Keyboard Input in L4Re Pandaboard ARM
Hello L4 hackers I have a question about accessing standard I/O Is it possible to access keyboard using L4Re. If it's possible, can i access it using USB keyboard or do i need to access the std input from serial ? The idea of this question because i want to make a simple calculator to practice study the stdio of L4Re I am really sorry for the basic question And i am appreciating any helps and answer Thanks L4 Hackers -- *Regards,* *Erry Pradana Darajati | Student of Computer Engineering* *Politeknik Elektronika Negeri Surabaya / EEPIS, Indonesia*

Possible yes, but using the serial is much easier.

Use "REQUIRES_LIBS = libc_be_file_stdin" in your Makefile and getchar etc. should just work. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
