Izama ukufunda i-EEPROM kumafrikhwensi ewashi aphansi kanye/noma ngevolumu ephansitagi-e ingase ibangele idatha engavumelekile.

Ukulungisa Inkinga / Ukusebenza

Lesi sici saziwa njengokuncika ekushiseni kodwa asikaze sibonakale. Imihlahlandlela inikezwa ukushisa kwegumbi, kuphela.

I-Timer Counter 1 ukukhiqizwa kokukhishwa kwe-PWM ku-OC1B - XOC1B akusebenzi kahle

Isikhathi se-Counter1 PWM sokukhipha i-OC1B-XOC1B asisebenzi kahle. Kuleso simo kuphela lapho amabithi wokulawula, i-COM1B1 ne-COM1B0 zikumodi efanayo ne-COM1A1 ne-COM1A0, ngokulandelana, i-OC1B-XOC1B ekhishwe isebenza kahle.

Ukulungisa Inkinga / Ukusebenza uzungeze

Ukuphela kokusebenza ukusebenzisa isethingi yokulawula efanayo ku-COM1A [1: 0] naku-COM1B [1: 0] control bits, bona ithebula 14- 4 kushidi ledatha. Inkinga isilungiselwe i-Tiny45 rev.

Ukusetshenziswa kwamandla okuphezulu kakhulu

I-DebugWIRE ikhulula ukuxhumana lapho umuntu oyedwa engena kokuphazamisayo

I-PLL ayikhiyi

Ukufundwa kwe-EEPROM kusuka kukhodi yohlelo lokusebenza akusebenzi ku-Lock Bit Mode 3

Ukufundwa kwe-EEPROM kungase kuhluleke ekunikezeni okuphansi voltage / imvamisa yewashi ephansi

Ukusetshenziswa kwamandla okuphezulu kakhulu

Izimo ezintathu zizoholela ekusetshenzisweni kwamandla okuphezulu kakhulu. Lezi izi:

Iwashi langaphandle likhethwa ngamafiyuzi, kepha i-I / O PORT isanikwe amandla njengokukhipha.

I-EEPROM ifundwa ngaphambi kokufaka amandla phansi.

I-VCC ingu-4.5 volts noma ngaphezulu.

Umshwana wokuzihlangula: Imininingwane ekulo mbhalo inikezwe mayelana nemikhiqizo ye-Atmel. Ayikho ilayisensi, eshiwo noma eshiwo, nge-estoppel noma ngenye indlela, kunoma yiliphi ilungelo lempahla yengqondo elinikezwa yilo mbhalo noma mayelana nokudayiswa kwemikhiqizo ye-Atmel. NGAPHANDLE NJENGOBA KUBEKWE EMIBANDELA NEZIMBANDELA ZOKUTHENGISA EZISE-ATMEL WEBI-SITE, I-ATMEL AYITHATHI ISIBOPHO FUTHI IZINIKELA IZIQINISEKISO, EZISHIYILEYO NOMA EZISEMTHETHWENI EMIKHIQIZO YAYO ESIHLANGANISA NEMIKHIQIZO YAYO, KODWA AYIMALI KANYE, ISIQINISEKISO SOKUTHENGISWA, UKULUNGA NGOKUBEKA UHLANGANISO. AKUKHO MCIMBI I-ATMEL AYIYOKUBA NESIBOPHO NGANOMA YIKUPHI OKUQONDILE, OKUQONDILE, OKULANDELAYO, OKUJEZISAYO, OKUKHETHEKILE NOMA OKWENZAKALELAYO (KUHLANGANISA, NGAPHANDLE KOMKHAWULO, UMONAKALO WOKULAHLEKILE KANYE NEZINZUZO, UKUPHAZAMISEKA KWEBHIZINISI, NOMA UKUHLUPHEKA KOLWAZI) LO MBHALO, NOMA I-ATMEL YALULEKISWA NGAKHONA OKUNGENZEKA KULOMONA OMLOMO.

I-Atmel ayenzi izethulo noma iziqinisekiso maqondana nokunemba noma ukuphelela kokuqukethwe kulo mbhalo futhi inelungelo lokwenza izinguquko ezincazelweni nasezincazelweni zemikhiqizo nganoma yisiphi isikhathi ngaphandle kwesaziso. I-Atmel ayenzi noma yikuphi ukuzibophezela ekubuyekezeni ulwazi oluqukethwe lapha. Ngaphandle kokuthi kuhlinzekwe ngenye indlela, imikhiqizo ye-Atmel ayifanele, futhi ngeke isetshenziswe ezinhlelweni zezimoto. Imikhiqizo ye-Atmel ayihlosiwe, ayigunyaziwe, noma ayigunyaziwe ukuthi isetshenziswe njengezingxenye ezinhlelweni ezihloselwe ukusekela noma ukusekela ukuphila.
