First of all, I am using the seeedstudio tft shield along with an arduino uno and the seeedstudio GPRS shield v2.1.
With that out of the way I am creating a personal cellphone for everyday usage
I am almost complete with this project, having set up one way texting and calling with ease.
There is, of course, a interactive GUI to go with this.
However, when trying to set up receiving texts, I ran into several problems.
Though it seems as if my problems were solved by finding a library for the GPRS shield (can't find the link right now)the examples worked fine, but when i put them into my project the TFT does not register touches to my TEXT and CALL buttons
Namely, when a text is received it is supposed to pull up a menu showing the message, sender, and the time
below are some portion of my code, namely variable definitions and the example codes implication into my project.
Please ask if any other information is required, as I have been working in this pinch for a while, and am a newbie to these forms (I found that i had created an account sometime in the past)
thanks in advance
