Yintoni i-I2S Interface?
I-I²S (Isandi se-Inter-IC) ngumgangatho wojongano lwebhasi ye-elektroniki esetyenziselwa ukudibanisa izixhobo ezivakalayo zedijithali kunye, lo mgangatho waziswa okokuqala yiPhilips Semiconductor ngo-1986.
I2S Hardware Interface
1. Umgca wewotshi encinci
Ngokusesikweni ebizwa ngokuba yi "Continuous Serial Clock (SCK)". Ngokuqhelekileyo ibhalwe njenge "bit clock (BCLK)".
Oko kukuthi, i-bit nganye yedatha ehambelana nomsindo wedijithali, i-SCLK ine-pulse.
I-frequency ye-SCLK = 2 × i-sampling frequency × inani leebhithi zesampulu.
2. Umgca wewotshi yegama
Eyaziwa ngokusesikweni njenge "ukhetho lwamagama (WS)". [Edla ngokubizwa ngokuba yi "LRCLK" okanye "Ungqamaniso lweSakhelo (FS)".
0 = isitishi sasekhohlo, 1 = isitishi sasekunene
3. Ubuncinci umgca wedatha ophindwe kabini
Ngokusemthethweni ebizwa ngokuba yi "Serial Data (SD)", kodwa ingabizwa ngokuba yi-SDATA, SDIN, SDOUT, DACDAT, ADCDAT, njl.
