Hey all, first time electronics project here.
I decided to learn a bit about electronics I would make a drink-mixing bot. I've got all the code fleshed out for dispensing drinks, and thats all fine, but where I'm running into trouble is that I want to use both the Wave Shield (http://www.ladyada.net/make/waveshield/) and the 1.8" TFT LCD w/ MicroSD (https://www.adafruit.com/products/358 ). It seems they both require pins 11-13 for use with their own SD cards. Normally I know this would mean you cant use them both at the same time. However, if I stack these shields, and make sure not to use them concurrently, will everything work?
For example, I would draw a bitmap onto the LCD, the user selects it through a button, and once that selection has been made, the wave shield plays a clip. Would the two SD cards conflict?
If they do, is there any way I could do this? Could I make both shields share the same SD card? If so, how? I've looked at SDFat libraries and unless I'm missing something it doesn't seem to mention it...
I'm using an arduino mega2560.
