The aim + is to fill the gap between the somewhat similar hwmon and input + subsystems. + Hwmon is directed at low sample rate sensors used to monitor and + control the system itself, like fan speed control or temperature + measurement. Input is, as its name suggests, focused on human interaction + input devices (keyboard, mouse, touchscreen). In some cases there is + considerable overlap between these and IIO. + + + Devices that fall into this category include: + + + analog to digital converters (ADCs) + + + accelerometers + + + capacitance to digital converters (CDCs) + + + digital to analog converters (DACs) + + + gyroscopes + + + inertial measurement units (IMUs) + + + color and light sensors + + + magnetometers + + + pressure sensors + + + proximity sensors + + + temperature sensors + + + Usually these sensors are connected via SPI or I2C.

At probe: + + call iio_device_alloc, which allocates memory + for an IIO device. + + initialize IIO device fields with driver specific information + (e.g. device name, device channels). + + call iio_device_register, this registers the + device with the IIO core. After this call the device is ready to accept + requests from user space applications. + + + At remove, we free the resources allocated in + probe in reverse order: + + iio_device_unregister, unregister the device + from the IIO core. + + iio_device_free, free the memory allocated + for the IIO device. + + + + IIO device sysfs interface + + Attributes are sysfs files used to expose chip info and also allowing + applications to set various configuration parameters.

An + IIO device can have one or multiple channels. For example: + + + a thermometer sensor has one channel representing the + temperature measurement. + + + a light sensor with two channels indicating the measurements in + the visible and infrared spectrum. + + + an accelerometer can have up to 3 channels representing + acceleration on X, Y and Z axes. + + + An IIO channel is described by the struct iio_chan_spec + .

Modifiers are specified using + .channel2 field of the same + iio_chan_spec structure and are used to indicate a + physically unique characteristic of the channel such as its direction + or spectral response. For example, a light sensor can have two channels, + one for infrared light and one for both infrared and visible light. + + set .indexed field of + iio_chan_spec to 1.

A + trigger may initiate data capture for a number of sensors and + also it may be completely unrelated to the sensor itself. + + + IIO trigger sysfs interface + There are two locations in sysfs related to triggers: + + /sys/bus/iio/devices/triggerY, + this file is created once an IIO trigger is registered with + the IIO core and corresponds to trigger with index Y.

Media currently in use are +fiber optics, unshielded twisted pair cables (UTP) and coax cables. MOST +also supports various speed grades up to 150 Mbps. +For more information on MOST, visit the MOST Cooperation website: +www.mostcooperation.com. + +Cars continue to evolve into sophisticated consumer electronics platforms, +increasing the demand for reliable and simple solutions to support audio, +video and data communications. MOST can be used to connect multiple +consumer devices via optical or electrical physical layers directly to one +another or in a network configuration. As a synchronous network, MOST +provides excellent Quality of Service and seamless connectivity for +audio/video streaming. Therefore, the driver perfectly fits to the mission +of Automotive Grade Linux to create open source software solutions for +automotive applications. + +The driver consists basically of three layers. The hardware layer, the +core layer and the application layer. The core layer consists of the core +module only. This module handles the communication flow through all three +layers, the configuration of the driver, the configuration interface +representation in sysfs, and the buffer management. +For each of the other two layers a selection of modules is provided. These +modules can arbitrarily be combined to meet the needs of the desired +system architecture. A module of the hardware layer is referred to as an +HDM (hardware dependent module). Each module of this layer handles exactly +one of the peripheral interfaces of a network interface controller (e.g. +USB, MediaLB, I2C). A module of the application layer is referred to as an +AIM (application interfacing module). The modules of this layer give access +to MOST via one the following ways: character devices, ALSA, Networking or +V4L2. + +To physically access MOST, an Intelligent Network Interface Controller +(INIC) is needed. For more information on available controllers visit: +www.microchip.com + + + + Section 1.1 Hardware Layer + +The hardware layer contains so called hardware dependent modules (HDM). For each +peripheral interface the hardware supports the driver has a suitable module +that handles the interface. + +The HDMs encapsulate the peripheral interface specific knowledge of the driver +and provides an easy way of extending the number of supported interfaces. +Currently the following HDMs are available: + + 1) MediaLB (DIM2) + Host wants to communicate with hardware via MediaLB. + + 2) I2C + Host wants to communicate with the hardware via I2C. + + 3) USB + Host wants to communicate with the hardware via USB. + + + Section 1.2 Core Layer + +The core layer contains the mostcore module only, which processes the driver +configuration via sysfs, buffer management and data forwarding. + + + + Section 1.2 Application Layer + +The application layer contains so called application interfacing modules (AIM). +Depending on how the driver should interface to the application, one or more +suitable modules can be selected. + +The AIMs encapsulate the application interface specific knowledge of the driver +and provides access to user space or other kernel subsystems. +Currently the following AIMs are available + + 1) Character Device + Applications can access the driver by means of character devices. + + 2) Networking + Standard networking applications (e.g. iperf) can by used to access + the driver via the networking subsystem. + + 3) Video4Linux (v4l2) + Standard video applications (e.g. VLC) can by used to access the + driver via the V4L subsystem. + + 4) Advanced Linux Sound Architecture (ALSA) + Standard sound applications (e.g. aplay, arecord, audacity) can by + used to access the driver via the ALSA subsystem. + + + + Section 2 Configuration + +See ABI/sysfs-class-most.txt + + + + Section 3 USB Padding + +When transceiving synchronous or isochronous data, the number of packets per USB +transaction and the sub-buffer size need to be configured. These values +are needed for the driver to process buffer padding, as expected by hardware, +which is for performance optimization purposes of the USB transmission. + +When transmitting synchronous data the allocated channel width needs to be +written to 'set_subbuffer_size'. Additionally, the number of MOST frames that +should travel to the host within one USB transaction need to be written to +'packets_per_xact'. + +Internally the synchronous threshold is calculated as follows: + + frame_size = set_subbuffer_size * packets_per_xact + +In case 'packets_per_xact' is set to 0xFF the maximum number of packets, +allocated within one MOST frame, is calculated that fit into _one_ 512 byte +USB full packet. + + frame_size = floor(MTU_USB / bandwidth_sync) * bandwidth_sync + +This frame_size is the number of synchronous data within an USB transaction, +which renders MTU_USB - frame_size bytes for padding. + +When transmitting isochronous AVP data the desired packet size needs to be +written to 'set_subbuffer_size' and hardware will always expect two isochronous +packets within one USB transaction. This renders + + MTU_USB - (2 * set_subbuffer_size) + +bytes for padding. + +Note that at least 2 times set_subbuffer_size bytes for isochronous data or +set_subbuffer_size times packts_per_xact bytes for synchronous data need to be +put in the transmission buffer and passed to the driver. + +Since HDMs are allowed to change a chosen configuration to best fit its +constraints, it is recommended to always double check the configuration and read +back the previously written files. + + + + Section 4 Routing Channels + +To connect a channel that has been configured as outlined above to an AIM and +make it accessible to user space applications, the attribute file 'add_link' is +used. To actually bind a channel to the AIM a string needs to be written to the +file that complies with the following syntax: + + "most_device:channel_name:link_name[.param]" + +The example above links the channel "channel_name" of the device "most_device" +to the AIM.
