4.3 I-Debug Connector (DBG)
Isidibanisi se-debug sisebenza ngeenjongo ezimbini, ngokusekwe kwimowudi ye-debug, enokusekwa kusetyenziswa iSitudiyo esilula. Ukuba imowudi ethi "Debug IN" ikhethiwe, isidibanisi sivumela i-debugger yangaphandle ukuba isetyenziswe kunye ne-EFM32PG23 ekwibhodi. Ukuba i "Debug OUT" imowudi ikhethiwe, umdibaniso uvumela ikiti ukuba isetyenziswe njenge-debugger kwithagethi yangaphandle. Ukuba imo ye-"Debug MCU" (engagqibekanga) ikhethiwe, isidibaniso sibekwe sodwa kujongano lwe-debug yabo bobabini umlawuli webhodi kunye nesixhobo ekujoliswe kuso ebhodini.
Ngenxa yokuba esi sidibanisi sitshintshelwa ngokuzenzekelayo ukuxhasa iindlela zokusebenza ezahlukeneyo, sifumaneka kuphela xa isilawuli sebhodi sinikwe amandla (i-J-Link intambo ye-USB ixhunyiwe). Ukuba i-debug ukufikelela kwisixhobo esijoliswe kuyo iyadingeka xa umlawuli webhodi engenamandla, oku kufuneka kwenziwe ngokudibanisa ngokuthe ngqo kwizikhonkwane ezifanelekileyo kwi-header yokuqhawula. I-pinout yesiqhagamshelo ilandela eyomgangatho we-ARM Cortex Debug 19-pin.
I-pinout ichazwe ngokweenkcukacha ngezantsi. Qaphela ukuba nangona isinxibelelanisi sixhasa i-JTAG ukongeza kuthotho lwe Debug, ayithethi ngokuyimfuneko ukuba ikhithi okanye isixhobo ekujoliswe kuso siyakuxhasa oku.
Nangona i-pinout ihambelana ne-pinout ye-ARM Cortex Debug isidibanisi, ezi azihambelani ngokupheleleyo njengoko i-pin 7 ikhutshwa ngokwasemzimbeni kwi-Cortex Debug isidibanisi. Ezinye iintambo zineplagi encinci ethintela ukuba ingasetyenziswa xa kukho le phini. Ukuba oku kunjalo, susa iplagi, okanye usebenzise intambo eqhelekileyo eyi-2×10 1.27 mm ethe ngqo endaweni yoko.

Advanced Energy Monitor
7.1 Ukusetyenziswa
Idatha ye-Advanced Energy Monitor (AEM) iqokelelwa ngumlawuli webhodi kwaye ingaboniswa yi-Energy Pro.filer, ifumaneka ngeSitudiyo esilula. Ngokusebenzisa i-Energy Profiler, ukusetyenziswa kwangoku kunye nomthamotagi-e inokulinganiswa kwaye idibaniswe nekhowudi yangempela esebenza kwi-EFM32PG23 ngexesha langempela.
7.2 Ithiyori yokuSebenza
Ukulinganisa ngokuchanekileyo yangoku ukusuka kwi-0.1 µA ukuya kwi-47 mA (114 dB dynamic range), ingqiqo yangoku ampI-lifier isetyenziswa kunye nenzuzo emibinitage. Ingqondo yangoku ampisisitshisi silinganisa umthamotage ukuwisa phezu resistor series encinane. Inzuzo stage phambili ampiyawuxhasa lo mqulutage kunye nezicwangciso ezimbini ezahlukeneyo zokufumana ukufumana uluhlu lwangoku lwangoku. Utshintsho phakathi kwezi zintlu zimbini lwenzeka malunga nama-250 µA. Ukuhluzwa kweDijithali kunye ne-avareji yenziwa ngaphakathi komlawuli webhodi phambi kwe-sampLes ithunyelwa kumazwe angaphandle kwi-Energy Profiler isicelo.
Ngexesha lokuqaliswa kwekiti, ulungelelwaniso oluzenzekelayo lwe-AEM luyenziwa, oluhlawulela impazamo ye-offset ngengqiqo. ampabaphilayo.
7.3 Ukuchaneka nokuSebenza
I-AEM iyakwazi ukulinganisa imisinga kuluhlu lwe-0.1 µA ukuya kwi-47 mA. Kwimisinga engaphezulu kwe-250 µA, i-AEM ichanekile ngaphakathi kwe-0.1 mA. Xa ulinganisa imisinga engaphantsi kwama-250 µA, ukuchaneka kuyanda ukuya kwi-1 µA. Nangona ukuchaneka ngokupheleleyo yi-1 µA kuluhlu lwe-sub 250 µA, i-AEM iyakwazi ukubona utshintsho kusetyenziso lwangoku oluncinci njenge-100 nA. I-AEM ivelisa i-6250 yangokuampngaphantsi ngesekhondi.
