Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is the Micromite suite likely to include a SPI client ability in future ?Edited by chronic 2017-08-10

Do you mean slave?

No, I have never heard of that need.

I thought of making some modules that could be used as a SPI device but after testing that for a while i preferred to use I2C instead. In all MY cases I2C is fast enough and also has the bonus of only using two pins.
Microblocks. Build with logic.

Yes sorry I meant slave, just asking as it has a promise
at increasing connectivity. I have an arduino slave working but
it is a bit limited .

because of the (potential) speeds involved, I am guessing the hardware would have to support this mode. I don't have access to the datasheet atm but it would be a very tall order to emulate 10MHz bus in software. That said, I agree it would definitely add another feather to the uM's cap - I currently have no use for it but in multi-micromite devices it would open up a new world of de-centralised control. I have done this on a very small scale using CSub Serial ports but SPI is cleaner
