See the ``sender-chip.pl`` test program. -The timing via the sysfs interface is awful. - -It looks like we can drive the pins (not the XIO ones) via -memory-mapped registers: the sunxi-tools ``pio.c`` has most of the -code needed. - -We could write a C program to just send the signal train. Look at -``clock.c`` for a way to handle fast / real-time scheduling and -delays. +If we keep the ``*/value`` file open, we get good enough timing. The +``sender-chip.c`` program works. |
