Kita dapat mengontrol ClockTamer melalui USB atau SPI. Jika tersambung ke USB, ClockTamer akan mengemulasi serial port, oleh karenanya kita dapat mengontrolnya menggunakan terminal emulator, baik dari script atau program. Sambungan SPI digunakan jika ClockTamer tersambung ke USRP dan sangat berguna jika kita tidak ingin menggunakan dua kabel USB dari USRP ke komputer yang kita gunakan.
Komunikasi dengan ClockTamer
Keberadaan ClockTamer dapat dilihat melalui perintah
ls /dev/tty*
harusnya ada device ClockTamer
/dev/ttyACM0
ClockTamer menggunakan protokol berbasis text dan pada dasarnya sama baik itu untuk interface ClockTamer USB maupun SPI. Protokol versi USB dan SPI berbeda hanya pada cara jawaban dari ClockTamer di kirim. Jika menggunakan sambungan SPI kita perlu poll untuk memperoleh jawaban, seperti di jelaskan di halaman interface SPI, di Linux sebelum kita melakukan pertukaran data sebaiknya kita matikan echo dari ClockTamer serial device. Melalui command line kita dapat mematikan melalui perintah berikut,
stty -F /dev/ttyACM0 -echo
Dimana /dev/ttyACM0 adalah ClockTamer serial device file.
Install screen
sudo apt-get install screen
Komunikasi menggunakan perintah
sudo screen /dev/ttyACM0 115200,cs8,-ixon,-ixoff
Tekan
ENTER
Akan keluar
CMD ERROR
berarti kita berhasil berkomunikasi dengan ClockTamer
Fitur Protokol ClockTamer
Protokol ClockTamer mempunya fitur:
- Bekerja dengan pola master / slave. Dengan ClockTamer sebagai slave. Hal ini berarti ClockTamer hanya akan menjawab perintah yang dikirim oleh host dan tidak dalam memberikan perintah atau bertanya ke host.
- Semua Perintah dan Jawaban dalam string ASCII, ditutup dengan CR/LF. Hal ini menyebabkan sangat mudah untuk memberikan perintah ke ClockTamer dengan mode interaktif melalui program terminal emulator.
- Setiap perintah dari host akan di ikuti oleh jawaban dari ClockTamer, artinya protokol yang digunakan sifatnya sinkron (synchronous). Kira-kira sama dengan SD/MMC - jika kita mengirim command maka kita harus menunggu sampai kita menerima jawaban. Jika tidak ada jawaban untuk jangka waktu yang lama, maka kemungkinan besar ada sesuatu yang salah dan itu adalah bug. Sangat di rekomendasikan untuk me-reset ClockTamer dan mencoba lagi. Jangan lupa untuk menlaporkan bug tersebut.
Untuk mereka yang Tidak Sabar
Jika kita ingin langsung menggunakan ClockTamer tanpa perlu mengetahui berbagai detail yang ada, kita minimal membutuhkan dua (2) perintah berikut,
SET,,OSC,<osc_freq> SET,,OUT,<out_freq>
dimana kita harus mengganti,
- osc_freq dengan frekuensi (Hz) dari (VC)TCXO yang terpasang di ClockTamer, contoh 20000000. Perlu di catat bahwa kita dapat mengkalibrasi ClockTamer dengan mengubah sedikit osc_freq. Baca ClockTamer calibration untuk instruksi lebih detail.
- out_freq dengan frekuensi output yang diinginkan (Hz).
