MICROCONTROLLER PROGRAMMER FOR THE HOUSEHOLD APPLIANCES

Diplomsko delo opisuje razvoj in izdelavo programatorja mikrokrmilnikov ST7, ki so zelo razširjeni v aplikacijah gospodinjskih aparatov. Za osnovo smo vzeli platformo že izdelanega programatorja za ST10, ki smo mu dodali tudi funkcionalnosti za programiranje ST7. Opisali smo značilnosti mikrokrmilnikov ST7, popravke in dodatke na vezju programatorja, protokol programiranja v vezju, postopke brisanja, programiranja in branja pomnilnika mikrokrmilnika. Potrebna je bila tudi sprememba načina pisanja podatkov v vgrajen EEPROM. Dodan je bil večji pomnilniški čip za shranjevanje več programov. Prav tako smo izboljšali uporabniški vmesnik in pripravili kratka navodila za uporabo.This work describes development and construction of a programmer for ST7 microcontrollers, very common controllers in appliacations for household appliances . We used an available programmer for ST10 and upgraded it with functionalities for programming ST7. We describe features of ST7 microcontrollers, corrections and additions to the programmer circuit board, protocol for in-circuit programming, procedures for deleting, programming and reading of microcontroller\u27s memory. It was necessary to change the way of writing data to the built-in EEPROM. We added a larger memory chip for storing more software. We also improved the user interface and prepared short user manuals
