Hi I want to build a ulisp badge. I’ve searched the forums but couldn’t find anything that would help me do this. I want to add my own code to support the keypad(4x4) which is to be used as a keyboard and I would like to know if there is an option to make ulisp display what is written on the keyboard on the display instead of on the serial port
I assume you’ve seen the original article about the Lisp Badge?
To make uLisp use a built-in display and keyboard in place of (or as well as) the Serial port you need to add code to support the keyboard and display. Have a look at the Lisp Badge firmware to see how to do that:
Feel free to ask any questions about that.
