I am a novice to electronics and micro-controllers.
I am also a novice to programming in C though I have programmed plugins for 3ds Max in maxscript which seems pretty similar.
My project involves programming My Canon Camera via a USB host
similar to this project:
It also involves a number of sensors that use SPI bus
and some that Use I2C
I wanted also to use a LiPO battery to charge while plugged in and then discharge when in use
Finally I plan to use e-paper as output device with some LED's to light my project in low light.
I was planning to use the Mini PRO 3.3v as the basis for this project, mainly because a USB Host Shield is available for it.
But I cannot find a suitable Module for charging the LiPo that automagically switches to powering the project when not plugged in without the need for multiple USB sockets on the one device.
I am still researching all the sensors I need, but my other concern is powering all of the peripherals on the various buses.
Is the Trinket pro a better choice?
