Can you post the C code to send keystrokes via usb using the teensy? Its been so many years since I programmed in C I'm feeling a bit overwhelmed by the all the code Im digging through to figure this out. An example code would be of such great help!
It seems to me that we need is a macro recorder that can record key strokes AND mouse actions then play them back (switching between keyboard and mouse), yet regulate the playback speed on things like pasting in a payload. Im only now starting to learn about HID device. Its it possible to switch between keyboard and mouse? Do the keyboards with mouse controls on them act as two separate Human Interface Devices or is there a mode that does both on the same cable?
