* Do we have the version of ChibiOS with this bug.
* @detail Set to TRUE if ChibiOS has this bug.
* @note Fixed in ChibiOS 2.4.4stable and 2.5.2unstable (and the repository from 18th Feb 2013)
* @note This bug prevents us re-calling adcStartConversionI() from with the ISR even though
* it is clearly designed to handle it. For some reason (on this micro) the high speed timer
* is not affected only the single sample low speed timer. In that situation we wait until
* we get back to thread land. This is terrible for the accuracy of the high speed timer
* but what can we do (other than fix the bug).
* @note For the AT91SAM7 ADC driver, it post-dates the finding of the bug so we safely
* say that the bug doesn't exist for this driver.

*
* @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.
