A software defined S/PDIF library that allows you to trasnmit or receive S/PDIF data via xCORE ports. S/PDIF is a digital data streaming interface. The components in the libary are controlled via C using the XMOS multicore extensions (xC) and provides both a S/PDIF receiver and transmitter.
- Supports stereo S/PDIF receive up to sample rates up to 96KHz
- Supports stereo S/PDIF transmit up to 192KHz
- configuration: Transmit
- globals: buffered out port:32 p_spdif_tx = XS1_PORT_1B; in port p_mclk_in = XS1_PORT_1E; clock clk_audio = XS1_CLKBLK_1;
- locals: chan c;
- fn: spdif_tx(p_spdif_tx, c);
- pins: 1
- ports: 1 (1-bit)
- cores: 1
- configuration: Receive
- globals: port p_spdif_rx = XS1_PORT_1F; clock audio_clk = XS1_CLKBLK_1;
- locals: streaming chan c;
- fn: spdif_rx(c, p_spdif_rx, audio_clk, 48000);
- pins: 1
- ports: 1 (1-bit)
- cores: 1
