I've seen hacks using the I2S parallel mode to shift out data and bit-bang various protocol,
so I'm trying to figure out if it's possible and how to best achieve it.
What would be the best (and hopefully easy) approach?
I2S Peripheral in parallel mode (or RMT?) to send data to multiple (bitbang) SPI DACs

I'm working on a project where besides a I2S audio DAC on I2S0, I will need to update (using I2S1) 4 or more 2-ch MCP4822 DACs with DC outputs at audio rate and all in-sync from an ISR filling in the data.
