Dear all, thank you for taking the time to read this post.
I have been working with the FEZ (Domino and mini) for some time and have a couple of questions that I need some help on.
The first is to the GHI team:
is it possible for me to purchase a FEZ mini that has not been built with the male pins on the back? I have a project that requires it to be flat and have been painstakingly removing the pins for it to work as I need a flatter profile for the device.
The second question is a little bit more technical:
I have two power sources that need to be read into the FEZ mini. Both power sources are continuous and variable in voltage but always below the 3.3v input cap. The question is, can the FEZ mini read both input loads simultaneously? ie can it take two loads in at the same time and read them both accurately with no noise?
I ask as, when I have the system running and each load is read independently, the signal data is read correctly as expected. But when both signals are used at the same time, it seems to become very noisy! is this as expected and should I attach an op-amp onto the input voltages and control their flow in an alternating fashion?
Thanks for any information you can offer.
