Qualcomm ndi HIFI Audio Board Kufotokozera

HIFI-PCBA General Overview

RISCV-DSP chip + Qualcomm QCC3x/5x mndandanda wa Bluetooth, wothandizira ma protocol a Bluetooth APTX,
APTX-HD, APTX-LL, APTX-AD, LDAC, LHDC; Ntchito zotumphukira zimathandizira ma drive a USB flash,
SPDIF, KGB, makadi a SD, ndi zowonera za LED

HIFI-PCBAKufotokozera Ntchito

1. Core board. Sankhani bolodi lalikulu malinga ndi zosowa za polojekiti.
2. VBAT magetsi mawonekedwe ndi kusintha mphamvu.
3. Mayeso apano. Poyesa chip VBAT panopa, m'pofunika kulumikiza multimeter mu
   mndandanda. ku mawonekedwe awa, Pamene sikoyenera kuyeza panopa, kapu lalifupi ayenera kukhala
   kulowetsedwa.
4. USB mawonekedwe. a) Monga Download mawonekedwe kwa Chip; b) Pamene debugging ndi USB
   Chip chikhoza kugwiritsidwa ntchito ngati mawonekedwe a chipangizo cha USB, monga USB flash disk
   Mawonekedwe.
5. SD/TF khadi mawonekedwe. Kutsogolo ndi mawonekedwe a SD khadi, ndipo kumbuyo ndi mawonekedwe a TF khadi.
6. PWR chinsinsi. Yolumikizidwa ndi pini ya PWR ya chip, imatha kukwaniritsa ntchito monga
   PP/PWK.VOL+/NEXT, VOL -/PREV, etc. malinga ndi kasinthidwe mapulogalamu.
7. ADKEY key. Lumikizani ku chip GPIOx, chomwe ndi ADC CHx. Malinga ndi mapulogalamu
   kasinthidwe, ntchito monga PP, VOL+/NEXT, VOL -/PREV zitha kuchitika.
8. Pa bolodi kusankha MIC. Sankhani njira ya MICL kapena MICR ya chip kudzera pa pini. Zindikirani
   kuti si mitundu yonse yomwe imathandizira MICL ndi MICR.
9. Kutulutsa kwa Onboard PA Mukakonza ntchito ya speaker, mutha kuyisewera monse
   onboard PA kuti mumvetsere zosokoneza.
10. AUX audio source input. Zomvera zakunja zitha kulowetsedwa kudzera mu mawonekedwe awa ndi
    yotumizidwa ku chip kuti ikakonzedwe.
11. Audio linanena bungwe mawonekedwe. DAC-VBF imagwirizana ndi mawonekedwe akumanzere, ndi DAC-CAP
    zimagwirizana ndi mawonekedwe oyenera.
12. Chiwonetsero cha digito. Nthawi yowonetsera, voliyumu, mawonekedwe,

Kufotokozera kwa Hifi Algorithm

Kugwiritsa ntchito laibulale ya NatureDSP ngati laibulale yokhudzana ndi makompyuta asayansi aluso pa
Candence HIF14 nsanja, idapangidwa papulatifomu yathu ndikuwonjezeredwa ku
project.including algorithm modules monga fft, fir, ir, math, matinv, ndi image. Izi
ntchito zamakompyuta zomwe zimagwiritsidwa ntchito nthawi zambiri zimakonzedwa mkati pogwiritsa ntchito manualHIF14
malangizo, omwe ndi othandiza kwambiri komanso othandiza kwambiri pakuwongolera mphamvu zamagetsi.
