CW and Voice memory keyer for ICOM IC-7300

After a long time I decided to came back to CW.

Just for fun and to use the Pandemia holiday I thought will be interesting to have a little remote for the Voice and CW memory.
While the Voice memory callback is relatively simple with CI-V protocol, for CW memory there are no commands provided by ICOM.
Therefore, the keyer will store the preset messages (10 messages) and send them using a 4 x 4 keypad.
The uC of choice is an Arduino with Atmega 328 on UNO platform.
The keypad is also used to Power On and OFF the radio and TUNE the ATU (I use an AH-4).

The 4 x 4 keypad is able to send: -In CW, 10 preprogrammed CW messages, each of 128 bytes; -in SSB, AM, FM, 8 prerecorded voice messages -"A" is Power ON -"B" is Power OFF -"C" is TUNE

Here is a small video on youtube about this

Here is the code:

Triggering preset Voice memories and CW Memories on IC-7300

1. Voice memory M1 - M8

The PC send to the radio the following:
$FE $FE $to $from $28 $00 $## $FD
## - Memory Location

2. CW Memory M1 - M8
It cannot be sent directly by a dedicated command via CI-V. (found it hard way, confirmed HERE)
Therefore, a workaround can be done like this:

1. Read the memory by sending
$FE $FE $DEV $RADIO $1A $02 $## $FD (## 1 to 8)
 the radio will respond with byte string 
$FE $FE $DEV $RADIO $1A $02 ____ 70 bytes $FD

2. Load the bytes into an Array
      Mem1[77] ; The Array will have 6 bytes preamble, 70 bytes message, 1 byte STOP BYTE (EOM)
3.  For (int i = 6, i<=76, i++)
    { byte CW = Mem1[i];
       This will send the stored message.

ICOM CI-V IC 7300 commands

Here are some finding:
-All end on $FD

Send CW characters 

 "A" - 41

Tuner On/Off

1C 01 00 - tuner OFF
1C 01 01 - tuner ON
1C 01 02 - TUNE START

Delta TX On/Off


BCD format / LSB first
Ex: $21 $00 $08 $13 $01 is dTX -1.308
