Kedu ihe bụ I2S Interface?
I²S (Inter-IC Sound) bụ ọkọlọtọ serial ụgbọ ala eletrọnịkị ejiri maka ijikọ ngwaọrụ dijitalụ ọnụ, Philips Semiconductor webatara ọkọlọtọ a na 1986. A na-eji ya nyefee data ọdịyo PCM n'etiti sekit agbakwunyere na ngwaọrụ eletrọnịkị.
I2S Ngwa ngwa Interface
1. Ahịrị elekere Bit
A na-akpọ ya "Oghere Usoro Oghere Usoro (SCK) na-aga n'ihu". A na-edekarị ya ka "bit clock (BCLK)".
Ya bụ, ntakịrị data nke ọ bụla dabara na ọdịyo dijitalụ, SCLK nwere usu.
Ugboro nke SCLK = 2 × ugboro nlele × ọnụọgụ nlele ibe n'ibe.
2. Ahịrị elekere okwu
A maara nke ọma dị ka "nhọrọ okwu (WS)". [A na-akpọkarị "LRCLK" ma ọ bụ "Mmekọrịta Frame (FS)".
0 = ọwa aka ekpe, 1 = ọwa aka nri
3. Ọ dịkarịa ala otu ahịrị data multiplexed
A na-akpọkarị "Serial Data (SD)", mana enwere ike ịkpọ SDATA, SDIN, SDOUT, DACDAT, ADCDAT, wdg.
