Incazelo yebhodi lomsindo le-Qualcomm ne-HIFI

Uhlolojikelele lwe-HIFI-PCBA

I-RISCV-DSP chip+Qualcomm QCC3x/5x uchungechunge lwe-Bluetooth, esekela izivumelwano ze-Bluetooth APTX,
I-APTX-HD, APTX-LL, APTX-AD, LDAC, LHDC; Imisebenzi ye-peripheral isekela ama-USB flash drive,
SPDIF, KGB, amakhadi e-SD, nezikrini ze-LED

Ukwakheka kozimele kwe-HIFI-PCBAmain

Incazelo Yomsebenzi we-HIFI-PCBA

1. Ibhodi eliyinhloko. Khetha ibhodi eliyinhloko ngokwezidingo zephrojekthi.
2. Isixhumi esibonakalayo sokunikezwa kwamandla kwe-VBAT nokushintshwa kwamandla.
3. Ukuhlolwa kwamanje. Lapho kuhlolwa i-chip VBAT yamanje, kuyadingeka ukuxhuma i-multimeter kuyo
   uchungechunge. kulesi sixhumi esibonakalayo, Uma kungadingekile ukukala okwamanje, i-cap emfushane kufanele ibe
   kufakiwe.
4. Isixhumi esibonakalayo se-USB. a) Njengesixhumi esibonakalayo sokulanda se-chip; b) Lapho ulungisa iphutha le-USB
   umsebenzi we-chip, ingasetshenziswa njengesixhumi esibonakalayo sedivayisi ye-USB, njenge-USB flash disk
   isikhombimsebenzisi
5. Isixhumi esibonakalayo sekhadi le-SD/TF. Ingaphambili liyisixhumi esibonakalayo sekhadi le-SD, futhi ngemuva kunesixhumi esibonakalayo sekhadi le-TF.
6. Ukhiye we-PWR. Ixhunywe kuphinikhodi ye-PWR, ingafinyelela imisebenzi efana nale
   PP/PWK.VOL+/NEXT, VOL -/PREV, njll. ngokuya ngokucushwa kwesoftware.
7. Ukhiye we-ADKEY. Xhuma ku-chip GPIOx, eyi-ADC CHx. Ngokusho kwesoftware
   ukucushwa, imisebenzi efana ne-PP, VOL+/NEXT, VOL -/PREV ingenziwa.
8. Ukukhetha i-MIC ebhodini. Khetha indlela ye-MICL noma ye-MICR ye-chip ngephini. Qaphela
   ukuthi akuwona wonke amamodeli asekela i-MICL ne-MICR.
9. Okukhipha i-Onboard PA Lapho ulungisa iphutha lomsebenzi wesipika, ungawudlala uphele
   onboard PA ukuze ulalele umphumela wokulungisa iphutha.
10. Okokufaka komthombo womsindo we-AUX. Imithombo yomsindo yangaphandle ingafakwa ngalesi sixhumi esibonakalayo futhi
    ithunyelwe ku-chip ukuze icutshungulwe.
11. Isixhumi esibonakalayo esikhipha umsindo. I-DAC-VBF ihambisana nesixhumi esibonakalayo esingakwesokunxele, kanye ne-DAC-CAP
    ihambisana nesixhumi esibonakalayo esifanele.
12. Isikrini sokubonisa sedijithali. Isikhathi sokubonisa, ivolumu, isimo,

Incazelo ye-algorithm ye-Hifi

Ukusebenzisa umtapo wezincwadi we-NatureDSP njengomtapo wolwazi ohlobene nekhompyutha yesayensi ephumelelayo
I-Candence HIF14 yesikhulumi, ihlanganiswe endaweni yethu yesikhulumi futhi yengezwa ku
iphrojekthi.kuhlanganise namamojula we-algorithm afana ne-ftt, fir, iir, math, matinv, nesithombe. Lezi
imisebenzi yekhompuyutha yesayensi evame ukusetshenziswa ilungiselelwa ngaphakathi kusetshenziswa imanuwaliHIF14
imiyalelo, esebenza kahle kakhulu futhi ewusizo kakhulu ekuthuthukiseni amandla okubala.
