Chotsani IN: Munjira iyi, chowongolera pa bolodi chimachotsedwa ndipo chosokoneza chakunja chimatha kulumikizidwa kuti chiwononge EFM32PG23 pa zida.

Zindikirani: Kuti "Debug IN" igwire ntchito, chowongolera cha board board chiyenera kuyendetsedwa ndi cholumikizira cha Debug USB.

8.2 Kuthetsa vutoli Panthawi Yogwiritsa Ntchito Battery
EFM32PG23 ikakhala yoyendetsedwa ndi batri ndipo J-Link USB ikadali yolumikizidwa, magwiridwe antchito a board amapezeka. Ngati mphamvu ya USB italumikizidwa, njira ya Debug IN imasiya kugwira ntchito.
Ngati njira yothetsera vutoli ikufunika pamene chandamale chikutha mphamvu ina, monga batire, ndipo wowongolera bolodi watsitsidwa, gwirizanitsani mwachindunji ndi GPIO yomwe imagwiritsidwa ntchito pochotsa zolakwika. Izi zikhoza kuchitika mwa kugwirizanitsa ndi zikhomo zoyenera pazitsulo zowonongeka. Zida zina za Silicon Labs zimapereka mutu wa pini wodzipatulira pachifukwa ichi.

9. Kukonzekera kwa Kit ndi Zowonjezera
Zokambirana zosinthira zida mu Simplicity Studio zimakulolani kuti musinthe mawonekedwe a adapter ya J-Link, kukweza firmware yake, ndikusintha masinthidwe ena. Kuti mutsitse Simplicity Studio, pitani ku silabs.com/simplicity.
Pazenera lalikulu la mawonekedwe a Simplicity Studio's Launcher, mawonekedwe owongolera ndi mtundu wa firmware wa adapter yosankhidwa ya J-Link ikuwonetsedwa. Dinani ulalo wa [Sinthani] pafupi ndi iliyonse ya iwo kuti mutsegule zokambirana za kasinthidwe ka zida.

9.1 Kukweza kwa Fimuweya
Kukweza zida za firmware kumachitika kudzera mu Simplicity Studio. Simplicity Studio imangoyang'ana zosintha zatsopano poyambira.
Mutha kugwiritsanso ntchito dialog yosinthira zida kuti mukweze pamanja. Dinani batani la [Sakatulani] pagawo la [Update Adapter] kuti musankhe zolondola file kutha ndi .emz. Kenako, dinani batani la [Install Package].

Schematics, Zojambula Zamsonkhano, ndi BOM

Ma Schematics, zojambula zapagulu, ndi bilu yazinthu (BOM) zimapezeka kudzera pa Simplicity Studio pomwe phukusi lazolemba lakhazikitsidwa. Amapezekanso patsamba la zida pa Silicon Labs webtsamba: http://www.silabs.com/.

Chodzikanira
Silicon Labs ikufuna kupatsa makasitomala zolembedwa zaposachedwa, zolondola, komanso zakuya za zotumphukira zonse ndi ma module omwe amapezeka kwa ogwiritsa ntchito makina ndi mapulogalamu omwe amagwiritsa ntchito kapena akufuna kugwiritsa ntchito zinthu za Silicon Labs. Deta yodziwika bwino, ma module ndi zotumphukira zomwe zilipo, kukula kwa kukumbukira ndi ma adilesi okumbukira zimatanthawuza ku chipangizo chilichonse, ndipo "Zomwe zimaperekedwa" zimatha kusiyanasiyana m'magwiritsidwe osiyanasiyana. Ntchito exampzomwe zafotokozedwa apa ndi zongowonetsera chabe. Silicon Labs ili ndi ufulu wosintha popanda kudziwitsanso zambiri zamalonda, mawonekedwe, ndi mafotokozedwe apa, ndipo sapereka zitsimikizo zakulondola kapena kukwanira kwa zomwe zikuphatikizidwazo. Popanda chidziwitso choyambirira, Silicon Labs ikhoza kusinthira firmware yazinthu panthawi yopanga chifukwa chachitetezo kapena zifukwa zodalirika. Kusintha koteroko sikungasinthe katchulidwe kake kapena mawonekedwe a chinthucho. Ma Silicon Labs sadzakhala ndi ngongole y pazotsatira zogwiritsa ntchito zomwe zaperekedwa pachikalatachi. Chikalatachi sichikutanthauza kapena kupereka chilolezo chopanga kapena kupanga mabwalo aliwonse ophatikizika. Zogulitsazo sizinapangidwe kapena kuloledwa kugwiritsidwa ntchito mkati mwa zida zilizonse za FDA Class III, mapulogalamu omwe chivomerezo cha FDA chimafunikira kapena Life Support Systems popanda chilolezo cholembedwa cha Silicon Labs. "Moyo Wothandizira Moyo" ndi chinthu chilichonse kapena dongosolo lililonse lothandizira kapena kuthandizira moyo ndi / kapena thanzi, zomwe, ngati zitalephera, zikhoza kuyembekezera kuvulala kwakukulu kapena imfa.
