Arduino Saboda: komai game da wannan hukumar ci gaban hukuma

Kila ba za ku gamsu da ɗayan kwamitocin ci gaban hukuma ba. Idan kuwa haka ne, ya kamata ku sani Arduino Saboda, wani daga cikin dandano na hukuma na wannan dandamali mai ban sha'awa. Da shi zaku iya ƙirƙirar ayyuka da yawa, kamar waɗanda suka gabata, amma a wannan yanayin akwai mahimmancin halaye daban-daban, kuma ba kawai ƙwaƙwalwa ba ne, wadatar GPIOs ko girman ...

Ina magana ne game da microcontroller wanda ya hade wannan hukumar, tunda babban guntu ba haka bane dangane da ARM. Abune mai wahala a cikin Arduino, tunda sauran sun dogara ne akan gine-ginen AVR 8-bit, yayin da wannan ɗayan hukumar ke amfani da 32-bit ISA ARM. Tabbas, wannan guntu har yanzu daga samfurin Atmel ne, kamar yadda aka saba.

Menene Arduino Saboda?

Wannan Arduino Saboda kwamiti yana da kamanceceniya da sauran allon ci gaban Arduino, kuma amfaninsa daidai yake. Wannan shine, don ƙirƙirar ɗimbin ayyukan lantarki da tsara zane-zane daban-daban don sarrafa su. Amma, kamar sauran sifofin Arduino, yana da sanannun bambance-bambance ...

Halaye na fasaha, makirci da pinout

Sabbin Arduino ya dogara ne akan MCU ko kwakwalwan microcontroller kamar su Saukewa: SAM3X8E. Kwamitin farko na Arduino wanda zai kasance bisa ARM, musamman maɓallin sarrafa 3-bit Cortex-M32. Aikace-aikace sama da 8-bit MCUs wanda sauran allon kama suke dashi.

Wannan guntu na Atmel (wanda a yanzu aka samu ta Kamfanin Microchip) ta fara jerin nata ne a shekarar 2009 don yin gogayya da nata AVRs. Wasu RISC waɗanda suke da ban sha'awa da ƙarfi fiye da waɗanda suka gabata.

Bayan wannan, kusan, ma kuna da karin filkamar yadda ya hada da nau'ikan I / O dijital 54, wanda 12 daga ciki sakamakonsu ne PWM. Hakanan ya hada da abubuwan analog guda 12, 4 UARTs (mashigin gidan kayan masarufi), da sauransu. Hakanan, ba kamar sauran allon Arduino ba, Arduino Due yana gudana a 3.3v maimakon 5v na sauran allon.

Wannan kwamitin Arduino Due yana da duk abin da kuke buƙata don fara ƙirƙirar ayyukan ku, kawai haɗa shi zuwa PC ta amfani da microUSB na USB kuma fara sauke zane-zanenka don fara aiki. Kuma af, wannan USB ɗin bazaiyi aiki azaman ƙarfin waje kamar yadda yake a wasu lokuta ba, amma kuna iya amfani da adaftan AC / DC wanda ya dace da fulogin da wannan kwamitin yake haɗawa (matsakaicin tsakiya + 2.1mm).

A gefe guda, ya kamata ku ma san nasu halaye na fasaha, waɗanda aka taƙaita su a cikin:
