USB-Programmer (AVR): hōʻikeʻano, inoa

I Radio technicians ka poe i makemake e komo i loko o ka hana o ka mīkini uila no, mai ka manawa i ka manawa ia mea pono e hana i loko o kā lākou mau manao microcontrollers. Ke hoʻohana i kēia mau mea uholo uila manao ona Ua kaumaha weliweli no ka manaʻolana 'ia no nāʻano uilaʻoe. Microcontrollers i hua mai ma ka wale i kekahi mau poʻe, alakaʻi o ka i mea MicrochipTechnology, ATMEL, ARMLimited. Ke kumu nui hiʻona o ua mau mea nei i ka pono no lākou polokalamu firmware. No keia a pono programmers. I ka lā, aia no he nui koho o keʻano o nā programmers, nae, i ke kumu kūʻai o ia huahana Ua loa kiʻekiʻe, aʻaʻole na Radio loira hiki ke hoolawaia ma ke kuai ia i kekahi mea.

Ma kēia 'atikala e nānā mākou i USB-programmer (AVR) ma luna o ke kumu o ka mana o ka microcontroller Atmega 8. kēia huahana mea puni lawa i ka Hama Radio ua hiki ke ohi ia oe iho, a mai hoomaunauna i hou dala ma kuni nā huahana. Ua koho mākou i ka USB-programmer (AVR) mai ka palena haʻahaʻa hookiokio aku microcontroller e leie aku oe, e kūkulu i ka loa wahi mea hoʻoluku. Oia kekahi huahana, aole ia i lawe mai i ka wa pokole, ka mea, i na Ana o kaʻike mau waihonaʻike. USB-Programmer (AVR) i loko o kona noaia maupaʻa i ka microcontroller Atmega 8, ke 'ano o ka hale - TQFP 32 (ʻaʻole ia e hookahuli ai i ke' ano o ka hou iho i pōkā pū, no ka mea, i okoa pinouts). Ke kaapuni ana o ia ka mea ua hoike mai i loko o ka Hawaii photo.

E hoomau aku a hiki i ka hōʻike o ka mea kani huakai kaapuni. Jumper J1 ua hoʻohana 'ia i loko o ka hihia ma laila mea he pono EEPROM microcontroller me ka uaki alapine (frequency) ma lalo 1.5 MHz. Inā makemake, keia jumper eaaei eliminated mai ka huakai kaapuni, no keia 25-la eiioeieeae auaiaea loaʻa i ka "lepo". Ma keia hihia AVR-USB-programmer, e mau hana ma ka hoemiia alapine (frequency). It E e hoʻomaopopo i ka iaaiey ma ka haʻahaʻa alapine (frequency) i oi manawa, akā, e hooholo, o ka papa, oe. Zener diodes D1, D2 e noi i kaʻilikai'ālike ma waena o ke kaʻa'ōhua, a me ka USB-programmer. Blue LED Hōʻike ka mea mākaukau no ka iaaiey i ka microcontroller, ka ula LED anapu mai i iaaiey. Ke kaapuni i IDC-06 hūlili ia i ka hui 'ana i loko, a hoʻopili like i ka pinoutʻano ATMEL ISP 6-Pins hūlili. Ma la hūlili kui-mana microcontroller, ua lawe ia mai ka PC USB-awa, nolaila, pono e lawe malama, e ole pokole wahi i puhi ai. C ka iaaiey, a me ka hooponopono ana o ka eiioeieeae Via ka ia hūlili, ia mea pono e hoʻohui i ka Ho'ā hou hui 'ana ma luna o ka eiioeieeae, a me ka hūlili (i hoikeia ma noaia ula dotted). Jumper emi i ka iaaiey māmā a me ka microcontroller pilina kumu aia ma luna o ka mea hope. Eia ka ka mea he USB-programmer (AVR), e like me oe e ike, a pau ke kula haʻahaʻa.

Ma hope oʻaha kanaka, pono e hoʻomalu aku i ka mea ma ka microcontroller e Flash, no ka mea aʻu e paipai aku, e hoʻohana i ka polokalamu PonyProg. I ka iaaiey, ua hoʻomaka i ke aniani functioning ma luna o ka mea mawaho manawa kumu o 12 MHz.

I ho'ākāka 'ia i loko o kēia' atikala, USB-programmer no AVR microcontrollers hana me nā ano o AVR, hiki ia lakou i ka humuhumu, e makaala i ka kākau Contents o kou manaʻo, holoiia inoaia, e hoʻololi i ka hoʻonohonohoʻia.
