Posix open() calls to /dev/adc# were hanging often due to the ready loop check at the end of adc_enable() never returning. According to ES0565 document, at least 4 ADC clock cycles must pass between the time we waited for calibration to end and before we can set ADEN. This will depend on what clock is set for ADC. So to ensure enough time passes, we are adding a short delay (so that even a slow clock will work). Also, we are clearing the ADRDY flag before hand to ensure we are detecting a fresh event. The delay to wait for the voltage regulator is also increased to account for extra time required in non-ideal conditions. Signed-off-by: Liam Howatt <liamhowatt@geotab.com> |

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
