- 0 Ω ukulungiselelwa kwe-resistor kukhonjiswe kuThebula lesi-3.
- I-SPIM kufanele ivaliwe futhi i-JP8-piece-piece jumper kufanele ikhethe i-I/O, ngaphandle kwalokho i-PA8 ne-PB6 azikwazi ukusetshenziswa.
3.12.2 LQFP100 I/O isixhumi sesandiso
Izixhumi zesandiso i-J1 ne-J2 zingaxhuma i-AT-START-F407 ku-prototype/packing board yangaphandle. Izimbobo ze-I/O ze-AT32F407VGT7 ziyatholakala kulezi zixhumi zesandiso. I-J1 ne-J2 nayo ingalinganiswa nge-probe ye-oscilloscope, i-logic analyzer noma i-voltmeter.
Qaphela 1: Setha u-R17 OFF uma kudingekile ukuze unikeze amandla nge-J2 pin_21 VREF+ ye-AT-START-F407 ngamandla angaphandle nangaphandle,

Umlando wokubuyekeza
Ithebula 5. Umlando wokubuyekeza idokhumenti
| Usuku | Buyekeza | Izinguquko |
| 2020.2.14 | 1.0 | Ukukhishwa kokuqala |
| 2020.5.12 | 1.1 | 1. I-LED3 eshintshiwe yabaphuzi 2. Ixhume i-TXEN ye-DM916 ku-PB11_E, ayixhunyanisiwe ngokuqondile ne-AT32F407 3. Kulungiswe i-51 Ω resistor wire-nxeba phakathi kwe-AT32F407 ne-DM9162 kuya ku-0 Ω ibhuloho ukuze i-AT32F40 inqanyulwe ngokuphelele. kusuka ku-DM9162. |
| 2020.9.23 | 1.11 | 1. Kushintshwe ikhodi yokubuyekeza yale dokhumenti yaba amadijithi angu-3, amabili okuqala enguqulo yehadiwe ye-AT-START, neyokugcina yenguqulo yedokhumenti. 2. Kwengezwe Isigaba 3.9. |
| 2020.11.20 | 1.20 | 1. Ibuyekeze inguqulo ye-AT-Link-EZ yaba ngu-1.2, futhi yalungisa imigqa emibili yamasignali e-CN7, futhi yashintsha isikrini sikasilika. 2. Kulungiswe i-silkcreen ye-CN2 ngokuvumelana namathuluzi okuthuthukisa i-Artery. 3. Kwengezwe indandatho yephinikhodi yokuhlola ye-GND ukuze kube lula ukulinganisa. 4. Isakhiwo samandla esithuthukisiwe futhi yengeza iphinikhodi yokudonsela phansi ye-DM9162 XT1 ukuze kuqedwe ukuphazamiseka ewashini le-TXCLK. 5. Kukhishwe i-resistor engu-0 Ω phakathi kwezikhonkwane ezingasetshenzisiwe nezilawuli ezincane lapho i-DM9051 isebenza ngemodi ye-RMII. |
ISAZISO ESIBALULEKILE - SICELA UFUNDE NGOKUQONDA
Abathengi bayaqonda futhi bayavuma ukuthi abathengi banesibopho kuphela sokukhethwa nokusetshenziswa kwemikhiqizo namasevisi e-Artery.
Imikhiqizo namasevisi e-Artery ahlinzekwa “NJENGOBA INGABE” futhi i-Artery ayihlinzeki ngeziqinisekiso ezivezwayo, ezishiwo noma ezingokomthetho, okuhlanganisa, ngaphandle komkhawulo, noma yiziphi iziqinisekiso ezisikiselwayo zokuthengiselana, ikhwalithi egculisayo, ukungephulwa komthetho, noma ukufaneleka ngenjongo ethile maqondana ne-Artery. imikhiqizo namasevisi.
Ngaphandle kwanoma yini ephambene, abathengi abalitholi ilungelo, isihloko noma inzalo kunoma yimiphi imikhiqizo namasevisi e-Artery nanoma imaphi amalungelo empahla yengqondo equkethwe kuyo. Akukho mcimbi lapho imikhiqizo namasevisi e-Artery ehlinzekiwe ayohunyushwa ngokuthi (a) ukunikeza abathengi, ngokucacile noma ngokusikisela, i-estoppel noma ngenye indlela, ilayisensi yokusebenzisa imikhiqizo namasevisi ezinkampani zangaphandle; noma (b) ngokunikeza ilayisensi amalungelo empahla yengqondo yabantu besithathu; noma (c) eqinisekisa imikhiqizo namasevisi enkampani yangaphandle namalungelo ayo empahla yengqondo.
Abathengi ngalokhu bayavuma ukuthi imikhiqizo ye-Artery ayigunyaziwe ukuthi isetshenziswe, futhi abathengi ngeke bahlanganise, bakhuthaze, bathengise noma badlulisele noma yimuphi umkhiqizo we-Artery kunoma iliphi ikhasimende noma umsebenzisi wokugcina ukuze usetshenziswe njengezingxenye ezibalulekile (a) kunoma yikuphi ukwelashwa, ukusindisa impilo noma ukuphila. idivayisi yokwesekwa noma isistimu, noma (b) noma iyiphi idivayisi yokuphepha noma isistimu kunoma yiluphi uhlelo lwezimoto kanye nendlela (okuhlanganisa kodwa kungagcini nje ngamabhuleki ezimoto noma amasistimu e-airbag), noma (c) noma yiziphi izinsiza zenuzi, noma (d) noma iyiphi idivayisi yokulawula ukuhamba emoyeni. , uhlelo noma uhlelo, noma (e) noma iyiphi idivayisi yezikhali, uhlelo lokusebenza noma uhlelo, noma (f) noma iyiphi enye idivayisi, uhlelo lokusebenza noma uhlelo lapho kubonakala khona ukuthi ukwehluleka kwemikhiqizo yoMcibisholo njengoba isetshenziswa kuleyo divayisi, isicelo noma uhlelo kungaholela ukufa, ukulimala komzimba noma ukulimala okuyinhlekelele kwempahla.
