===== Alpha 0.4 Befehle =====
  - 115200 Baud
  - Monitor mode
  - Cano mode (default)
  - Cano classic mode
  - Ambrc mode
  - Register 'xxx'

===== Commandos =====

RCHourglass decoder can execute commands. A software configurator called RCHourglassManager is available for download here. The source of RCHourglassManager can be used as a starting point to port to other platform or to study the protocol.
To issue manual commands, a terminal program like PUTTY or Hyperterm can be used to connect to the COM port. NOTE: manual command does not have any feedback while typing, so you might want to type 'blind' or enable feedback in terminal options. When ENTER is hit, the command is executed.
Most of the commands respond with a line that starts with SUCCESS or ERROR Some commands (like transponder info) have multiple lines response closed by a SUCCESS line.

VERSION and LICENSE commands
Command
Description
Note
VERSION
Returns the current firmware version.
Example: RC Hourglass v0.5 beta
LICENSE
Returns the licensing terms.
Multi line response. Last line contains 'Marco Venturini'
Note that any derivative work MUST respond to LICENSE command with the same licensing terms.

Mode setup commands
The mode setup commands will make the decoder change the emulation mode of the current port until power off. These commands respond with an echo of the mode set (not a SUCCESS response)
Command
Description
RCHOURGLASS MODE
Extended Cano mode with hits, voltage, quality and temp reporting
CANO MODE
The decoder works in CANO emulation mode with decode of transponder number
CANO CLASSIC MODE
The decoder works in CANO emulation mode without decode of transponder number
AMBRC MODE
Emulation for AMBRC protocol.
MONITOR MODE
writes to serial every packet read by the loop, without any decoding. Useful to check circuit performance/issues.
TRANX MODE
Emulation of TranX protocol
LOOPBACK MODE
All traffic from the other serial is loopbacked here with character < for incoming messages and > for outgoing messages
NOTE for AMB emulation this is an emulation for AMBRC protocol. Passage records with number of hits and low voltage indicator are supported. This is to use the decoder with lap timing softwares that do not support CANO protocol. Low voltage bit is rised with a voltage threshold set in the decoder configuration

Startup mode setup commands
This command set the startup emulation mode for the two serial ports (USB and serial)
Command
Description
SET SERIAL [CANO : CANO CLASSIC : RCHOURGLASS : TRANX : AMBRC : OFF]
Set power on mode for the serial port
SET USB [CANO : CANO CLASSIC : RCHOURGLASS : TRANX : AMBRC : OFF]
Set power on mode for the USB port
GET SERIAL
Returns startup serial mode: SUCCESS GET SERIAL [mode]
GET USB
Returns startup USB mode: SUCCESS GET SERIAL [mode]

Time commands
Command
Description
GET TIME
Return the curent time of the decoder in quarters of ms
SET TIME [t]
Sets the curent time of the decoder in quarters of ms. [t] is in hex
Example:
GET TIME
Response
SUCCESS GET TIME 00075A06
Current time in quarter of ms = 0x00075A06 = 120.449 seconds
To set the same time:
SET TIME 75A06

Transponder management
The RC4 transponders can be detected only after they've been registered in the decoder memory. RC4 Hybrid should not need registration.
As for version Beta 3, a maximum of 40 transponders can be kept in the memory and persist even in case of power disconnection.

How to register RC4 transponder
Place and stop the car above the wire.
The blue LED on the PSOC board should be well lit.
Avoid any other car passage. Issue the command REGISTER tx number, for example REGISTER 3462137
The decoder will start learn and return success or failure. In case of failure, reposition the car and/or check correct loop connection.
In case of success, the 12 most important 'packets' of the transponder are reported, with the number of hits for each one.
A minimum number of hits above 30, with the maximum above 100 is a very good target.
The registration can use a nickname for the transponder, like REGISTER 3462137 MARCO. The nick name will appear in the list of registered transponders.
The last option is to make a transponder 'important' that is it's never going to be 'kicked out' of the memory if the limit of 40 transponders is reached.
Important transponders can be only deleted manually. When the memory is full, the oldest non important transponders are deleted to make room for the last registered one.
For example, to register yours as an important transponder, write REGISTER I 3462137 MINE where MINE is the optional nickname.
Learn process can be interrupted with the ABORT command, but it will timeout if no transponder is detected.
The LIST command will show the registered transponders.
The DELETE tx number, for example DELETE 3462137, will remove a transponder registration from the decoder memory.
The INFO tx number, will show registration informations for a specific transponder.
This commands are made to backup on the computer registration informations.
Flashing a new firmware will EREASE the registrations done.

Configuration, beeper and led management
Command
Description
GET LED
Returns SUCCESS LED [duration]
SET LED [0-255]
Sets led notification in ms when passage is detected. Duration 0 = no led notification.
GET BEEPER
Returns SUCCESS BEEP [duration] [divider]
BEEP
Emit a beep
SET BEEP [0-255] [0 or 6-30]
Set beep notification in ms when passage is detected. Duration 0 = no beep notification. Divider sets beeper frequency: 0 is only pulse, otherwise frequency is 20kHz/divider, where divider must be between 6 and 30 
GET ID
Returns SUCCESS GET ID [0-255]
SET ID [0-255]
Sets decoder ID
GET VMIN
Returns SUCCESS GET VMIN [0-255] where the number is voltage threshold in 1/10 of volts
SET VMIN [0-255]
Set the voltage threshold to actiate low battery warning voltage is value divided by 10. 0 = no warning. Max Voltage = 25.5V
NOTE a 50 ms blank time is always inserted in case of multiple close car passages.

PIC programming commands
This commands require the optional components of the schematic to allow direct PIC programming.
WARNING Do NOT connect unsupported PIC models or LF PIC models. The voltage might destroy the component.
Command
Description
DETECT
Returns the model ID of pic in the programming socket
BEGIN PROGRAMMING
Begin PIC programming
ERASE DEVICE
Erase pic in socket. Must be in program mode
WRITEMEM [V] 
Write PIC memory at given address. [V] option is to verify written data. Address is in HEX ASCII. The Data is expressed as sequence of max 10 words each one expressed with 4 ASCII character. PIC programming must be started before writing memory
END PROGRAMMING
End PIC program mode
ABORT
Ends programming or RC4 learn
DETECT response is multi line. The last line is SUCCESS PIC MODEL NNNN where *NNNN is Hex part number ID. A value of 3066 sould be reported for PIC 16F18313.
