We require help in optimizing and modification of an existing electronic board schematic with the following components
-microSD card reader
We need to develop the initial software for the microcontroller (MSP430). The boards must be able to sense the closing of the reed switch in order to activate audio/visual messages through the speaker/display. The user can also interact with the device through the two buttons. A first draft of the schematics has already been developed and components chosen, and needs testing and refinement. We've got the physical shell pretty much all designed, and we have a pretty complete flow chart describing the code we need done.
