add PICO_DIVIDER_DISABLE_INTERRUPTS flag which makes PICO_DIVIDER disable interrupts around division rather than using co-operative guards to protect nested use (i.e. within IRQ/exception). Use of this flag can simplify porting of RTOSes but with a different performance profile (#372) 2021-05-04 07:48:07 -05:00

Changed the parameter check to avoid tripping -Werror on spin locks (#307)
This prevents a comparison between a signed and an unsigned number which
will create a warning tripping -Werror.

Also added a check for the alignment of the spin lock structure

Add pico_get_unique_board_id_string API (#281)
* Add pico_get_unique_board_id_string API

Add a new API to pico_unique which will turn the unique ID into a
canonical text string.

Use this API to update the USB device serial number in stdio_usb.

Supercedes #280

* Clean up -Wconversion=error issues

* Address review comments, fix api typing

Use cleaner binary-to-hex conversion.  Update the length parameter to
use uint per the SDK standard .

Don't advertise REMOTE_WAKEUP for USB stdio as it is is not currently implemented. Longer term need to implement REMOTE_WAKUP properly in TinyUSB. Similar fix needed in MicroPython to fix MicroPython issue #6866. The symptom is that USB serial will stop working if there is a delay of > 2 seconds ish between messages. We have seen this issue on Linux laptops with USB autosuspend enabled. (#289) 2021-03-30 09:03:28 -05:00

e9a521a9b1 rtc_get_datetime: read the rtc registers just once each
In order for the returned value to accurately reflect a single moment in time,
ensure the registers are read just once and in the datasheet order.
Before this change, the RTC registers would each be read multiple times,
leading (infrequently) to the returned fields not all reflecting the same
moment in time.

The rp2040 datasheet has what I believe is an incorrect example (embedding
the source of this function); will the datasheet be updated if this function is
fixed?

This problem is only a speculative one; I did not actually observe it in the
wild.

383e88ea16 Add support for resetting RP2040 via the USB connection when using pico_stdio_usb
- setting baud rate to magic value (default=1200) will cause a reset to BOOTSEL mode
	- a VENDOR interface along side the CDC interface can be used to reset via refular flash boot, or into
	  BOOTSEL mode with control for the reset_usb_boot parameters for the latter
either method can be configured/enabled/disabled via #define
