Yini i-I2S Interface?
I-I²S (I-Inter-IC Sound) iyindinganiso yesixhumi esibonakalayo sebhasi ye-elekthronikhi esetshenziselwa ukuxhuma amadivayisi omsindo wedijithali ndawonye, leli zinga laqalwa yi-Philips Semiconductor ngo-1986. Lisetshenziselwa ukudlulisa idatha yomsindo ye-PCM phakathi kwamasekhethi ahlanganisiwe kumadivayisi kagesi.
I-I2S Hardware Interface
1. Ulayini wewashi elincane
Ngokusemthethweni ibizwa ngokuthi "Iwashi Eliqhubekayo le-Serial (SCK)". Ngokuvamile kubhalwe ngokuthi "iwashi elincane (BCLK)".
Okusho ukuthi, idatha ngayinye ehambisana nomsindo wedijithali, i-SCLK ine-pulse.
Imvamisa ye-SCLK = 2 × imvamisa yesampula × inombolo yamabhithi amasampula.
2. Umugqa wewashi wamagama
Eyaziwa ngokusemthethweni ngokuthi "ukukhethwa kwamagama (WS)". [Okujwayele ukubizwa ngokuthi "LRCLK" noma "Ukuvumelanisa Uzimele (FS)".
0 = ishaneli yesokunxele, 1 = ishaneli yesokudla
3. Okungenani umugqa wedatha owodwa ophindwe kabili
Ngokusemthethweni ibizwe ngokuthi "Idatha Yedatha (SD)", kodwa ingabizwa nge-SDATA, SDIN, SDOUT, DACDAT, ADCDAT, njll.
