Lenaneo la IC

Lenaneo la software le akaretsang le shebana le ditshebediso tse ditsamaisong tsa tshebetso tsa khomphutha, le sebedisa dipuo tsa maemo a hodimo, mme le sebetsa hodima diprosesa tse akaretsang. Lenaneo la IC le sebelisana ka ho toba le di-chip tsa hardware, le hloka ho nahanelwa ha dibopeho tsa hardware tse kang direjistara le diprothokholo tsa puisano, hangata le sebedisa puo ya kopano kapa dipuo tse ikgethang tsa di-chip, mme le boloka diphetho memoring ya chip e sa fetoheng.

Mefuta e tloaelehileng e kenyelletsa li-microcontroller (MCUs), li-microprocessor (MPUs), li-field-programmable gate arrays (FPGAs), li-flash memory chip, le li-digital signal processors (DSPs).

E fa li-IC mokhoa o itseng oa boitšoaro. Mohlala, chip ea Bluetooth e hlophisitsoe ho beha mekhoa ea ho sebetsa le liparamente tsa puisano bakeng sa khokahano ea sesebelisoa le phetisetso ea data. Ntle le lenaneo, IC ke "sehlahisoa se felileng hanyane" feela sa hardware.

Bakeng sa di-IC tse kgonang ho ntsha tlhahiso, hlokomela hore na matshwao a tsamaisana le ditebello ka kgokelo ya potoloho (mohlala, ho panya ha LED jwalo ka ha ho hlophisitswe). Bakeng sa di-IC tsa memori, bala data le lenaneo kapa o hlahlobe difolaga tsa boemo ba chip.

Ho tšoana: Ka bobeli li sebelisa li-interface tsa puisano ho fetisetsa data ho memori ea chip.

Phapang: Li-MCU li ngola khoutu ho Flash ka li-interface tsa JTAG/SWD; Li-FPGA li kenya data ea tlhophiso litafoleng tsa ho batla (LITs) ho hlophisa bocha mokhoa oa hardware, 'me data hangata e bolokoa ka har'a flash ea kantle le ho kenngoa ka SPI.

E kenyelletsa ho khetha hardware/software ea mananeo, ho hokahanya hardware le IC, ho beha liparamente tsa chip, ho kenya lifaele tsa mananeo (.hex/.bin, jj.), ho kenya tšebetsong mananeo, le ho etsa liteko tsa netefatso le tsa ts'ebetso.

"Burn-in" ke lentsoe le tloaelehileng bakeng sa lenaneo la IC, le bolelang ho ngola khoutu ka ho sa feleng memoring e sa fetoheng ea chip (mohlala, Flash ea MCU). Lentsoe lena le simolohile mesebetsing ea pele ea "ho chesa" ea motlakase o phahameng 'me le ntse le sebelisoa le kajeno.

Memori e bolokang data ha motlakase o timme. Mefuta e tloaelehileng mananeong a IC e kenyelletsa Flash (e boloka khoutu/data) le EEPROM (e boloka tlhahisoleseling ea tlhophiso), ho fapana le memori e feto-fetohang (mohlala, RAM).

Software e kentsweng disebedisweng tsa hardware, e bolokwa memoring e sa fetoheng ya IC, e laola mesebetsi ya motheo le ho fana ka di-interface bakeng sa software ya maemo a hodimo, jwalo ka router firmware e laolang dikgokelo tsa marangrang.

Phapang e teng ho li-interface tsa mananeo (mohlala, JTAG/SWD ea ST khahlanong le ICD ea Microchip), lisebelisoa (mohlala, ST-Link khahlanong le MPLAB X), litlhophiso tsa rejistara, le tšehetso ea puo ea mananeo.

E hloka phepelo e tsitsitseng ea motlakase, mehato e khahlanong le ho se fetohe (mohlala, marapo a letsoho/libenche tsa mosebetsi), lisebelisoa tsa mananeo tse tsamaellanang (li-interface tse tšepahalang), le mehloli e itseng ea oache bakeng sa li-chip tse lebelo le phahameng.

E fana ka tikoloho e kopaneng ea nts'etsopele (IDEs), ho chesa software, le bakhanni, ho nolofatsa mananeo ka lilaeborari/meralo ea nts'etsopele ho netefatsa ho hlophisoa ha khoutu, ho lokisa liphoso le phetisetso ea data.

Boleng bo balwang ho tsoa ho data ya faele ya lenaneo ho netefatsa botsitso ba data pele le ka mora ho e tjhesa. Ho bapisa ho bontsha lenaneo le nepahetseng; ho se tshwane ho ka bontsha diphoso tsa phetiso kapa diphoso tsa chip.

Sistimi e bohlale ea ho beha leihlo mocheso: MCU e bokella data ho tsoa ho li-sensor tsa mocheso, e laola lifene/li-heater ho latela meeli, ka lenaneo le nolofalletsang ts'ebetso ea data, taolo ea logic le puisano.
