Pix Packet Protocol

    #A
    #C

    msgOut = """
    #S +
    #M +
    #E +
    #P +
    #X"""

    #where
    #A is the letter "A" meaning "16 byte packets (pktSize)"
    #C is t100c  (100 character time delay: "roman numeral C")
    #S is SOM: "["
    #M is Message text to be sent including a prefix of "16" (will be followed by EOM)
    #E is EOM: "]"
    #P is the padding characters (enough EOMs to fill the packet)
    #X is t10c  (ten character time delay: "roman numeral X")

    #Most messages will have   msgOut = "AC" "SMEPX"

"[16Hello,JoeMaxR"
 1234567890123456   #facilitates counting the characters (not transmitted)
"oyBob]]]]]]]]]]]"

All ASCII characters are permitted in the message except "?".
Packet Lengths are small.  This favors an interactive Ascii protocol. 
All ASCII messages are readable by humans, including the "control" 
characters: "[" & "]" in the message character count.
The only 7-bit ASCII character NOT allowed in message content is "?".
The timing can be adjusted to facilitate human testing.
Little or no message encoding/decoding is required if "?" is avoided.

Issue 01: When transmitting, the 3rd "o" is missing when sending "Hello,JoeMaxRoyBob".
Issue 02: The prefix "[16" was included in the message in version A, but keeping the msg 
             len at 16 (counting the "[" and the "]" as message characters).
             This is desired!! But the "[16" is contained only in the first packet.
Issue 03: The length of the message does not accompany the message.
             A parity bit can be included in every byte of the message.
Issue 04: No "?" characters are allowed in the actual incoming message.  This constraint will 
                     eventually be relaxed.
             This is a quick (and dirty) solution for eliminating any "]" in a message
             When encoding, every "]" is converted to "?". 
             When decoding the message, the prefix of "[16" will be removed.
             When decoding the message, all "]" at the end of the message are removed.
             When decoding the message, every "?" is converted back to a "]".
Issue 05: See Article 177 which should suggest processing the outgoing message to encoding every
             "/" into "//" and every "[" into "/S" and every "]" into "/E" instead of prohibiting any "?".
Issue 06: How to delete (uncreate) the machine Obj??  Is such a function necessary?
Issue 07: This "Pix Packet Protocol" differs from and is much simpler than the USB protocol.
Issue 08: Within each packet, the prefix "[16" and at least one suffix "]" is necessary.
Issue 09: The control functions to be used will be (hopefully) easily converted into 
             control functions similar to those of both the pico and the Raspberry Pi 5B.
             For now, they only work for the pico.  The full list of its functions follow:

             Control functions are:
                 Obj=machine.uart()  #Obj oop class object creation
                 Obj.any()           #Obj method  returning True or False
                 Obj.read()          #Obj method
                 Obj.write()         #Obj method
                 ????                #Obj deletion (not needed)
             Non-control IX functions are:
                  bChar() na
	          mpyRead()
	              Obj.any()
	              Obj.read()
	          serRx_pico()
	              Obj=machine.uart()
	              mpyRead()
                  serTx_pico()
                      Obj=machine.uart()
                      txParse()
                  show() na
                  testTx_pico()   #main
                  testRx_pico()   #main
                  txChar() na
                  txParse()
                      sendThisPack()
                          Obj.write()
                      sendLastPack()
                          Obj.write()
             End of function list

To be able to receive the packets, it became clear that interrupt software would be required. . . .

The use of globals is described in Article 174.  The code for the following functions is
included in global_and_isTypeStr.py. See Source S174:04 for the code.  These functions 
are mentioned in Article 174:

Future Plans

RPi 5B Issues

1. RPi.GPIO would not (maybe never) be supported on the RPi 5B.  Many of his electronics-related projects made use of RPi.GPIO.
2. Many Python programs would need a relatively new virtual environment for them to run.
3. Making use of the PCIe connector/interface was delayed because of the non-availability of a relevant "HAT"
4. The RPi 5B would require the latest version (Bookworm) of the 64-bit OS. New OS versions can be worrisom.
5. Raspberry had introduced a brand new RPi1 chip to control many of the communications channels. It could really
mess things up . . . or improve things
