- 0 Ω useto lwesixhasi lubonisiwe kwiTheyibhile yesi-3.
- I-SPIM mayicinywe kwaye i-JP8 enye-piece jumper kufuneka ikhethe i-I/O, kungenjalo i-PA8 kunye ne-PB6 ayinakusetyenziswa.
3.12.2 LQFP100 I/O isidibanisi esongezelelweyo
I-extension connectors i-J1 kunye ne-J2 inokudibanisa i-AT-START-F407 kwiprototype yangaphandle / ibhodi yokupakisha. Iizibuko ze-I/O ze-AT32F407VGT7 ziyafumaneka kwezi ziqhagamshelo zolwandiso. I-J1 kunye ne-J2 inokulinganiswa kunye ne-probe ye-oscilloscope, i-logic analyzer okanye i-voltmeter.
Phawula 1: Cwangcisa i-R17 OFF ukuba kuyimfuneko ukunika amandla nge-J2 pin_21 VREF+ ye-AT-START-F407 kunye nonikezelo lwamandla lwangaphandle,

Imbali yohlaziyo
Uluhlu 5. Imbali yohlaziyo loxwebhu
| Umhla | Uhlaziyo | Iinguqu |
| 2020.2.14 | 1.0 | Ukukhutshwa kokuqala |
| 2020.5.12 | 1.1 | 1. Ukulungiswa kwe-LED3 ukuya kumthubi 2. Iqhagamshele i-TXEN ye-DM916 kwi-PB11_E, ayidityaniswanga ngokuthe ngqo kwi-AT32F407 3. Uhlengahlengiso lwe-51 Ω isixhasi senxeba locingo phakathi kwe-AT32F407 kunye ne-DM9162 ukuya kwi-0 Ω ibhulorho ukuze i-AT32F40 iqhawulwe ngokupheleleyo. ukusuka kwiDM9162. |
| 2020.9.23 | 1.11 | 1. Utshintshe ikhowudi yohlaziyo yolu xwebhu ukuya kwidijithi ezi-3, ezimbini zokuqala ze-AT-START inguqulelo yehardware, kunye neyokugqibela yoguqulelo loxwebhu. 2. Ukongeza iCandelo 3.9. |
| 2020.11.20 | 1.20 | 1. Ukuhlaziya inguqu ye-AT-Link-EZ kwi-1.2, kwaye ulungelelanise imiqolo emibini yeempawu ze-CN7, kwaye uguqule i-silkscreen. 2. Ukuguqulwa kwe-silkcreen ye-CN2 ngokuhambelana nezixhobo zophuhliso lwe-Artery. 3. Kongezwe i-GND i-pin pin ring ukuququzelela umlinganiselo. 4. Ukulungiswa kwamandla okulungiselelwe kwaye yongeza i-resistor yokutsalwa phantsi kwe-DM9162 XT1 pin ukuphelisa ukuphazamiseka kwiwashi ye-TXCLK. 5. Isuse i-0 Ω resistor phakathi kwezikhonkwane ezingasetyenziswanga kunye ne-microcontrollers xa i-DM9051 isetyenziswa kwimodi ye-RMII. |
ISAZISO ESIBALULEKILEYO - NCEDA UFUNDE NGOKUQONELELE
Abathengi bayaqonda kwaye bayavuma ukuba abathengi banoxanduva kuphela lokukhetha kunye nokusetyenziswa kweemveliso kunye neenkonzo ze-Artery.
Iimveliso kunye neenkonzo ze-Artery zibonelelwa "NJENGOKO KUNJALO" kwaye uMthambo awuboneleli ngeziqinisekiso ezicacileyo, ezichaziweyo okanye ezisemthethweni, kubandakanya, ngaphandle komda, naziphi na iziqinisekiso ezichaziweyo zokurhweba, umgangatho owanelisayo, ukungaphulwa komthetho, okanye ukomelela kwinjongo ethile ngokubhekiselele kwi-Artery's. iimveliso kunye neenkonzo.
Nangona kukho nantoni na echaseneyo, abathengi abafumani lungelo, itayitile okanye inzala kuyo nayiphi na imveliso kunye neenkonzo ze-Artery okanye nawaphi na amalungelo epropathi enomgangatho ophezulu wokuqonda aqulethwe kuyo. Akukho mcimbi uya kuthi iimveliso kunye neenkonzo ze-Artery zithathwe njengoku (a) ukunika abathengi, ngokucacileyo okanye ngentsingiselo, i-estoppel okanye ngenye indlela, ilayisenisi yokusebenzisa iimveliso kunye neenkonzo zomntu wesithathu; okanye (b) ukunika ilayisensi umntu wesithathu ngamalungelo obunini bomgangatho wengqondo; okanye (c) ukuqinisekisa iimveliso kunye neenkonzo zomntu wesithathu kunye namalungelo alo obunini bomgangatho ophezulu wokuqonda.
Abathengi bayavuma ukuba iimveliso ze-Artery azigunyaziswanga ukuba zisetyenziswe njengoko, kwaye abathengi abayi kudibanisa, bakhuthaze, bathengise okanye badlulisele nayiphi na imveliso ye-Artery kuye nawuphi na umthengi okanye umsebenzisi wokugqibela ukuze asetyenziswe njengamacandelo abalulekileyo (a) naluphi na unyango, ukusindisa ubomi okanye ubomi. isixhobo esixhasayo okanye inkqubo, okanye (b) nasiphi na isixhobo sokhuseleko okanye inkqubo kuso nasiphi na isicelo semoto nendlela (kubandakanywa kodwa ingaphelelanga kwiinkqubo zeziqhoboshi zemoto okanye kwiingxowa zomoya), okanye (c) naziphi na izixhobo zenyukliya, okanye (d) nasiphi na isixhobo solawulo lwezithuthi zomoya. , usetyenziso okanye inkqubo, okanye (e) nasiphi na isixhobo sezixhobo, usetyenziso okanye inkqubo, okanye (f) nasiphi na esinye isixhobo, usetyenziso okanye inkqubo apho kubonwa kwangaphambili ukuba ukusilela kweemveliso zoMsebenzi njengoko kusetyenziswa kweso sixhobo, ukusetyenziswa okanye inkqubo kuya kukhokelela ekubeni ukusilela kweemveliso zoMzimba njengoko kusetyenziswe kweso sixhobo. ukufa, ukwenzakala emzimbeni okanye umonakalo omkhulu wepropathi.
