LE Audio Code Migration Amafunikira zida
Malo oyesera ndi chilengedwe
Malo oyesera: BT631D (NRF5340)
Mtundu wa SDK: NCS2.3.0
Zowonongeka Zamalonda

Muyenera kukhazikitsa zomvera za LE
- LC3 encoding ndi decoding
- Le transmission encoding data
- Thandizo la ntchito zingapo zosinthira
- Thandizani CIS unicast audio ntchito
- Thandizani ntchito ya audio ya BIS
Ikani zomwe zili mu sitaki ya protocol
Njira zotsatirira ndi ma flowchart zikuwonetsedwa pansipa
- Chipata chimalandira zomvera kuchokera kugwero la audio.
- The gateway imagwiritsa ntchito zomvera m'malo ake ogwiritsira ntchito ndikutumiza deta kudzera mugawo la pulogalamu:
- Wolandirayo amatumiza zomvera zosungidwa ku network kernel subsystem (wowongolera).
- Pulogalamuyi imatumiza deta ya audio LE ku wailesi ya hardware ndikuitumiza ku chipangizo chamutu.
- Chomverera m'makutu chimalandira ma encoded audio data pa network core.
- Netiweki kernel subsystem (wowongolera) imatumiza zomvera zojambulidwa kwa LE host pa core application.
- Mafoni am'mutu amakonza zomvera pamapulogalamu awo, omwe amatumiza deta kudzera mugawo la pulogalamu:
- Decoded audio decoded imatumizidwa ku hardware audio output kudzera I2S.
Mfundo za chidwi
Le audio pakadali pano ndiukadaulo watsopano wokhala ndi mayankho okhwima okhwima pamsika, uinjiniya wovuta, ndi zovuta zambiri zomwe ziyenera kuthetsedwa!
Chidule
Kusamuka kwa ma code a LE ndizovuta kwambiri, koma zotsatira zoyesa gawo la BT631D zimakhala zabwino kwambiri zitasamuka. Ogwiritsa amene amafunikira ntchitoyi akhoza kulumikizana ndi gulu la Feasycom!
