HIFI-PCBAInkcazelo yomsebenzi

1. Ibhodi engundoqo. Khetha ibhodi engundoqo ngokweemfuno zeprojekthi.
2. VBAT ujongano lombane kunye nokutshintsha amandla.
3. Uvavanyo lwangoku. Xa uvavanya i-chip VBAT yangoku, kuyimfuneko ukudibanisa i-multimeter
   uthotho. kolu jongano, Xa kungekho mfuneko yokulinganisa yangoku, ikepusi emfutshane kufuneka ibe
   ifakiwe.
4. Ujongano lwe-USB. a) Njengojongano lokhuphelo lwetshiphu; b) Xa ulungisa i-USB
   umsebenzi wetshiphu, ingasetyenziswa njengojongano lwesixhobo se-USB, njengediski ye-USB flash
   U mboniso.
5. Ujongano lwekhadi le-SD/TF. Umphambili ujongano lwekhadi le-SD, kwaye ngasemva lujongano lwekhadi leTF.
6. PWR isitshixo. Iqhagamshelwe kwi-pin ye-PWR ye-chip, inokufezekisa imisebenzi efana nayo
   I-PP/PWK.VOL+/ELANDELAYO, I-VOL -/PREV, njl. ngokobumbeko lwesoftware.
7. ADKEY isitshixo. Qhagamshela kwitshiphu yeGPIOx, eyi-ADC CHx. Ngokutsho kwesoftware
   uqwalaselo, imisebenzi efana nePP, VOL+/NEXT, VOL -/PREV inokuphunyezwa.
8. Ebhodini ukhetho lwe-MIC. Khetha indlela ye-MICL okanye ye-MICR yetshiphu ngephini. Phawula
   ukuba ayizizo zonke iimodeli ezixhasa i-MICL kunye ne-MICR.
9. Onboard PA imveliso Xa debugging umsebenzi wesithethi, ungakwazi ukuyidlala ngaphandle
   kwibhodi ye-PA ukumamela isiphumo solungiso.
10. Igalelo lomthombo womsindo we-AUX. Imithombo yomsindo yangaphandle inokufakwa ngolu jongano kunye
    ithunyelwe kwitshiphu ukuze iqwalaselwe.
11. Ujongano lwemveliso yomsindo. I-DAC-VBF ihambelana nojongano lwasekhohlo, kunye neDAC-CAP
    ihambelana nojongano oluchanekileyo.
12. Digital display screen. Ixesha lokubonisa, umthamo, ubume,

Inkcazo ye-Algorithm ye-Hifi

Ukusebenzisa ithala leencwadi leNatureDSP njengethala leencwadi elinxulumene nekhompyutha esebenzayo yenzululwazi kwi
Iqonga leCandence HIF14, liye laqulunqwa kwiqonga lethu kwaye longezwa kwi
project.kuquka iimodyuli zealgorithm ezifana nefft, fir, iir, math, matinv, kunye nomfanekiso. Ezi
imisebenzi yekhompuyutha esetyenziswa ngokuqhelekileyo iphuculwe ngaphakathi kusetyenziswa manualHIF14
imiyalelo, esebenza kakuhle kwaye iluncedo kakhulu ekuphuculeni amandla okubala.
