Here's a short program to display the battery voltage. The get_battery_mv() interface might be useful in the kernel itself. Would it be appropriate for the kernel to turn on the low battery indicator as well? The A/D converter that the RCX uses to (...) (25 years ago, 12-Jan-00, to lugnet.robotics.rcx.legos)

(...) Actually I won't, since I just read memcpy.c and I see it's an __asm__ macro. I don't know if that's a valid __asm__ or not. In this case, if it's causing legOS pain, memcpy.c should just be replaced by memcpy.s with the correct assembly (...) (25 years ago, 11-Jan-00, to lugnet.robotics.rcx.legos)
