3.1 Kusankhidwa kwa magetsi
Mphamvu ya 5 V ya AT-START-F407 imatha kuperekedwa kudzera pa chingwe cha USB (mwina kudzera pa cholumikizira cha USB CN6 pa AT-Link-EZ kapena USB cholumikizira CN1 pa AT-START-F407), kapena kudzera pa 5 yakunja. V magetsi (E5V), kapena ndi magetsi akunja a 7 ~ 12 V (VIN) kudzera pa 5V voltage regulator (U1) pa bolodi. Pamenepa, mphamvu ya 5 V imapereka mphamvu ya 3.3 V yofunidwa ndi ma microcontrollers ndi ma peripherals pogwiritsa ntchito 3.3 V vol.tage regulator (U2) pa bolodi.
Pini ya 5 V ya J4 kapena J7 itha kugwiritsidwanso ntchito ngati gwero lamagetsi. Bolodi ya AT-START-F407 iyenera kukhala yoyendetsedwa ndi magetsi a 5 V.
Pini ya 3.3 V ya J4 kapena VDD pin ya J1 ndi J2 itha kugwiritsidwanso ntchito mwachindunji ngati 3.3 V yolowera magetsi. Bolodi ya AT-START-F407 iyenera kukhala yoyendetsedwa ndi magetsi a 3.3 V.
Zindikirani: Pokhapokha ngati 5 V iperekedwa kudzera pa cholumikizira cha USB (CN6) pa AT-Link-EZ, AT-Link-EZ sidzayendetsedwa ndi njira zina zamagetsi.
Pamene bolodi lina logwiritsira ntchito likugwirizanitsidwa ndi J4, mapini a VIN, 5 V ndi 3.3 V angagwiritsidwe ntchito ngati mphamvu yotulutsa; Pini ya 5V ya J7 yogwiritsidwa ntchito ngati mphamvu ya 5 V; pini ya VDD ya J1 ndi J2 yogwiritsidwa ntchito ngati mphamvu ya 3.3 V.
3.2 ID
Pakachitika JP3 OFF (chizindikiro IDD) ndi R13 OFF, amaloledwa kulumikiza ammeter kuyeza kugwiritsa ntchito mphamvu kwa AT32F407VGT7.
- JP3 OFF, R13 ON
Chithunzi cha AT32F407VGT7 (Sinthani zokhazikika, ndipo pulagi ya JP3 siyimayikidwa musanatumizidwe) - JP3 ON, R13 WOTSITSA
Chithunzi cha AT32F407VGT7 - JP3 WOTSITSA, R13 KUCHOKERA
Ammeter iyenera kulumikizidwa kuti iyeze kugwiritsa ntchito mphamvu kwa AT32F407VGT77 (ngati palibe ammeter, AT32F407VGT7 sikhoza kuyendetsedwa).
3.3 Kukonza ndi kukonza zolakwika
3.3.1 Yophatikizidwa ndi AT-Link-EZ
Bungwe lowunika limayika pulogalamu ya Artery AT-Link-EZ ndi chida chowongolera kuti ogwiritsa ntchito athe kukonza/kukonza AT32F407VGT7 pa bolodi la AT-START-F407. AT-Link-EZ imathandizira mawonekedwe a SWD ndipo imathandizira seti ya madoko a COM (VCP) kuti alumikizane ndi USART1_TX/USART1_RX (PA9/PA10) ya AT32F407VGT7. Pamenepa, PA9 ndi PA10 ya AT32F407VGT7 idzakhudzidwa ndi AT-Link-EZ motere:

Kukonzekera kwamphamvu kwamphamvu ndikuwonjezera chotsitsa chotsitsa cha DM9162 XT1 pin kuti athetse kusokonezeka kwa wotchi ya TXCLK. 5. Anachotsa 0 Ω resistor pakati pa zikhomo zosagwiritsidwa ntchito ndi microcontrollers pamene DM9051 ikugwiritsidwa ntchito mu RMII mode. |

Ogula amamvetsetsa ndikuvomereza kuti ogula ali ndi udindo wosankha ndikugwiritsa ntchito zinthu ndi ntchito za Artery.
Zogulitsa ndi ntchito za Artery zimaperekedwa "MOMWE ILIRI" ndipo Artery ilibe zitsimikizo zofotokozera, zonenedwa kapena zovomerezeka, kuphatikiza, popanda malire, zitsimikizo zilizonse zogulitsa, mtundu wokhutiritsa, kusaphwanya, kapena kulimba pazifukwa zina zokhudzana ndi Artery's. katundu ndi ntchito.
Ngakhale zili zosemphana ndi izi, ogula sapeza ufulu, udindo kapena chiwongola dzanja pazinthu zilizonse za Artery kapena maufulu aliwonse aukadaulo omwe ali mmenemo. Zogulitsa ndi ntchito za Artery sizingatanthauze (a) kupatsa ogula, momveka bwino kapena motanthauza, estoppel kapena mwanjira ina, chilolezo chogwiritsa ntchito zinthu ndi ntchito za munthu wina; kapena (b) kupereka chilolezo kwa anthu ena; kapena (c) kutsimikizira malonda ndi ntchito za gulu lina ndi ufulu wake waukadaulo.
Ogula amavomereza kuti zinthu za Artery sizololedwa kuti zigwiritsidwe ntchito, ndipo ogula sangaphatikize, kulimbikitsa, kugulitsa kapena kusamutsa mankhwala a Artery kwa kasitomala aliyense kapena wogwiritsa ntchito kumapeto kuti agwiritsidwe ntchito ngati zofunikira mu (a) zachipatala, zopulumutsa moyo kapena moyo. chipangizo chothandizira kapena dongosolo, kapena (b) chipangizo chilichonse chachitetezo kapena makina ogwiritsira ntchito magalimoto ndi makina aliwonse (kuphatikiza koma osalekeza ndi ma brake agalimoto kapena ma airbag), kapena (c) zida zilizonse zanyukiliya, kapena (d) chipangizo chilichonse chowongolera magalimoto , kugwiritsa ntchito kapena dongosolo, kapena (e) chida chilichonse cha zida, kugwiritsa ntchito kapena dongosolo, kapena (f) chipangizo china chilichonse, kugwiritsa ntchito kapena makina omwe angadziwike kuti kulephera kwa zinthu za Artery monga momwe zimagwiritsidwira ntchito pa chipangizocho, kugwiritsa ntchito kapena dongosolo kungatsogolere. ku imfa, kuvulazidwa kwa thupi kapena kuwonongeka kwakukulu kwa katundu.
