AEM muaj peev xwm ntsuas qhov tam sim no ntawm 0.1 µA txog 47 mA. Rau cov tam sim no siab dua 250 µA, AEM yog qhov tseeb hauv 0.1 mA. Thaum ntsuas tam sim no qis dua 250 µA, qhov tseeb nce mus rau 1 µA. Txawm hais tias qhov tseeb tseeb yog 1 µA nyob rau hauv sub 250 µA ntau, AEM muaj peev xwm txheeb xyuas cov kev hloov pauv ntawm kev siv tam sim no tsawg li 100 nA. AEM tsim 6250 tam sim no samples per ob.
On-Board Debugger
Cov Khoom Siv PG23 Pro muaj qhov sib xyaw ua ke debugger, uas tuaj yeem siv los rub tawm code thiab debug EFM32PG23. Ntxiv rau qhov programming EFM32PG23 ntawm cov khoom siv, tus debugger kuj tuaj yeem siv los ua haujlwm thiab debug sab nraud Silicon Labs EFM32, EFM8, EZR32, thiab EFR32 li.
Lub debugger txhawb peb qhov sib txawv debug interfaces siv nrog Silicon Labs li:
- Serial Wire Debug, uas yog siv nrog tag nrho cov khoom siv EFM32, EFR32, thiab EZR32
- JTAG, uas tuaj yeem siv nrog EFR32 thiab qee cov khoom siv EFM32
- C2 Debug, uas yog siv nrog EFM8 li
Txhawm rau kom paub meej qhov kev debugging, siv qhov tsim nyog debug interface rau koj lub cuab yeej. Lub debug connector ntawm lub rooj tsavxwm txhawb tag nrho peb hom no.
8.1 Debug Hom
Txhawm rau tsim cov khoom siv sab nraud, siv qhov kev debug txuas txuas mus rau lub rooj tsav xwm lub hom phiaj thiab teeb tsa hom kev debug rau [Tawm]. Tib lub connector kuj tseem siv tau los txuas rau lwm qhov debugger rau EFM32PG23 MCU ntawm cov khoom siv los ntawm kev teeb tsa hom kev debug rau [In].
Xaiv hom kev debug nquag ua tiav hauv Simplicity Studio.
Debug MCU: Nyob rau hauv hom no, lub hauv paus debugger txuas nrog EFM32PG23 ntawm cov khoom siv.
Debug OUT: Nyob rau hauv hom no, lub on-board debugger yuav siv tau los debug ib tug txhawb Silicon Labs ntaus ntawv mounted rau ib tug kev cai board.
Debug hauv: Nyob rau hauv hom no, lub on-board debugger raug txiav thiab ib qho kev debugger sab nraud tuaj yeem txuas rau debug EFM32PG23 ntawm cov khoom siv.
Nco tseg: Rau "Debug IN" ua haujlwm, cov khoom siv tswj hwm yuav tsum tau siv los ntawm Debug USB connector.
8.2 Debugging Thaum lub roj teeb ua haujlwm
Thaum lub EFM32PG23 yog roj teeb-powered thiab J-Link USB tseem txuas nrog, lub on-board debug functionality muaj. Yog tias USB fais fab tuag lawm, lub Debug IN hom yuav tsis ua haujlwm.
Yog tias kev nkag mus debug yuav tsum tau thaum lub hom phiaj khiav tawm ntawm lwm lub zog, xws li lub roj teeb, thiab lub rooj tsav xwm tswj tau siv zog, ua kev sib txuas ncaj qha rau GPIO siv rau kev debugging. Qhov no tuaj yeem ua tiav los ntawm kev txuas mus rau cov pins tsim nyog ntawm cov ntaub qhwv tawm. Qee cov khoom siv Silicon Labs muab tus pin header rau lub hom phiaj no.
9. Cov khoom siv teeb tsa thiab hloov kho dua tshiab
Cov khoom siv teeb tsa kev sib tham hauv Simplicity Studio tso cai rau koj hloov J-Link adapter debug hom, hloov kho nws cov firmware, thiab hloov lwm yam teeb tsa. Txhawm rau rub tawm Simplicity Studio, mus rau silabs.com/simplicity.
Nyob rau hauv lub qhov rais tseem ceeb ntawm Simplicity Studio's Launcher foundations, qhov kev debug hom thiab firmware version ntawm cov xaiv J-Link adapter tau pom. Nyem qhov [Hloov] txuas ntawm ib sab ntawm lawv los qhib cov khoom siv sib tham.
9.1 Txhim kho Firmware
Kev hloov kho cov khoom siv firmware yog ua tiav los ntawm Simplicity Studio. Simplicity Studio yuav cia li kuaj xyuas qhov hloov tshiab tshiab ntawm kev pib.
Koj tseem tuaj yeem siv cov khoom siv configuration dialog rau kev hloov kho phau ntawv. Nyem qhov [Xaiv qhov] khawm hauv ntu [Hloov kho Adapter] xaiv qhov raug file xaus hauv .emz. Tom qab ntawd, nyem lub pob [Install Package].
Schematics, Assembly Drawings, thiab BOM
Schematics, sib dhos kos duab, thiab daim nqi ntawm cov ntaub ntawv (BOM) muaj los ntawm Simplicity Studio thaum cov khoom siv cov ntaub ntawv tau teeb tsa. Lawv kuj muaj los ntawm cov khoom siv nplooj ntawv ntawm Silicon Labs webqhov chaw: http://www.silabs.com/.
Kit Revision History thiab Errata
11.1 Revision History
Kev kho cov khoom siv tuaj yeem pom tau luam tawm ntawm lub thawv ntawv ntawm cov khoom siv, raws li tau teev tseg hauv daim duab hauv qab no.