Contoh
SET,,OSC,20000000 SET,,OUT,52000000
Jika kita sudah puas dengan settingan yang ada, kita dapat menyimpan parameter tersebut ke EEPROM dan digunakan sesudah reboot:
STE
Command dan struktur jawaban
Setiap perintah menggunakan format
CMD[,TYP[,DET[,value]]]<CR><LF>
Dimana
CMD - kelas command tiga huruf, harus berupa string yang tidak kosong. TYP - command tipe target tiga huruf. Dapat berupa string yang kosong, walaupun DET dan value ada isinya (misalnya, SET,,OSC,10000200). DET - command detail target tiga huruf. Dapat berupa string kosong, walaupun value ada. (e.g. PIN,LED,,0). value - desimal atau hexadesimal value. Value desimal mulai digit (contoh, 54781), Value hexadecimal mulai dengan huruf 'x' (contoh, x01af3d).
Tergantung pada kelas command, perintah yang belakangan dapat di acuhkan sama sekali, seperti:
LDE - only CMD is present INF,,OSC - CMD, TYP and DET are present with TYP as empty string INF,,OUT
Format jawaban adalah sebagai berikut:
- Jika command tidak memberikan value, maka jawaban adalah
OK<CR><LF>
- Jika command memberikan value, jawaban akan mengunakan struktur yang sama dengan command yaitu
CMD[,TYP[,DET[,value]]]<CR><LF>
where CMD, TYP and DET repeats the respective fields in the command.
- Jika command tidak dapat di parsing maka akan mengeluarkan error sebagai berikut:
SYNTAX ERROR<CR><LF>
Command classes
Register ("REG")
Write data ke register di chip yang sesuai MicroWire bus. Menggunakan cpmmand ini kita dapat mengontrol setiap aspek dari pembangkitan clock dalam mode manual. Tipe target dan detail kombinasi yang di ijinkan adalah:
TYP DET value Description LMK <empty> 32bit value Write to LMK (clock distributor) chip registers LMX <empty> 24bit value Write to LMX (PLL+VCO) chip registers (if LMX is present) DAC <empty> 16-24bit value Write to DAC (Digital-to-Analog Converter) chip registers (if DAC is present)
Pin ("PIN")
Kontrol pin dari chip. Tipe target dan kombinasi detail yang di ijinkan adalah:
TYP DET value Description LMK ENB 0/1 ENABLE pin of LMK (clock distributor) chip. LMK GOE 0/1 GOE pin of LMK (clock distributor) chip. LMX SYN 0/1 SYN pin of LMX (PLL+VCO) chip. LED <empty> 0/1 Turn LED on/off.
Set ("SET")
Easy to use setting of output frequency, setting oscillator calibration value, changing algorithms internal variables. The most useful target type and detail combinations:
TYP DET value Description <empty> <empty> <empty> Write all control registers from MCU RAM to LMX and LMK chips. <empty> OSC integer Set oscillator frequency. Used when oscillator is changed, when external frequency source changed its frequency or to calibrate oscillator. Control registers of LMK and LMX are recalculated and written to the chips with this command. <empty> OUT integer Set ClockTamer output frequency. Control registers of LMK and LMX are recalculated and written to the chips with this command. <empty> AUT 0/1 If set to 1 ClockTamer will load all variables from EEPROM and start generator on boot. LMK <empty> <empty> Write all control registers of LMK to the chip. LMK PRT integer Change value of LMK output mask. See description of LMK_OutMask EEPROM register for details. Control registers of LMK are written to the chip with this command. GPS SYN <empty> One-time synchronization to GPS. GPS AUT 0/1 If set to 1 ClockTamer will keep clock synchronized to GPS.
Save ("SAV")
BELUM DI IMPLEMENTASIKAN
Defaults ("DEF")
BELUM DI IMPLEMENTASIKAN
Info ("INF")
Get value of the selected variable. Every variable (specified in DET), usable with SET has its INF counterpart. There is no NFO command with empty DET, though.
