* @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.

* @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.

|

* and 'countPerEvent' parameters describe the number of conversions not the

* number of samples.
|

* As an example, if physdev turns on 2 devices then the buffer contains
|

* alternate device samples and the buffer must contain 2 * bufcount samples.
|

|
||||
* @note The buffer is circular. When the end of the buffer is reached it will start
|
||||
* putting data into the beginning of the buffer again.
|
||||
* @note The event listener must process the event (and the data in it) before the
|
||||
* next event occurs. If not, the following event will be lost.
|
||||
* @note If bufcount is evenly divisable by countPerEvent, then every event will return
|
||||
* countPerEvent conversions. If bufcount is not evenly divisable, it will return
|
||||
* a block of samples containing less than countPerEvent samples when it reaches the
|
||||
* end of the buffer.
|
||||
* @note While the high speed ADC is running, low speed conversions can only occur at
|
||||
* the frequency of the high speed events. Thus if high speed events are
|
||||
* being created at 50Hz (eg countPerEvent = 100, frequency = 5kHz) then the maximum
