Idan ba za ka gwammace ka yi amfani da serial terminal don gyara saitunan akan OpenLog ɗinka ba, za ka iya sabunta saitunan ta hanyar gyara CONFIG.TXT. file.
Lura: Wannan fasalin yana aiki ne kawai akan firmware verison 1.6 ko sabo. Idan kun sayi OpenLog bayan 2012, za ku yi amfani da sigar firmware 1.6+
Don yin wannan, kuna buƙatar mai karanta katin microSD da editan rubutu. Bude config.txt file (capitalization na file sunan ba kome), kuma saita tafi! Idan baku taɓa kunna OpenLog ɗinku tare da katin SD ba a baya, zaku iya ƙirƙirar da hannu file. Idan kun kunna OpenLog tare da katin microSD da aka saka a baya, yakamata ku ga wani abu kamar haka lokacin da kuka karanta katin microSD.
OpenLog yana ƙirƙirar config.txt da LOG0000.txt file a farko iko up.
Tsarin tsoho file yana da layi ɗaya na saituna da layi ɗaya na ma'anar.
Tsari na asali file OpenLog ne ya rubuta.
Lura cewa waɗannan haruffan bayyane ne na yau da kullun (babu waɗanda ba a iya gani ko ƙima ba), kuma kowace ƙima ta rabu da waƙafi.
An bayyana saitunan kamar haka:
- baud : The sadarwa baud rate. 9600bps tsoho ne. Ƙididdiga masu dacewa waɗanda suka dace da Arduino IDE sune 2400, 4800, 9600, 19200, 38400, 57600, da 115200. Kuna iya amfani da wasu ƙimar baud, amma ba za ku iya sadarwa tare da OpenLog ta hanyar Arduino IDE serial.
- gudun hijira: Ƙimar ASCII (a cikin sigar ƙima) na halin tserewa. 26 shine CTRL+z kuma tsoho ne. 36 shine $ kuma halin tserewa ne da aka saba amfani dashi.
- esc# : Adadin haruffan tserewa da ake buƙata. Ta hanyar tsoho, uku ne, don haka dole ne ka buga halin tserewa sau uku don sauke zuwa yanayin umarni. Ƙididdiga masu karɓuwa daga 0 zuwa 254. Saita wannan ƙimar zuwa 0 zai hana bincika halayen tserewa gaba ɗaya.
- yanayin: Yanayin tsarin. OpenLog yana farawa a Sabon Log yanayin (0) ta tsohuwa. Ƙididdiga masu karɓa sune 0 = Sabon Log, 1 = Log na Jeri, 2 = Yanayin Umurni.
- fi'ili: Yanayin magana. Ana kunna saƙonnin kuskure (verbose) ta tsohuwa. Saita wannan zuwa 1 yana kunna saƙon kuskure na verbose (kamar umarnin da ba a sani ba: cire! ). Saita wannan zuwa 0 yana kashe kurakuran magana amma zai amsa da ! idan akwai kuskure. Kashe yanayin magana yana da amfani idan kuna ƙoƙarin magance kurakurai daga tsarin da aka saka.
- echo: Yanayin echo. Yayin da ake cikin yanayin umarni, haruffa ana maimaita su ta tsohuwa. Saita wannan zuwa 0 yana kashe echo. Kashe wannan yana da amfani idan ana sarrafa kurakurai kuma ba kwa son a sake maimaita umarnin da aka aiko a baya zuwa OpenLog.
- watsiRX: Sauke Gaggawa. A al'ada, OpenLog zai sake saitin gaggawa lokacin da RX fil ya ja ƙasa yayin sama. Saita wannan zuwa 1 zai kashe duban fil ɗin RX yayin haɓaka wutar lantarki. Wannan na iya zama taimako ga tsarin da zai riƙe layin RX ƙasa don dalilai daban-daban. Idan An kashe Gyaran Gaggawa, ba za ku iya tilasta naúrar baya zuwa 9600bps ba, da daidaitawa. file zai zama hanya ɗaya tilo don gyara ƙimar baud.
Yadda OpenLog ke Gyara Tsarin Kanfiga File
Akwai yanayi daban-daban guda biyar don OpenLog don gyara config.txt file.
- Saita file samu: Yayin da ake haɓakawa, OpenLog zai nemi config.txt file. Idan da file An samo, OpenLog zai yi amfani da saitunan da aka haɗa kuma ya sake rubuta duk wani saitunan tsarin da aka adana a baya.
- Babu saitin file samu: Idan OpenLog ba zai iya samun config.txt ba file to OpenLog zai ƙirƙiri config.txt kuma ya yi rikodin saitunan tsarin da aka adana a halin yanzu. Wannan yana nufin idan kun saka sabon katin microSD wanda aka tsara, tsarin ku zai kula da saitunan sa na yanzu.
- Saitin lalatacce file samu: OpenLog zai goge gurɓataccen config.txt file, kuma zai sake rubuta duka saitunan EEPROM na ciki da saitunan config.txt file zuwa sananne-kyau jihar 9600,26,3,0,1,1,0 .
- Ƙimar da ba bisa doka ba a cikin saitin file: Idan OpenLog ya gano duk wani saitunan da ke dauke da dabi'u ba bisa ka'ida ba, OpenLog zai sake rubuta gurɓatattun dabi'u a cikin config.txt file tare da saitunan tsarin EEPROM da aka adana a halin yanzu.
- Canje-canje ta hanyar umarni da sauri: Idan an canza saitunan tsarin ta hanyar umarni da sauri (ko dai ta hanyar haɗin yanar gizo ko ta hanyar umarni na microcontroller) waɗannan canje-canje za a rubuta su duka zuwa tsarin EEPROM da kuma zuwa config.txt. file.
- Sake saitin gaggawa: Idan OpenLog yana yin keken keke tare da jumper tsakanin RX da GND, kuma an saita bit of Reverride na gaggawa zuwa 0 (ba da izinin sake saitin gaggawa), OpenLog zai sake rubuta duka saitunan EEPROM na ciki da saitunan config.txt. file zuwa sananne-kyau jihar 9600,26,3,0,1,1,0 .
Shirya matsala
Akwai zaɓuɓɓuka daban-daban da yawa don bincika idan kuna da matsalolin haɗawa akan serial Monitor, kuna da matsala tare da abubuwan da aka jefar a cikin rajistan ayyukan, ko yaƙi da OpenLog bricked.

