Sizonikezela lesi sihloko ku- ibhodi lokuthuthukiswa kwentsha. Ibhodi eliguquguqukayo kakhulu, elihambisana ne-Arduino, futhi likasayizi oncishisiwe ukuze likwazi ukulinikezela kumaphrojekthi lapho ubukhulu bubalulekile khona. Lapha ungabona ukuthi kuyini, izinhlobo nezinguqulo ezikhona, izici zobuchwepheshe, nokuthi yini engenziwa ngaleli bhodi nge-MCU noma i-microcontroller.
Iyini i-Teeny?
I-Teensy iwuphawu lwebhodi lokuthuthukisa i-microcontroller elakhiwe yi-PJRC kanye nomklamo lapho omunye wabanikazi u-Paul Stoffregen ebambe iqhaza. I-PJRC ingumklami nomkhiqizi wamadivayisi ahlukene abakhi, i-DIY, ukuthuthukiswa kokusungula, njll. Ukuze benze lokhu, badale leli bhodi elincane, eliguquguqukayo kakhulu elinamandla e-Arduino, futhi elinamandla amangalisayo nokuguquguquka, futhi basebenzisa ama-microcontrollers asekelwe ku-ARM esikhundleni sama-AVR asetshenziswa amanye amabhodi okuthuthukiswa afanayo.
I-Teensy ayiyona nje ipuleti, kodwa ikhona amamodeli ahlukene noma izinguqulo., lapho ezinye izinzuzo nobukhulu bazo zihluka. Yonke le miklamo yezingxenyekazi zekhompuyutha idalwe ngombono wokukhulisa amakhono e-I/O, kanye nokusekelwa inqwaba yamatapo olwazi esoftware ukuze inikeze izici eziningi futhi ilungele ukusebenza nge-Arduino IDE.
Izici zobuchwepheshe ze-Teensy
Ungabona imininingwane yemodeli yakho kumininingwane yedatha enikezwe umenzi webhodi. Futhi, khumbula ukuthi kungase kube khona umehluko we-pinout phakathi kwezinguqulo. Kodwa-ke, ukuze ube nombono ojwayelekile kakhudlwana we-Teensy ojwayelekile kubo bonke, nazi ezinye izici zayo zobuchwepheshe:
- Ukuhambisana ne- i-arduinosoftware kanye nemitapo yolwazi. Futhi, inesengezo se-Arduino esibizwa i-teensyduino
- Imbobo ye-USB
- App I-Teensy Loader ukuze kube lula ukusetshenziswa
- Isofthiwe yokuthuthukisa yamahhala
- Ukusekelwa kwe-Cross-platform, kuyatholakala ku-Linux, MacOS kanye nezinhlelo zokusebenza zeWindows
- Usayizi omncane, ofanele amaphrojekthi amaningi
- Itholakala ngezikhonkwane ze-breadboard noma ngaphandle kwazo
- Uhlelo olulodwa lwenkinobho yokucindezela
- Ingabe unaye umdidiyeli? I-WinAVR
- Ukulungisa iphutha le-USB
Olunye ulwazi lobuchwepheshe nokulanda - Iwebhusayithi esemthethweni ye-PJRC
Izinhlobo nokuthi ungathenga kuphi
Mayelana nezinhlobo zamapuleti e-Teensy kanye nawo Ukucaciswa kobuchwepheshe, sinokuhlukahluka okulandelayo ngokuphathelene nezici ezivamile zesigaba sangaphambilini:

Yini engenziwa nge-Teensy ehlukile kwamanye amapuleti? (Izinhlelo zokusebenza)
Ibhodi lokuthuthukisa i-Teensy lingelinye elaziswa kakhulu abenzi abaningi ngezizathu ezimbalwa. Enye yezinto eziyinhloko ihlobene ne-chip amanye alawa mabhodi afakwe ngayo, ngoba asekelwe 32-bit ARM chips. Lokhu akuhlinzeki ngokusebenza okuphezulu kuphela kune-AVR, futhi kuvumela ukuba ne-MCU yesimanjemanje, ukusebenza ngezakhiwo ezibalulekile futhi ezisabalele namuhla njenge-ARM, njll.
Ngakolunye uhlangothi, naphezu kobukhulu bayo obuncane, zinamandla impela, enekhono elihle le-RAM, i-flash kanye nememori ye-EEPROM, kanye nezikhonkwane ezicebile zokuxhuma ukusebenzisa ama-peripherals we-hardware, ngisho namakhadi e-SD, i-Ethernet, njll. Futhi konke lokhu ngaphandle kokukhipha i-iota yokuhambisana ne-Arduino. Kodwa njengoba ubona, akuyona "enye", kodwa ekhethekile.
Esinye isici esihle se-Teensy ukuthi ingasebenza njenganoma iyiphi enye idivayisi ye-USB yomdabu, okungukuthi, ungahlela ibhodi ukuthi libe yi-peripheral futhi lisebenze njenge-HID, idivayisi ye-MIDI, izinduku zokudlala, amaphedi omdlalo, njll. Futhi konke lokho ngaphandle kwekhodi eyengeziwe, konke kuyingxenye yesitaki sesofthiwe ye-Teensy ngakho-ke akufanele ukhathazeke ngakho. Ngokuqondene ne-Teensyduino, i-addon ye-Arduino IDE, ingesinye isici esihle, futhi kuthatha umzuzwana nje ukuvuka nokusebenza...
