Re: mpd: output to SPI ?

I see.... So, I should implement: - Enable() or Open(), to initialise my SPI HW interface; - Disable, or Close(), to clean it; - Play(), to get and enqueue a chunk of data for SPI output (keeping track, inside my driver, of microcontroller fill status) - Delay(), returning non-zero until I need/can ...

Re: mpd: output to SPI ?

My plugin should provide following features: - supply an output channel to mpd (mpd will write blocks of data, which will be stored in a circular queue of RAM buffers) - block transfer to host microcontroller via SPI; - handshaking with host microcontroller, that will report back it's buffer filling...

mpd: output to SPI ?

Hi all, I would like to send mpd audio output to an external microcontroller (for further processing and I2S output). I'm planning to use SPI (around 10Mbps) for stream output on MOSI line and would like to use the read line (MISO) to receive feedback from my microcontroller in order to trim mpd out...
