Kodi I2S Interface ndi chiyani?
I²S (Inter-IC Sound) ndi mawonekedwe amagetsi amtundu wa basi omwe amagwiritsidwa ntchito polumikiza zida zomvera zama digito palimodzi, mulingo uwu udayambitsidwa koyamba ndi Philips Semiconductor mu 1986. Amagwiritsidwa ntchito kusamutsa data ya PCM pakati pa mabwalo ophatikizika pazida zamagetsi.
I2S Hardware Interface
1. Mzere wotchipa pang'ono
Amatchedwa "Continuous Serial Clock (SCK)". Nthawi zambiri amalembedwa ngati "bit clock (BCLK)".
Ndiye kuti, deta iliyonse yofanana ndi audio ya digito, SCLK ili ndi pulse.
Mafupipafupi a SCLK = 2 × sampuli pafupipafupi × kuchuluka kwa ma sampling bits.
2. Mzere wa wotchi ya mawu
Amatchedwa "kusankhiratu mawu (WS)". [Zomwe zimatchedwa "LRCLK" kapena "Frame Sync (FS)".
0 = njira yakumanzere, 1 = njira yakumanja
3. Mzere umodzi wochuluka wa data
Amatchedwa "Serial Data (SD)", koma amatha kutchedwa SDATA, SDIN, SDOUT, DACDAT, ADCDAT, etc.
Chithunzi cha nthawi ya I²S
I2S mawonekedwe: Bluetooth module
