I'm working on a project with an Arduino where I need to use the Eigen library, so I'm using EigenArduino . However, this library requires a standard library, which is not available on Arduino, by default ; so, as Eigen's maintainer recommends, I tried using stlport-avr .
The problem is that by default this library does not provide access to iostream , so I can not use cout to print debug information . I've tried using Serial , but it does not work - Eigen was not meant to be used with this.
Is there any way to use cout on an Arduino. Or at least a way to use Serial to print debug information?
