| | | I need to write a program that can send and receive messages, but there are times when the program is running, that I don't want to waste processor time watching for messages. Is it possible to switch LNP on and off, while a program is running? I (...) (21 years ago, 9-Oct-03, to lugnet.robotics.rcx.legos)

| | | | (...) Mark is correct: I made the following two changes which will cause the sensors to be polled at 1KHz: in systime.c; added "bset #0x5,@_AD_CSR:8"; extern void clock_handler(void); ... sys_nohigh: mov.w #0x5a06,r6 ; reset wd timer to 6 mov.w (...)
