Pin-Out Description
5. Pin-Out Description
Most signals on Embedded Master Module are multiplexed to offer more than one function
for every pin. It is up to the developer to select which one of the functions to use. GHI
drivers and .NET Micro Framework does some checking to make sure the user is not
trying to use two functions on the same pin. The developer should still understand what
functions are multiplexed so there is no conflict. For example, analog channel 3 (ADC3)
and the analog output (AOUT) are on the same pin. Either function can be used but not
both of them simultaneously.
Digital I/O pins are named Exx, where xx is an assigned number. GPIO pins for the TFT
version are named ETxx.
Make sure your design is made to accept the TFT / Non-TFT version of the modules. The
pads are compatible.
