d6e1b2efe5 Add skeleton of allocation code for kmalloc and kfree. Currently allocates a dummy storage area. 2012-11-18 14:36:05 +00:00
Robin Mallinson
4b87d814df Add crude 'written_data' array so dev_read simply echos verbatim what was written to dev_write without probing the actual DMA control block data. This gives no clue as to whether the DMA control bloack has been programmed but does mean that Richard's control code - which has a special case for delay=0 - does not require changing. Next steps are to have an array per-process. 2012-11-18 14:09:45 +00:00

94c2aab61b Revert to original code re: setting delay, so we again have a delay of 1 
for a pulse of zero.  Will frig the display issues by using an array that
stores written cnt rather than deriving it from actual register data.

b4463ce836 Update readme to show output format of /dev/servoblaster. 
Note that they show a value of 1 rather than the expected 0 initially.

8002904e4e Enable dev_read code, plus fix a couple of syntax errors (the code hadn't been compiled). 
It appears to work at a cursory level:

pi@raspberrypi ~/src/PiBits/ServoBlaster $ sudo insmod ./servoblaster.ko
pi@raspberrypi ~/src/PiBits/ServoBlaster $ ls -l /dev/servoblaster
crw-rw-rw- 1 root root 251, 0 Nov 11 19:22 /dev/servoblaster
pi@raspberrypi ~/src/PiBits/ServoBlaster $ cat /dev/servoblaster

for each of the 8 PWMs via /dev/servoblaster.
