Overview¶. void iio_triggered_buffer_cleanup (struct iio_dev * indio_dev) ¶ Free resources allocated by iio_triggered_buffer_setup() Parameters. This driver supports Analog Device’s IMUs on SPI bus. 3-rc3 there are around 184 IIO drivers IIO trigger ops¶. Original:. Buffers¶. The Linux Kernel 4. These tasks involved quite a few discussions between our engineering team and the IIO maintainers and reviewers. iio_validate_scan_mask_onehot() — Validates that exactly one channel is selected iio_buffer_get() — Grab a reference to the buffer Members. 10. 12. sensor_iio_pollfunc, the function that will be used as top half of poll function. The aim is to fill the gap between the somewhat similar hwmon and input subsystems. Multiple data channels can be read at once from /dev/iio:deviceX character device node, thus reducing the CPU load. It also handles clients (either in kernel or in User Space). If not specified, the IIO core uses the default iio_triggered_buffer_setup_ops. The Industrial I/O subsystem supports access to buffers through a file-based interface, with read() and write() access calls through the IIO device’s dev node.
