USB-Programmer (AVR): tsananguro, izita

In redhiyo wevanamakanika vanoda kuita mukuvakwa zvemagetsi, nguva nenguva zvakafanira kuzoshandisa mazano avo microcontrollers. Kushandiswa izvi semiconductor mano Rinopa guru tarisiro nokuda Electronics. Microcontrollers anobudiswa nemakambani chete vashoma, vatungamiri vari MicrochipTechnology, ATMEL, ARMLimited. The chikuru chinoratidza vakadaro mano ndiyo kudiwa chirongwa chavo firmware. Nokuti ichi uye zvinodiwa programmers. Zvisinei, kuti musi, pane vakasarudzwa rakasiyana-siyana programmers makuru, mutengo zvigadzirwa zvakadaro zvakakwirira kwazvo, uye kwete ose redhiyo mudzidzi anogona kutenga zano rakadaro.

Munyaya ino tichakurukura USB-programmer (AVR) pahwaro kudzorwa microcontroller Atmega 8. chigadzirwa Izvi nyore zvokuti hamu redhiyo akakwanisa kuunganidza iwe uye musaparadze mari yakawanda pamusoro vakapiswa zvigadzirwa. Isu wasarudza USB-programmer (AVR) ane usingashandi muridzo unoridzirwa microcontroller unokubvumira kuvaka mudziyo duku chaizvo. chigadzirwa akadaro usingatori nzvimbo zvikuru, rine kukura munhu kwakajairika nokupenya. USB-Programmer (AVR) pazano rake unotora munhu microcontroller Atmega 8, mhando redzimba - TQFP 32 (kwete kuti kuvhiringidzwa mhando Dip casing, nekuti vane pinouts yakasiyana). Kutenderera mudziyo yakadaro unoratidzwa mufananidzo.

We mberi kuti rondedzero chiridzwa redunhu. Jumper J1 rinoshandiswa nyaya kunodiwa vaparidzi EEPROM microcontroller ane wachi maitikiro pazasi 1.5 MHz. Kana kutsvakwa, jumper ichi nyore zvachose redunhu, nokuti ichi 25-fung controller goho zvikanzwika "pasi". Muchiitiko ichi AVR-USB-programmer nguva dzose kushanda panguva shoma maitikiro. Zvinofanira kucherechedzwa kuti zvirongwa pamusoro yakaderera kakawanda anotora nguva yakawanda, asi kusarudza Chokwadi, imi. Zener diodes D1, D2 anechekuita sandara enzanirana pakati bhazi uye USB-programmer. Blue akatungamirira inoratidza mudziyo akagadzirira mapurogiramu ari microcontroller, tsvuku akatungamirira ichivhenekera kukwira panguva mapurogiramu. The Dunhu rine IDC-06 connector uko neshamwari hwokurara, izvo rinoenderana pinout mhando ATMEL ISP 6-Pin connector. On akati connector Pin-simba microcontroller, rakundwa kubva PC USB-zvengarava, naizvozvo, zvinoda kungwarira kutorwa kudzivirira nematunhu pfupi. C ari zvirongwa uye kudzorwa controller nomukombiyuta chete connector, zvinokosha kubatanidza Reset vokukurukura pamusoro controller uye connector (kuratidzwa Scheme tsvuku Dziine). Jumper kuderedza zvirongwa nokukurumidza uye microcontroller kubatana nezvigadziko iri mudziyo magumo. Hezvino chii ari USB-programmer (AVR), sezvaungaona, zvose zvokutanga.

Mushure ungano, mudziyo anofanira zvinodzorwa nerimwe microcontroller kuti upenye, nokuti ini yemutemberi kushandisa chirongwa PonyProg. Kana zvirongwa, tatanga panguva sekristaro kushanda pamusoro kwokunze nguva panobva ndiyo 12 MHz.

Zvinotsanangurwa munyaya ino, USB-programmer nokuda AVR microcontrollers anoshanda mhando dzose AVR, achivabvumira kusona, tarisa zvakanyorwa zviri mudziyo wako, dzima Chip, kushandura configuration.
