 0x28 0xAA in the last two bytes of 4 byte data
Others:
