Hi hackers, I originally submitted this question on 'questions' but didn't receive much response. I am planning on putting a small 16x2 line LCD panel (crystalfontz 633) on a FreeBSD system, and writing a small application to control and display various things via the LCD and buttons. This is fine. My question is, I would really like to be able to display various things during startup, shutdown, and once shutdown is complete to the LCD. I assume I would have to modify the kernel for this. I done lots of C programming, and hardware interface programming in C and assembler, but never any UNIX kernel programming. First of all, is this doable? Also, would it be easier (from the kernel programming perspective) to do this via USB or Serial? Thanks for any and all advice. Tim (Please CC: me as I am not subscribed to this list - thanks)
