S/PDIF implementation

[romain-viollette]

Is it useful to add a SPDIF connection on the audio shield?
There is 3 wires to connect:
(A10) -> (connector) -> (signal name)
PB3 -> GPIO_3:6 -> SPDIF_MCLK
PB12 -> GPIO_3:22 -> SPDIF_DI
PB13 -> GPIO_3:24 -> SPDIF_DO

How to connect them and where?

ok for a connector with SPDIF_DI and SPDIF_DO and Ground

There is a problem, the pin GPIO_3:22 (I2S_DI/AC97_DI/SPDIF_DI/PB12) is already used for I2S, so I can't connect SPDIF_DI

For the moment only the SPDIF_DO on pin GPIO_3:24 (SPI2_CS1/SPDIF_DO/PB13) will be connected.