Biyu Duba Tsarin Rubutun Rubutu
Idan kana amfani da tsohowar OpenLog.ino exampHar ila yau, OpenLog zai goyi bayan ƙananan kundin adireshi biyu kawai. Kuna buƙatar canza FOLDER_TRACK_DEPTH daga 2 zuwa adadin ƙananan bayanan da kuke buƙatar tallafawa. Da zarar kun gama wannan, sake tattara lambar sama, sannan ku loda firmware da aka gyara.
Tabbatar da Lambar Files a cikin Tushen Directory
OpenLog zai goyi bayan log ɗin 65,534 kawai files a cikin tushen directory. Muna ba da shawarar sake fasalin katin microSD don inganta saurin shiga.
Tabbatar da Girman Firmware ɗin da aka gyara
Idan kuna rubuta zanen al'ada don OpenLog, tabbatar da cewa zanenku bai fi 32,256 girma ba. Idan haka ne, za ta yanke cikin babba 500 bytes na Flash memory, wanda Optiboot serial bootloader ke amfani da shi.
Duba sau biyu File Sunaye
Duka file sunayen su zama alpha-lambobi. MyLOG1.txt yayi kyau, amma Hi !e _.txt bazai yi aiki ba.
Yi amfani da 9600 Baud
OpenLog yana aiki daga ATmega328 kuma yana da iyakataccen adadin RAM (bytes 2048). Lokacin da kuka aika serial characters zuwa OpenLog, waɗannan haruffan suna ɓoyewa. Ƙayyadaddun Sauƙaƙe Ƙungiya na SD yana ba da damar katin SD ya ɗauki har zuwa 250ms (sashe 4.6.2.2 Rubuta) don yin rikodin toshe bayanai zuwa ƙwaƙwalwar walƙiya.
A 9600bps, wato 960 bytes (10 bits per byte) a sakan daya. Wato 1.04ms kowace byte. OpenLog a halin yanzu yana amfani da 512 byte karɓar buffer don haka zai iya adana kusan 50ms na haruffa. Wannan yana bawa OpenLog damar samun nasarar karɓar duk haruffa masu zuwa a 9600bps. Yayin da kuke ƙara ƙimar baud, buffer ɗin zai šauki na ɗan lokaci.
Buffer Buffer Lokacin wucewa
| Baud Rate | Lokaci kowane byte | Lokaci Har sai Buffer ya cika |
| 9600 bps | 1.04ms | 532ms |
| 57600 bps | 0.174ms | 88ms |

Yawancin katunan SD suna da saurin rikodin lokacin fiye da 250ms. Wannan zai iya shafar 'class' na katin da adadin bayanan da aka riga aka adana akan katin. Magani shine a yi amfani da ƙananan baud kudi ko ƙara yawan lokaci tsakanin haruffan da aka aika a mafi girma na baud.
Tsara Katin MicroSD ɗin ku
Ka tuna amfani da kati mai ƴan kaɗan ko a'a files da shi. Katin microSD tare da darajar 3.1GB na ZIP files ko MP3s suna da lokacin amsawa a hankali fiye da katin wofi.
Idan baku tsara katin microSD ɗinku akan Windows OS ba, sake tsara katin microSD kuma ƙirƙirar DOS filetsarin akan katin SD.
Canza katunan MicroSD
Akwai nau'ikan masu kera kati daban-daban, katunan da aka yi wa lakabi, girman kati, da azuzuwan kati, kuma maiyuwa ba duka suke aiki da kyau ba. Yawanci muna amfani da katin microSD na 8GB 4, wanda ke aiki da kyau a 9600bps. Idan kuna buƙatar ƙimar baud mafi girma, ko sararin ajiya mafi girma, kuna iya gwada katunan aji 6 ko sama da haka.
Ƙara Jinkirta Tsakanin Rubutun Hali
Ta ƙara ɗan jinkiri tsakanin Serial.print() kalamai, za ka iya ba OpenLog damar yin rikodin halin yanzu

Ƙara Arduino Serial Monitor Compatibility
Idan kuna ƙoƙarin amfani da OpenLog tare da ginannen ɗakin karatu na serial ko ɗakin karatu na SoftwareSerial, kuna iya lura da batutuwa tare da yanayin umarni. Serial.println() yana aika duka sabon layi DA dawowar kaya. Akwai madadin umarni guda biyu don shawo kan wannan.
Na farko shine a yi amfani da umurnin \ r (ASCII karusar dawowa):
