File:LinkSprite pcDuino2 with ITeadstudio 2.4 TFT LCD Touch shield.jpg

The ITeadstudio 2.4 TFT LCD Touch shield makes use of the Arduino pins A5/A4/A3 (as RS/WR/CS pins for LCD). These pins are primarily used for analog input on Arduino, but can be also configured as general purpose digital pins too. Unfortunately pcDuino can only use them for analog input (YN_TP, YP_TP, XN_TP). It means that this particular shield can't be really attached as a shield to LinkSprite pcDuino2 and successfully used this way.

Resorting to jumper wires and using other pins naturally works, but is not very pretty.
