Umdwebo weBlock

Umfanekiso we-3-1 Block Diagram

Umongo we-AVR uhlanganisa isethi yemiyalo ecebile namarejista okusebenza ngezinjongo ezijwayelekile ezingu-32. Wonke amarejista angama-32 axhumeke ngqo ku-Arithmetic Logic Unit (ALU). Amarejista amabili azimele angafinyelelwa ngomyalelo owodwa owenziwe emjikelezweni wewashi owodwa. Isakhiwo esiwumphumela sisebenza kahle kakhulu ngekhodi kuyilapho sizuza okuphumayo ngokushesha okuphindwe kashumi kunama-microcontrollers avamile e-CISC. Uhlelo luhlanganisa ivolumu yangaphakathitagUmthethonqubo kanye nokuphathwa kwamandla okuthuthukile. Ihlukaniswa ukuvuza okuncane kwamanje ivumela isikhathi sokusebenza esandisiwe kusuka kubhethri.
I-transceiver yomsakazo iyisisombululo se-ZigBee esihlanganiswe ngokugcwele sisebenzisa inani elincane lezingxenye zangaphandle. Ihlanganisa ukusebenza kahle kwe-RF nezindleko eziphansi, usayizi omncane kanye nokusetshenziswa okuphansi kwamanje. I-transceiver yomsakazo ihlanganisa i-crystal stabilized fractional-N synthesizer, transmitter kanye ne-receiver, kanye nokucubungula okugcwele kwe-Direct Sequence Spread Spectrum Signal (DSSS) ngokusabalalisa nokusabalalisa.

Imodi yokunciphisa umsindo ye-ADC imisa i-CPU nawo wonke amamojula e-I/O ngaphandle kwesibali sikhathi esingavumelanisi ne-ADC, ukuze kuncishiswe umsindo oshintshayo phakathi nokuguqulwa kwe-ADC. Kumodi yokulinda, i-oscillator ye-RC iyasebenza ngenkathi yonke idivayisi ilele. Lokhu kuvumela ukuqalisa okusheshayo kuhlanganiswe nokusetshenziswa kwamandla okuphansi. Kumodi Yokulinda Okunwetshiwe, kokubili i-RC oscillator eyinhloko nesibali-sikhathi esingavumelanisiwe kuyaqhubeka nokusebenza.
Ukunikezwa kwamandla okujwayelekile kwesilawuli esincane esinewashi le-CPU elibekwe ku-16MHz kanye ne-transceiver yomsakazo yezifunda ezibaluleke kakhulu iboniswa kuMfanekiso 3-2 ngezansi.

Umfanekiso 3-2 I-transceiver yomsakazo kanye ne-microcontroller (16MHz) ihlinzeka okwamanje

Amandla okukhiphayo okudlulisa asethwe kubukhulu. Uma i-transceiver yomsakazo ikumodi ye-SLEEP i-current ichithwa isilawuli esincane se-AVR kuphela.
Kumodi Yokulala Okujulile wonke amabhulokhi edijithali amakhulu angenazo izimfuneko zokugcinwa kwedatha anqanyuliwe emnikelweni oyinhloko ohlinzeka ngokuvuza kwamanje okuncane kakhulu. Isibali sikhathi se-Watchdog, ikhawunta yophawu lwe-MAC ne-oscillator engu-32.768kHz ingalungiselelwa ukuqhubeka nokusebenza.

Idivayisi yakhiwe kusetshenziswa ubuchwepheshe bememori obungaguquki obuphezulu be-Atmel.
I-On-chip ISP Flash ivumela inkumbulo yohlelo ukuthi ihlelwe kabusha ohlelweni ngokusebenzisa isixhumi esibonakalayo se-SPI, ngohlelo oluvamile lwenkumbulo olungaguquki, noma ngohlelo lwe-on-chip boot olusebenza kumongo we-AVR. Uhlelo lokuqalisa lungasebenzisa noma yisiphi isikhombimsebenzisi ukulanda uhlelo lohlelo lokusebenza kumemori ye-Flash yesicelo.
Isofthiwe esesigabeni sokuqalisa se-Flash izoqhubeka nokusebenza ngesikhathi isigaba se-Flash sohlelo sibuyekezwa, sinikeze ukusebenza kwangempela kwe-Read-While-Write. Ngokuhlanganisa i-8 bit RISC CPU ne-In-System Self-Programmable Flash ku-chip ye-monolithic, i-Atmel ATmega2564/1284/644RFR2 iyi-microcontroller enamandla enikeza isisombululo esivumelana nezimo kakhulu nesibizayo ezinhlelweni eziningi zokulawula ezishumekiwe.
I-ATmega2564/1284/644RFR2 AVR isekelwa ngohlelo oluphelele lwamathuluzi okuthuthukiswa kwesistimu okuhlanganisa: I-C compiler, ama-macro assemblers, isilungisi iphutha/izifanisi zohlelo, ama-emulators angaphakathi kwesekethe, nezinsiza zokuhlola.

