USB-shirye-shiryen kwamfuta (AVR): description, nadi

A rediyo masu gyara da suka so su shiga a cikin shiri na na'urorin lantarki, daga lokaci zuwa lokaci shi wajibi ne don amfani da su a kayayyaki microcontrollers. A amfani da wadannan semiconductor na'urorin Shi yayi girma yiwuwa ga lantarki. Microcontrollers ake samar da kawai 'yan kamfanoni, shugabannin da suke MicrochipTechnology, ATMEL, ARMLimited. A babban alama irin wannan na'urorin ne da bukatar su shirin firmware. Domin wannan kuma bukatar shirye-shirye. Don kwanan wata, akwai wata babbar selection na daban-daban na shirye-shirye, duk da haka, farashin irin kayayyakin ne sosai high, da kuma ba kowane rediyo mai son iya sayen irin wannan na'urar.

A wannan labarin, za mu duba a USB-shirye-shiryen (AVR) a kan tushen da iko da microcontroller Atmega 8. Wannan samfurin ne mai sauki isa ga naman alade rediyo ya iya tattara shi da kanka da kuma bã su ciyar da karin kudi a dauke kayayyakin. Mun zaba da kebul-shirye-shiryen (AVR) yana kadan piping microcontroller cewa ba ka damar gina wani sosai kankanin na'urar. Irin wannan samfurin ba dauka da yawa sarari, shi yana da girma da wani al'ada flash. USB-shirye-shiryen kwamfuta (AVR) a cikin makirci qunshi wani microcontroller Atmega 8, da irin gidaje - TQFP 32 (ba za a rikita batun tare da irin tsoma casing, domin suna da daban-daban pinouts). A kewaye da irin wannan na'urar da aka nuna a cikin photo.

Mu ci gaba da bayanin irin kayan kewaye. Jumper J1 da ake amfani a cikin akwati inda akwai bukatar EEPROM microcontroller ciwon Agogon mita kasa 1.5 MHz. Idan so, wannan jumper sauƙi shafe ta daga kewaye, domin wannan 25-th mai kula fitarwa samun to "kasa". A wannan yanayin AVR-USB-shirye-shiryen za su ko da yaushe aiki a rage mita. Ya kamata a lura da cewa shirye-shirye a kan low mita daukan mafi lokaci, amma ga yanke shawara, ba shakka, da ku. Zener diodes D1, D2 ana amfani da matakin daidai da tsakanin bas da kebul-shirye-shiryen. Blue LED nuna na'urar shiri domin shirye-shirye da microcontroller, da ja jagoranci Lights sama a lokacin shirye-shirye. A kewaye da IDC-06 connector ga abin da lambobi aka samu, wanda yayi dace da pinout irin ATMEL ISP 6-pin haši. A ce connector fil-ikon microcontroller, shi aka ɗauke ta daga PC USB-tashoshin jiragen ruwa, saboda haka, kula dole ne a dauki hana short haihuwarka. C da shirye-shirye da kuma iko da kula via guda connector, shi wajibi ne don haɗa Sake saitin lambobin sadarwa a kula da connector (aka nuna a Students ja cike da gidajen gona). Jumper rage shirye-shirye gudun da microcontroller dangane soket located a kan na'urar karshen. Ga abin da yake a USB-shirye-shiryen (AVR), kamar yadda za ka iya gani, duk da na farko.

Bayan taron, da na'urar dole ne a sarrafawa da wani microcontroller zuwa filashi, ga abin da zan bayar da shawarar a yi amfani da shirin PonyProg. Lokacin da shirye-shirye, za mu fara a crystal aiki a kan na waje lokaci tushen ne 12 MHz.

Aka bayyana a cikin wannan labarin, USB-shirye-shiryen ga AVR microcontrollers aiki tare da iri daban-daban AVR, kyale su su dinka, duba da rubuta abinda ke ciki na na'urarka, goge guntu, canja sanyi.
