/**
* @file include/gadc/gadc.h
* @brief GADC - Periodic ADC subsystem header file.
*
* @addtogroup GADC
*
* @details The reason why ChibiOS/GFX has it's own ADC abstraction is because
* the Chibi-OS drivers are very CPU specific and do not
* provide a way across all hardware platforms to create periodic
* ADC conversions. There are also issues with devices with different
* characteristics or periodic requirements on the same ADC
* device (but different channels). This layer attempts to solve these
* problems to provide a architecture neutral API. It also provides extra
* features such as multi-buffer chaining for high speed ADC sources.
* It provides one high speed virtual ADC device (eg a microphone) and
* numerous low speed (less than 100Hz) virtual ADC devices (eg dials,
* temperature sensors etc). The high speed device has timer based polling
* to ensure exact conversion periods and a buffer management system.
* The low speed devices are assumed to be non-critical timing devices
* and do not have any buffer management.
* Note that while only one high speed device has been provided it can
* be used to read multiple physical ADC channels on the one physical
* ADC device.
* All callback routines are thread based unlike the Chibi-OS interrupt based
* routines.