Okokufaka kwe-RF okungapheli okungu-50Ω kuyaguqulwa. kuya ku-100Ω umehluko wembobo ye-RF impedance usebenzisa i-Balun B1. Ama-capacitor C1 kanye ne-C2 ahlinzeka ngokuhlanganisa kwe-AC okokufaka kwe-RF embobeni ye-RF, i-capacitor C4 ithuthukisa ukufanisa.

Umfanekiso 4-1. I-Basic Application schematic (iphakheji yamaphini angu-48)

Ama-bypass capacitor okunikezwa kwamandla kagesi (CB2, CB4) axhunywe kuphinikhodi yokunikezela ye-analog yangaphandle (EVDD, pin 44) kanye nephinikhodi yangaphandle yedijithali (DEVDD, pin 16). I-capacitor C1 inikeza ukuhlanganisa kwe-AC okudingekayo kwe-RFN/RFP.
Izikhonkwane ezintantayo zingabangela ukushabalaliswa kwamandla amaningi (isb. phakathi nokukhanyisa). Kufanele zixhunywe emthonjeni ofanele. I-GPIO ngeke ixhumeke endaweni ephansi noma kugesi ngokuqondile.
Izikhonkwane zokufaka zedijithali i-TST ne-CLKI kufanele zixhunywe. Uma iphinikhodi ye-TST ingasoze yasetshenziswa ingaxhunywa ku-AVSS kuyilapho iphinikhodi engasetshenziswa i-CLKI ingase ixhunywe ku-DVSS (bona isahluko esithi “Amaphini Angasetshenzisiwe”).
Ama-Capacitor CB1 kanye ne-CB3 angama-bypass capacitor e-analog ehlanganisiwe nevolumu yedijithalitage-regulators ukuqinisekisa ukusebenza okuzinzile kanye nokwenza ngcono ukungavikeleki komsindo.
Ama-Capacitor kufanele abekwe eduze kakhulu nezikhonkwane futhi kufanele abe nokumelana okuphansi nokuxhumeka okuphansi kwe-inductance emhlabathini ukuze kuzuzwe ukusebenza okuhle kakhulu.

Ikristalu (XTAL), ama-capacitor okulayisha amabili (CX1, CX2), kanye nesekhethi yangaphakathi exhunywe kumaphini XTAL1 kanye ne-XTAL2 yakha i-crystal oscillator engu-16MHz ye-transceiver engu-2.4GHz. Ukuze kuzuzwe ukunemba okungcono kakhulu nokuzinza kwereferensi yereferensi, amandla amakhulu e-parasitic kufanele agwenywe. Imigqa yekristalu kufanele ihanjiswe ibe mfushane ngangokunokwenzeka futhi ingabi seduze namasignali edijithali e-I/O. Lokhu kuyadingeka ikakhulukazi kumamodi Wesilinganiso Sedatha Ephezulu.
Ikristalu engu-32.768 kHz exhunywe kumandla aphansi angaphakathi (sub 1µA) crystal oscillator inikeza inkomba yesikhathi esizinzile yawo wonke amamodi wamandla aphansi okuhlanganisa i-32 Bit IEEE 802.15.4 I-Symbol Counter (“Isibali Sophawu Lwe-MAC”) kanye nohlelo lokusebenza lwewashi lesikhathi sangempela lisebenzisa i-asynchronous i-timer T/C2 (“Isibali-sikhathi/Isibali2 esine-PWM kanye Nokusebenza Okungavumelani”).
Isamba somthamo we-shunt ohlanganisa i-CX3, i-CX4 akufanele idlule u-15pF kuwo womabili amaphini.
Ukunikezwa kwamandla okuphansi kakhulu kwe-oscillator kudinga ukuhlelwa ngokucophelela kwe-PCB futhi noma iyiphi indlela yokuvuza kufanele igwenywe.
I-Crosstalk kanye nemisebe kusukela ekushintsheni amasignali edijithali kuya kumaphini ekristalu noma amaphini e-RF angehlisa izinga lokusebenza kwesistimu. Kunconywa ukuhlelwa kwezilungiselelo zamandla edrayivu amancane esignali yokuphumayo kwedijithali (bona “DPDS0 – Porter Strength Register 0”).
