Add basic CMSIS core headers (#384) 
Adds a new cmsis_core INTERFACE library, which provides the basic CMSIS macros/definitions, and RP2040.h and system_RP2040.h
By default the isr_ methods in the vector table are renamed to their CMSIS versions, but this can be overridden by defining PICO_CMSIS_RENAME_EXCEPTIONS=0

allow setting exception handler to the same value, as this might happen if exceptions are set dynamically on both cores, but VTOR is the same... this should indeed cause an error if the values differ, but not otherwise (#385) 2021-05-11 10:34:41 -05:00

Rework ordering of cmake, so that libraries in subdirectories can add to internal lists as PICO_SDK_POST_LIST_FILES, PICO_CONFIG_HEADER_FILES etc. (#382) 
Move generation of config header later, so it gets to include all values for PICO_CONFIG_HEADER_FILES

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.

a362925eda Clean up various C source and headers to appease -Wstrict-prototypes 
In C, func() is a function taking an unspecified number of arguments,
vs func(void) a function taking no arguments. In C++ both forms indicate
"no arguments."

Update these headers to use the (void) form, which is correct in both
languages and avoids complaints when -Wstrict-prototypes is specified.
