| //simple one way terminal - characters from serial are directed to stdio | ||
| // Simple terminal program: | ||
| // Characters from the serial port are printed on the screen, and characters | ||
| // from the keyboard are sent to the serial port | ||
| // | ||
| // NOTE: Just like with a real terminal, characters from the keyboard don't get | ||
| // printed on the screen; the host computer (to which you connect the serial | ||
| // port) should take care of echoing the characters (or not, e.g. when you're | ||
| // typing a password). | ||
| // | ||
| // NOTE: this is a simple program that basically loops at full speed. It works | ||
| // fine but of course it's not very efficient with energy. It would be better | ||
| // to put the CPU to sleep and let the UART or the keyboard wake it up. This | ||
| // is left as an excercise for the reader :-) | ||
