Ibindi bicuruzwa ni umutungo wa ba nyirabyo.
IEEE Igipimo cya 1149.1-1990, Icyambu gisanzwe cya IEEE
TMS320C24x, TMS320C2000, TMS320, na C24x ni ibimenyetso byerekana ibikoresho bya Texas.
Ibisobanuro kuri TMS320LF2407A
Ibikoresho bya TMS320LF240xA na TMS320LC240xA, abanyamuryango bashya ba TMS320C24x ™;ibisekuruza bya digitale ya digitale (DSP) abagenzuzi, nibice bya TMS320C2000 ™;urubuga rwa DSPs.Ibikoresho 240xA bitanga TMS320 yongerewe imbaraga ™;Igishushanyo mbonera cya DSP ya C2xx yibanze ya CPU kubiciro bidahenze, imbaraga nke, hamwe nubushobozi bwo gutunganya cyane.Ibikoresho byinshi byateye imbere, byashyizwe kuri moteri ya moteri na moteri igenzura, byahujwe no gutanga umugenzuzi umwe-chip DSP.Mugihe code-ihuza na C24x iriho ™;Ibikoresho bya DSP bigenzura, 240xA itanga imikorere yo gutunganya (40 MIPS) hamwe nurwego rwo hejuru rwo kwishyira hamwe.Reba igice cya TMS320x240xA Incamake yibikoresho kubikoresho byihariye.
Igisekuru cya 240xA gitanga umurongo wubunini bwa memoire hamwe na peripheri zitandukanye zujuje ibisabwa kugirango zuzuze igiciro / imikorere isabwa na porogaramu zitandukanye.Ibikoresho bya flash byamagambo agera kuri 32K bitanga ikiguzi-cyogusubiramo igisubizo cyibicuruzwa.Ibikoresho bya 240xA bitanga ijambo ryibanga "kode yumutekano" rifite akamaro mukurinda kwigana kutemewe kode yimitungo ibitswe kuri chip Flash / ROM.Menya ko ibikoresho bishingiye kuri Flash bikubiyemo ijambo 256-boot boot ROM kugirango byorohereze porogaramu.Umuryango wa 240xA urimo kandi ibikoresho bya ROM byuzuye pin-to-pin bihuye na Flash bagenzi babo.
Ibikoresho byose 240xA bitanga byibura icyiciro kimwe cyumuyobozi wateguwe neza kugirango bigenzurwe na moteri ya moteri hamwe na porogaramu zihindura ingufu.Ubushobozi bwiyi module burimo hagati- na / cyangwa guhuza-ibisekuruza bya PWM, porogaramu ishobora gukoreshwa kugirango wirinde kurasa-amakosa, hamwe no kugereranya-kuri-guhinduranya.Ibikoresho hamwe nabashinzwe ibyabaye byombi bifasha moteri nyinshi na / cyangwa guhinduranya hamwe na 240xA DSP igenzura.Hitamo ibipapuro bya EV byahawe "kwinjiza-kwuzuza" umuzenguruko, bigabanya pin-trigger itabishaka.
Imikorere-yo hejuru, 10-bit analog-to-digitale (ADC) ifite byibuze igihe cyo guhindura 375 ns kandi itanga imiyoboro igera kuri 16 yinjiza.Ubushobozi bwa autosequensique ya ADC butuma ntarengwa 16 ihinduka ibaho mugihe kimwe cyo guhindura nta CPU irenze.
Imigaragarire y'itumanaho (SCI) ihuriweho nibikoresho byose kugirango itange itumanaho ridahuje nibindi bikoresho muri sisitemu.Kuri sisitemu isaba itumanaho ryiyongera, 2407A, 2406A, 2404A, na 2403A itanga 16-bit synchronous serial peripheral interface (SPI).2407A, 2406A, na 2403A zitanga imiyoboro y'itumanaho (CAN) module y'itumanaho yujuje 2.0B.Kugirango ugabanye ibikoresho byoroshye, pin ikora nayo irashobora kugereranywa nkibisanzwe-byinjiza / ibisohoka (GPIOs).
Kugirango uhindure igihe cyiterambere, JTAG-yubahiriza scan-ishingiye ku kwigana yashyizwe mubikoresho byose.Ibi bitanga ubushobozi budasubirwaho burigihe busabwa kugirango ucyure sisitemu yo kugenzura imibare.Suite yuzuye ya code-generation ibikoresho kuva C ikusanya kugeza inganda-isanzwe ya Code Composer Studio ™;debugger ishyigikira uyu muryango.Benshi mubateza imbere igice cya gatatu ntabwo batanga ibikoresho byiterambere byurwego rwibikoresho gusa, ahubwo banatanga igishushanyo mbonera cya sisitemu hamwe niterambere ryiterambere.
