Chotsani IN: Munjira iyi, chowongolera pa bolodi chimachotsedwa ndipo chowongolera chakunja chimatha kulumikizidwa kuti chichotse EFM8BB50 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
EFM8BB50 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 ikutha mphamvu ina, monga batire, ndipo chowongolera cha board chatsitsidwa, pangani kulumikizana mwachindunji ndi ma GPIO omwe amagwiritsidwa ntchito pochotsa, omwe amawonekera pamapadi ophulika.
Kukonzekera kwa Kit ndi Kukweza
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 [Sinthani] ulalo womwe uli pafupi ndi chilichonse mwa zoikamo izi kuti mutsegule zokambirana za kasinthidwe ka zida.
9.1 Kukweza kwa Fimuweya
Mutha kukweza zida za firmware kudzera pa 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 pomaliza in.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: silabs.com.
Kit Revision History ndi Errata
