Nordic ichangobva kuburitsa chigadzirwa chitsva cheBluetooth audio portfolio, iyo Nordic nRF5340 Audio Development Kit. Iyi DK yekuteerera inosanganisira zvese zvinodiwa kubatsira vanogadzira kutora mukana wemhando yepamusoro yekurira, kuderera kwesimba rekushandisa uye isina waya stereo ekuwedzera yeBluetooth LE Audio.
Nordic inozivisa nRF5340 Audio Development Kit, chikuva chekugadzira chekukurumidza kusimudzira kweBluetooth® LE Audio zvigadzirwa. Iyo nRF5340 ndiyo yekutanga pasirese isina waya SoC ine maviri Arm® Cortex®-M33 processors, yakanakira LE Audio uye zvimwe zvakaomarara zveInternet yezvinhu (IoT) application.
Iyo Bluetooth Special Interest Group (SIG) inotsanangura LE Audio se "ramangwana remhepo isina waya". Iyi tekinoroji yakavakirwa pane yakaderera-kuoma kwekutaurirana codec LC3, inosimudzira kune yakaderera-yakaomarara subband codec (SBC) inoshandiswa neClass Audio.
LC3 inova nechokwadi chekuti LE Audio ine mhando yepamusoro yekuteerera uye hupenyu hurefu hwebhatiri kupfuura Classic Audio mune zvese zvekushandisa. Kuyedzwa kwekuteerera kwakanyanya kwakaratidza kuti iyo LC3 inopa zvirinani odhiyo mhando pane SBC pachiyero chakafanana chemuenzaniso pamareti ese emuenzaniso, uye inoburitsa yakaenzana kana iri nani odhiyo mhando pahafu yewaya isina waya data.
Yakaderera data mareti chinhu chakakosha mukuderedza kushandiswa kwesimba muLE Audio zvigadzirwa. LE Audio inounzawo Yechokwadi Wireless Stereo (TWS) uye zvimwe zvinhu zvitsva kune isina waya odhiyo maapplication, kusanganisira Audio Kugovera.
Iyo Audio DK's musimboti nRF5340 SoC inosanganisa yakakwira-inoshanda application processor ine yakazara programmable yekupedzisira-yakaderera-simba network processor yekunyatsoita simba uye kuita kwepamusoro muhuviri-musimboti architecture. Iyo 128 MHz Arm Cortex-M33 application processor ine 1 MB yeflash uye 512 KB ye RAM, ichiita kuti ive yakanakira kubata tsika maapplication uye maodhiyo macodec akadai seLC3.
Iyo 64 MHz Arm Cortex-M33 network processor ine 256 KB yeflash memory uye 64 KB ye RAM, uye ine simba-yakagadziridzwa kumhanya Nordic Bluetooth LE Audio RF protocol software. Iyo nRF Batanidza SDK ndeye nRF5340 SoC yekuvandudza chikuva inopa nRF5340 Audio DK bhodhi nhanho rutsigiro uye inotsigira LE Audio, Bluetooth Low Energy, Thread uye mamwe maapplication.
Pamusoro peiyo nRF5340 SoC, iyo Audio DK inoratidzira Nordic's nPM1100 simba manejimendi IC (PMIC) uye Cirrus Logic's CS47L63 odhiyo yedhijitari chiratidzo processor (DSP).
Iyo nPM1100 inoratidzira inoshanda zvakanyanya inogadziriswa bhati regulator uye yakabatanidzwa bhatiri charger inosvika 400mA yekuchaja ikozvino mune diki fomu chinhu, ichiiita yakanakira PMIC yenzvimbo-inomanikidzirwa application seTWS earbuds. Iyo CS47L63 inoratidzira yakakwira-inoshanda DAC uye mutsauko wekubuda mutyairi akagadziridzwa kuti abatanidzwe zvakananga kune ekunze mahedhifoni anorema eearbud zvigadzirwa zvine mono uye zvakanangana nemutauri zvinobuda chete.