There are also a set of variables for debugging purposes only. You don't need to touch them if you don't change the firmware. Also their meaning may change from one firmware version to another without API version change. Currently available target type and detail combinations:
TYP DET value Description GPS DIV <empty> Debug output. Value of divider of LMK output, routed to MCU input. GPS KBT <empty> Debug output. GPS R00 <empty> Debug output. GPS R01 <empty> Debug output. In ClockTamer-1.2 it gives you a number of received 1pps ticks. If this value is increasing, then GPS lock is acquired. GPS R02 <empty> Debug output. GPS R03 <empty> Debug output. In ClockTamer-1.2 it gives you calculated output frequency, multiplied by 32, i.e. Fout = R02/32. GPS MAX <empty> Debug output. GPS MIN <empty> Debug output.
Version ("VER")
Get firmware and protocol versions.
Example:
ClockTamer SW=1.23 API=1
Hardware information ("HWI")
Get detailed information about installed hardware options. This information is stored in EEPROM and may be altered only if ClockTamer is flashed over SPI. Flashing over USB can not change EEPROM data.
Values shown in HWI string incude:
LMX= Type of LMX2531 VCO+PLL. Can be "2080" for LMX2531LQ2080E or "1515" for LMX2531LQ1515E. Most ClockTamers have LMX2531LQ2080E. LMK= Type of LMK01000 Clock Buffer, Divider, and Distributor. Can be "1000" for LMK01000, "1010" for LMK01010 or "1020" for LMK01020, but is usually LMK01010. OSC=
FOSC= Frequency of the reference TCXO or VCTCXO in MHz. Possible values are 10, 20 or 26. GPS ClockTamer has GPS module installed if GPS is present in HWI. VCTCXO ClockTamer use VCTCXO with DAC instead of TCXO with VCO+PLL is VCTCXO is present in HWI.
Example of HWI for a ClockTamer with LMX2531LQ2080E, LMK1010, 20MHz TCXO and GPS:
LMX=2080 LMK=1010 OSC=20 GPS
Reset ("RST")
Sends reset command to LMK and LMX and clears variables in MCU RAM, but does not affect EEPROM. To start output generation after RST you can execute "SET,,OSC,<val>", "SET,,OUT,<val>" or "LDE"+"SET".
Load EEPROM ("LDE")
Loads previously stored values from EEPROM to RAM. This command does not push them to LMK and LMX chips, so you should execute SET command manually.
TYP, DET and value should be empty.
Store EEPROM ("STE")
Stores all values to EEPROM. This values will be used by default after ClockTamer reboot. They can also be loaded to RAM at any time with LDE command.
TYP, DET and value should be empty.
EEPROM variables list
Variable Description Fosc Oscillator frequency Fout Output frequency VCO_MIN Parameter for calculation of VCO registers for LMX. Shouldn't be changed unless you change LMX on your unit. VCO_MAX Parameter for calculation of VCO registers for LMX. Shouldn't be changed unless you change LMX on your unit. VCO_Kbit Parameter for calculation of VCO registers for LMX. Shouldn't be changed unless you change LMX on your unit. LMK_OutMask Enable/disable output generation on specific LMK outputs. Set bit in the mask to 1 to enable corresponding output and to 0 to disable it. E.g. x60 value will enable 5 and 6 outputs and disable all others. See outputs numbering below. AutoFreq Autostart generating output on boot. DacValue DAC value if VCTCXO is used. AutoGPSSync Continuously synchronize clock to GPS.
Outputs numbering
ClockTamer-1.0
If you look at ClockTamer so that "ClockTamer v1.0" label reads normally, then outputs are numbered in the following way:
2 0 .---. |LMK| 7 .---. 6 4 5 6*
where 0,2,4,5,6 - places for U.FL connectors, 6* - a place for SMA connector. Outputs number 1 and 3 are not present on PCB. In default configuration outputs number 0 and 2 are LVDS, while 4,5,6 are LVPECL/CMOS.
ClockTamer-1.1 and ClockTamer-1.2
Outputs numbering is as shown on the picture:
Outputs 1 and 6 and CMOS, while outputs 0, 3, 4, 5 and 7 are LVDS or half-LVDS. Refer to Features and technical specification page for more information about half-LVDS outputs.
