iio: tools: generic_buffer: auto-enable channels

2016-04-19T18:58:13+00:00

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. If some channels have been enabled through scripts or manual interaction, nothing happens.

iio: tools: make generic_buffer look for "-trigger"

2016-04-03T09:27:49+00:00

All the ST Sensors use the old "-trigger" rather than the standard "-devN" new standard suffix for triggers. Now much to do about it since it is ABI, but make the testing tools recognize it too. Signed-off-by: Linus Walleij Signed-off-by: Jonathan Cameron

iio: generic_buffer: be helpful about enabling channels

2015-08-16T09:51:26+00:00

Currently if generic_buffer is invoked without first enabling any channels in scan_elements/*_en, it will fail unable to enable the buffer because bytes_per_datum inside the kernel will be zero if no channels are available. It is implied that the user of the program should enable channels manually or with a script before executing generic_buffer. Be more helpful by stopping execution if no enabled channels can be found, and print a helptext that will tell you what is wrong and what needs to be done.

iio: event_monitor: report unsupported events

2015-08-16T09:51:25+00:00

This makes the event monitor bail out with a helpful error message if a device does not support events, as a related fix to iio core now makes it return -ENODEV properly. Signed-off-by: Linus Walleij Acked-by: Hartmut Knaack Signed-off-by: Jonathan Cameron

iio: lsiio: fix error code handling error

2015-08-12T18:26:22+00:00

commit acf50b3586f8d8a7530b905e111dda41876d38f4 "tools:iio:lsiio: add error handling" introduced error handling of errors returned from read_sysfs_string(), but with a simple if (retval), missing the fact that these functions return a positive value if the read was successful. As a result lsiio regresses and does not show any devices on my filesystem. Fix this by checking for only negative error codes.

tools: iio: Set caller's ci_array pointer to NULL after free

2015-08-08T18:51:39+00:00

On error, caller's ci_array is freed and set to NULL to avoid potential double free if some other user of this code is not sufficiently careful. Counter is reset to zero for consistency. Signed-off-by: Joo Aun Saw Signed-off-by: Jonathan Cameron
