I'm glad to be here in this forum, but totally new to Arduino (but used to Atmel microcontrollers) and I'm not sure if this is the right forum for my question...
Im looking for an USB IO-Board that can be run from the PC using my own programs (Windows/Linux). The Pins needed are IO, PWM, SPI and ADC, so the Arduino Mega 2560 seems to fit quite fine here. My question is, could the Arduino Mega 2560 be used as simple (stupid) IO-Board working realtime with my software from the connected PC or could it only be programmed itself?
Maybe someone has done a project like this. Or maybe you could suggest some different hardware that I could use.
Many thanks for your help!!
