====== RCHourglass Zeitnahme ======

===== Schleife =====

Rausfinden wo die Fehler entstehen.

Niedrige Qualität kann schon plausibel sein. Jede 2. Message ist RC4, von 4 RC3 Message ist eine eine Status Message.

Mit der Länge spielen (verkürzen), sollte mehr als 1 hit ergeben. Quality is max 60% für RC4.

Schaltung relativ unabhängig von Schleifenlänge, 3×0,3 m keine Jumper. Wenn kleiner dann erst Jumper verwenden

Notfalls neuen Loopamplifierer mit Lm319

Oder mit breite der schleife spielen

Induktivität der schleife messen geht mit Transistortester nicht. Sollte so bei 20…100µH liegen.

Loop amplifier simulieren

C anspassung an schleife, nicht auf amplitude schaun sonder wenn der shift passiert.


===== Transponder =====

180° PSK

99bits in einer Message entspricht ungefähr den 24 Hex Werten in Monitor mode

200ns Periode


===== Transpondersignal Preamble: =====

<font 11pt/Calibri;;inherit;;inherit>F916 - RC3 oder z.B. 7916 erstes Bit wird nicht bewertet</font>

===== Protokol =====

Transpondernummer + ms viertel (hex)

Decoder protocols

RCHourglass can use different protocols to send passages information to the lap timing software:

  * <font 12pt/-apple-system;;inherit;;inherit>Cano/Cano classic protocol derived from original Cano decoder</font> * <font 12pt/-apple-system;;inherit;;inherit>RCHourglass protocol, similar to Cano protocol, but passage informations have some extra info like number of hits/quality/voltage/temp</font> * <font 12pt/-apple-system;;inherit;;inherit>AMBRc serial protocol</font> * <font 12pt/-apple-system;;inherit;;inherit>Tranx serial protocol</font>

 \\ <font 10pt/-apple-system;;inherit;;inherit><font 12pt">nnnnnn is an ASCII HEX string that represents the transponder number.</font> * <font 12pt/-apple-system;;inherit;;inherit>tttttttt part is an 8 character ASCII string representing the passage time in quarters of milliseconds from decoder startup.</font>

Example record

23E35500075A06

Transponder: 0x23E355= 2351957

Time in quarter of ms = 0x00075A06= 120.449 seconds

The RCHourglass protocol passage record is 25 characters long in the format nnnnnntttttttt-idhhqqvvtm

The first 14 characters are the same as Cano protocol.

  * <font 12pt/-apple-system;;inherit;;inherit>id the decoder ID (part of the decoder setup)</font> * <font 12pt/-apple-system;;inherit;;inherit>hh the number of hits received from the transponder</font> * <font 12pt/-apple-system;;inherit;;inherit>qq quality indicator of read (0-100%).</font> * <font 12pt/-apple-system;;inherit;;inherit>vv voltage in 1/10 of V</font> * <font 12pt/-apple-system;;inherit;;inherit>tt temperature (+100 °C offset)</font>

All numbers a ASCII Hex.

Example record

23E35500075A06-01152A3787

Transponder: 0x23E355 = 2351957

Time in quarter of ms = 0x00075A06 = 120.449 seconds

Decoder ID : 0x01

Hits : 0x15 = 21 hits

Quality : 0x2A = 52%

Voltage: 0x37 = 5.5V

Temperature: 0x87 - 100 = 35°C

NOTE Temperature and voltage info are read only from RCHouglass transponder firmware to be developed. Values are 0 for measure not available.

<font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Decoder ports</font>

RCHourglass decoder has two serial ports. One is USB-emulated, the other is on PSOC pins 12[6] and 12[7]. This second serial port is available also as a USB emulated COM on the KitProg half of the development board, and can be used to interface other hardware without USB ports/drivers.

Each serial port can be configured to use a different protcol. Serial port (not USB) uses 57600 8,N,1 data rate.

CommandReference

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Decoder commands/operations</font>

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.

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>VERSION and LICENSE commands</font>

|  \\ 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.

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Mode setup commands</font>

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 <font inherit/inherit;;inherit;;inherit>every</font>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 <font inherit/inherit;;inherit;;inherit>emulation</font>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

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Startup mode setup commands</font>

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] \\ |

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Time commands</font>

|  \\ 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

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>Transponder management</font>

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.

 \\ <font 10pt/-apple-system;;rgb(36, 41, 46) font-family: -apple-system; font-size: 10pt;;;inherit>How to register RC4 transponder</font>

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 <font inherit/inherit;;inherit;;inherit>tx number</font>, 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 <font inherit/inherit;;inherit;;inherit>tx number</font>, for example DELETE 3462137, will remove a transponder registration from the decoder memory.

The INFO <font inherit/inherit;;inherit;;inherit>tx number</font>, 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.
