Hey guys,
I've been looking into something like this for a while as well. One thing that caught my eye was this pin converter shield for the UNO/Leo to go between the old pinout and 1.0
Something like this could be implemented with logic converters between the connection points. This could also leads in some other interesting directions as well:
- Being able to select/designate individual pins as 5v or 3.3v logic
- Integrating dynamic pin assignment so the pinout could be adaptable to older shields configurations
- And if you really wanted to get crazy, you could even wire the whole thing up to be driven by an integrated IC so you just add a library to your sketch and assign the pinout and voltage in software.
- And since I've already gone way out in left field, to complete the prefect conversion shield, add either an IC to linearly scale the analog inputs or a separate 5v 12 or 16 bit ADC
EDIT: Just read the post about the GTL2000 and it got me thinking there has got to be a chip that could route pins and shift logic levels... Yup.
Thoughts?
