Hello all and Happy Holidays
I have embarked on a project that has enticed me into coding for the first time in my life and now I am hooked. Please bare with me I am on my second week of coding, I am watching tutorials left and right learning as fast as I can.
So I have a Raspberry pi with 4x4 button pad(Trellis) that uses i2C. In python 2.7 I have pygame(This was the only wav player I could get to work in Python, if any one know of a better wav player , please let me know). Also in Python I have a GUI that will eventually load the wav files to the corresponding buttons(pads). So I have 3 different codes going on that I need to combine into one code.
Basically I want to press the GUI button and a combo box, combo box with a dropdown list of wavs, select wav and it will load into say pad 1, I now press pad one on the trellis and it will play the sound.
Here is the GUI
I also know this would be easier if I was just working on one button getting it to load and play just the one sound but the trellis is what throws me off, its a button matrix but in the code is referred to as trellis and well is just plain different from a simple button
Again thanx for any info

I am also still diving into the tutorials and maybe even find the answers myself but if anyone wants to help that is great, this an open source project that I will be uploading to github as soon as I figure out github.I also know this would be easier if I was just working on one button getting it to load and play just the one sound but the trellis is what throws me off, its a button matrix but in the code is referred to as trellis and well is just plain different from a simple button
Again thanx for any info