Idebugger ekwibhodi
I-PG23 Pro Kit iqulethe i-debugger edibeneyo, engasetyenziselwa ukukhuphela ikhowudi kunye nokulungisa i-EFM32PG23. Ukongeza kwiprogram ye-EFM32PG23 kwikhithi, i-debugger ingasetyenziselwa ukucwangcisa kunye nokulungisa izixhobo zangaphandle ze-Silicon Labs EFM32, EFM8, EZR32, kunye ne-EFR32 izixhobo.
Idebugger ixhasa ujongano lwedebug ezintathu ezahlukeneyo ezisetyenziswa nezixhobo zeSilicon Labs:
- Uthotho lwe-Wire Debug, esetyenziswa kuzo zonke izixhobo ze-EFM32, EFR32, kunye ne-EZR32
- JTAG, enokusetyenziswa kunye ne-EFR32 kunye nezinye izixhobo ze-EFM32
- C2 Debug, esetyenziswa ngezixhobo ze-EFM8
Ukuqinisekisa ulungiso oluchanekileyo, sebenzisa ujongano olufanelekileyo lokulungisa isixhobo sakho. Isidibanisi sokulungisa ingxaki ebhodini sixhasa zonke ezi ndlela zontathu.
8.1 Iindlela zokulungisa iimpazamo
Ukucwangcisa izixhobo zangaphandle, sebenzisa isidibaniso solungiso lweempazamo ukudibanisa kwibhodi ekujoliswe kuyo kwaye usete indlela yolungiso kwi [Phama]. Kwaesi sidibanisi sisenokusetyenziswa ukuqhagamshela i-debugger yangaphandle kwi-EFM32PG23 MCU kwikhithi ngokuseta imowudi yolungiso kwi [In].
Ukukhetha imowudi yolungiso esebenzayo yenziwa kwiSitudiyo esilula.
Debug MCU: Kule ndlela, i-debugger ekwibhodi iqhagamshelwe kwi-EFM32PG23 kwikhithi.
Debug OUT: Kule ndlela, i-debugger ekwibhodi ingasetyenziselwa ukulungisa ingxaki yesixhobo se-Silicon Labs esixhonywe kwibhodi yesiko.
Debug IN: Kule ndlela, i-debugger ekwibhodi inqanyuliwe kwaye i-debugger yangaphandle inokudityaniswa ukulungisa i-EFM32PG23 kwikhithi.
Phawula: Ukuze i-“Debug IN” isebenze, isilawuli sebhodi yekhithi kufuneka sinikwe amandla nge-Debug USB connector.
8.2 Ukulungiswa kweempazamo Ngexesha lokuSebenza kwebhetri
Xa i-EFM32PG23 inamandla ebhetri kwaye i-J-Link USB isaqhagamshelwe, ukusebenza kwe-debug kwibhodi kuyafumaneka. Ukuba amandla e-USB avaliwe, imowudi ye-Debug IN iza kuyeka ukusebenza.
Ukuba ukufikelela kwe-debug kuyafuneka xa ithagethi ibaleka komnye umthombo wamandla, njengebhetri, kwaye umlawuli webhodi wehliselwe amandla, yenza uqhagamshelo oluthe ngqo kwiGPIO esetyenziselwa ukulungisa ingxaki. Oku kunokwenziwa ngokudibanisa nezikhonkwane ezifanelekileyo kwiipads zokuqhawula. Ezinye iikhithi zeSilicon Labs zibonelela ngentloko yepini ezinikeleyo kule njongo.
9. Ulungelelwaniso lweKhithi kunye noPhuculo
Incoko yababini yoqwalaselo lwekhithi kwiSitudiyo esiLula ikuvumela ukuba utshintshe imowudi yokulungisa i-adapter ye-J-Link, uphucule i-firmware yayo, kwaye utshintshe ezinye izicwangciso zoqwalaselo. Ukukhuphela iSitudiyo esilula, yiya ku silabs.com/simplicity.
Kwifestile ephambili yombono weSitudiyo esiLula, imowudi yokulungisa iimpazamo kunye noguqulelo lwe-firmware ye-adapter ye-J-Link ekhethiweyo iyaboniswa. Cofa i [Shintsha] ikhonkco ecaleni kwayo nayiphi na kuzo ukuvula incoko yababini yoqwalaselo lwekhithi.
9.1 Uphuculo lweFirmware
Ukuphucula i-firmware yekiti kwenziwa ngeSitudiyo esilula. ISitudiyo esilula siya kukhangela ngokuzenzekelayo uhlaziyo olutsha xa uqalwa.
Ungasebenzisa kwakhona uqwalaselo lwekiti yencoko yababini kuhlaziyo lwezandla. Cofa i [Khangela] iqhosha kwindawo ethi [Hlaziya iAdapter] ukukhetha okulungileyo file ephela ngo.emz. Emva koko, cofa iqhosha elithi [Fakela ipakethe].
I-Schematics, iMizobo yeNdibano, kunye ne-BOM
I-Schematics, imizobo yendibano, kunye ne-bill of materials (BOM) ziyafumaneka ngeSitudiyo esilula xa iphakheji yamaxwebhu ekhithi ifakiwe. Zikwafumaneka kwiphepha lekhithi kwiiLabhu zeSilicon webindawo: http://www.silabs.com/.
