[PD] Pduino, firmata and SPI

is there a firmata vertion with at least basic master to slave SPI support?
what is the fastest way to be able to use digipots with Pure Data?

both digipots and digital to analog converters need the SPI protocol to operate
and it is still not implemented in firmata!!!


i tried using RC low pass filters for DAC conversion but the quality is terrible.

are there digipots that could operate with PWM instead of the SPI protocol?


or a DAC chip that will convert PWM to an analog voltage without the SPI protocol?
i found myself trapped with this problem.


will firmata ever have SPI support?


regards
r.y
