tools:iio:iio_generic_buffer: fix trigger-less mode

2016-08-29T17:06:21Z

Passing the trigger-less mode option on the command line causes iio_generic_buffer to fail searching for an IIO trigger. Fix this by skipping trigger initialization if trigger-less mode is requested. Technically it actually fixes: 7c7e9dad70 where the bug was introduced but as the window to the patch below that changes the context was very small let's mark it with that.

tools: iio: iio_generic_buffer: initialize channel array pointer

2016-08-15T16:05:30Z

Uninitialized channel pointer causes segmentation fault when we call free(channel) during cleanup() with no channels initialized. This happens when you exit early for usage errors. Initialize the pointer to NULL when it is declared. Signed-off-by: Alison Schofield Cc: Daniel Baluta Tested-by: Gregor Boirie Signed-off-by: Jonathan Cameron

iio: iio_generic_buffer: Cleanup when receiving signals

2016-05-29T19:37:23Z

This will clean (disable buffer/trigger/channels) when doing something like a CTRL-C. Otherwise restarting generic_buffer requires a manual echo 0 > buffer/enable This also cleanup up all the code freeing string buffers at the end of main. We initialize all pointers to NULL so that cleanup can all be done under a single error label. Signed-off-by: Crestez Dan Leonard Signed-off-by: Jonathan Cameron

iio: tools: generic_buffer: auto-enable channels

2016-04-19T18:58:13Z

If no channels are enabled when we run generic_buffer on a device, add a command-line option to just enable all of them, run the sampling and disable them all again afterwards. This is extremely useful when I'm low-level testing my sensors with interrupts and triggers, sample session: root@Ux500:/ lsiio Device 000: lsm303dlh_accel Device 001: lis331dl_accel Device 002: l3g4200d Device 003: lsm303dlh_magn Device 004: lps001wp Trigger 000: lsm303dlh_accel-trigger Trigger 001: lis331dl_accel-trigger Trigger 002: l3g4200d-trigger root@Ux500:/ generic_buffer -a -c 10 -n l3g4200d iio device number being used is 2 iio trigger number being used is 2 No channels are enabled, enabling all channels Enabling: in_anglvel_x_en Enabling: in_anglvel_y_en Enabling: in_anglvel_z_en Enabling: in_timestamp_en /sys/bus/iio/devices/iio:device2 l3g4200d-trigger -3.593664 -0.713133 4.870143 946684863662292480 3.225546 0.867357 -4.945878 946684863671875000 -0.676413 0.127296 0.106641 946684863681488037 -0.661113 0.110160 0.128826 946684863690673828 -0.664173 0.113067 0.123471 946684863700683593 -0.664938 0.109395 0.124848 946684863710144042 -0.664173 0.110619 0.130203 946684863719512939 -0.666162 0.111231 0.132651 946684863729125976 -0.668610 0.111690 0.130662 946684863738739013 -0.660501 0.110466 0.131733 946684863748565673 Disabling: in_anglvel_x_en Disabling: in_anglvel_y_en Disabling: in_anglvel_z_en Disabling: in_timestamp_en Pure awesomeness.
