O le a le I2S Interface?
I²S (Inter-IC Sound) ose fa'aoga fa'akomepiuta fa'akomepiuta fa'aoga fa'aoga fa'aoga mo le fa'afeso'ota'i fa'atasi masini leo fa'akomepiuta, o lenei fa'ata'ita'iga na fa'alauiloa muamua e Philips Semiconductor i le 1986. E fa'aaogaina e fa'aliliuina ai fa'amatalaga leo PCM i le va o feso'ota'iga tu'ufa'atasi i masini fa'aeletoroni.
I2S Meafaigaluega Fa'afeso'ota'i
1. Bit uati laina
Fa'aigoa aloa'ia "Uati Fa'asologa Fa'aauau (SCK)". E masani ona tusia o le "bit clock (BCLK)".
O lona uiga, o vaega ta'itasi o fa'amaumauga e fetaui ma le leo numera, SCLK o lo'o i ai se pulupulu.
Ole taimi ole SCLK = 2 × faʻataʻitaʻiga faʻataʻitaʻiga × numera o sampling bits.
2. Upu uati laina
Fa'aigoa aloa'ia o le "upu filifilia (WS)". [E masani ona taʻua o le "LRCLK" poʻo le "Frame Sync (FS)".
0 = alavai agavale, 1 = alavai taumatau
3. Le itiiti ifo ma le tasi laina fa'amatalaga fa'atele
Fa'aigoa aloa'ia "Serial Data (SD)", ae mafai ona ta'ua SDATA, SDIN, SDOUT, DACDAT, ADCDAT, ma isi.
Fa'asologa o taimi ole I²S
I2S fa'aoga: Bluetooth module
