Menene Teeny?
Teensy alama ce ta hukumar haɓaka microcontroller wanda PJRC ta ƙirƙira kuma tare da zane wanda mai haɗin gwiwar Paul Stoffregen ya shiga. PJRC mai zane ne kuma mai kera na'urori daban-daban don masu yin DIY, haɓaka kerawa, da sauransu. Don yin wannan, sun ƙirƙiri wannan ƙarami, ƙaramin allo tare da yuwuwar Arduino, kuma tare da iko mai ban sha'awa da sassauci, kuma suna amfani da microcontrollers na tushen ARM maimakon AVR da wasu allunan ci gaba iri ɗaya ke amfani da su.
Teensy ba kawai faranti ba ne, amma akwai daban-daban model ko iri., wanda wasu fa'idodi da girman su ya bambanta. Duk waɗannan ƙirar kayan masarufi an ƙirƙira su ne tare da ra'ayin haɓaka damar I/O, da kuma samun goyan bayan ɗimbin ɗakunan karatu na software don samar da fasali da yawa kuma a shirye suke don aiki tare da Arduino IDE.
Halayen fasaha na Teensy
Kuna iya ganin cikakkun bayanai na ƙirar ku a cikin takaddun bayanan da masana'anta suka bayar. Har ila yau, ku tuna cewa za a iya samun bambance-bambance a tsakanin nau'ikan iri. Koyaya, don samun ɗan ɗan ƙarin ra'ayi na Teensy wanda ya zama gama gari ga duka, ga wasu daga cikinsu. halayen fasaha:
- Karfinsu tare da arduinosoftware da dakunan karatu. Hakanan, yana da ƙari don Arduino da ake kira teensyduino
- Tashar USB
- app Teensy Loader don sauƙin amfani
- Software na haɓaka kyauta
- Tallafin-dandamali, akwai don Linux, MacOS da tsarin aiki na Windows
