Moves to just released GCC 14.3
Moves to full-fat printf/scanf because Newlib no longer supports all the
calls libstdc++ requires with the older, smaller, nano-formatted-io option.
Moves to latest SDK develop branch with important float acceleration fixes
for the RP2350, among other updates.
Moves to latest pioasm, picotool develop branches
* SDK was refactored, update the includes
* Rebuild PicoSDK and BearSSL libs
* Update certs in BSSL validation example
* Don't spell check the certs!
* Updated tools with full fat++ newlib printf/scanf
Newlib has a stack protector fail handler which write(2)s a
message to STDERR which doesn't work here. Override with a
call to panic().
Tell GCC to protect all functions for stack protection instead of
ones that it heuristically decides need protection. Slower but
safer, and only when stack protection is enabled.
* Add PIO.h header verification to CI
Ensure all PIO .pio.h headers match the .pio sources in the tree
* Install all tools for Style check
* Clean up mismatched PIO headers
No functional changes, but the PDM pdm.pio file did not init a data pin
while the pdm.pio.h (the one actually used in the core) did. Correct to
match.
* No need for submodules in the style check
* Convert to SDK RP2350A/B determination
Fixes#2878
The SDK uses `defined(PICO_RP2350) && !PICO_RP2350A` to indicate an RP2350B
chip, not the define PICO_RP2350B.
Match the SDK's usage by converting from `defined(PICO_RP2350B)` to
`defined(PICO_RP2350) && !PICO_RP2350A` and update the chip variants
accordingly.
* Need to explicitly override PICO_RP2350A for all
The *SDK*'s board definition file hardcodes a PICO_RP2350A value for
all boards, but we use the same board file for both A and B variants.
Override the SDK board definition in the variant definition file.
* Generic RP2350 needs 2-stage PICO_RP2350A setting
Also ensure SDK board definition included before pins_arduino.h for
clearing up redefinition errors.
* Factor out undef PICO_RP2350A
* Update Arduino.h
Boards with selectable flash sizes only had a 1MB FS as the smallest
option on 2MB boards. For the normal Pico @ 2MB, though, we supported
filesystems down to 64KB. Add those same options to the 2MB SKUs
of configurable boards.
Windows Python doesn't seem to kill the worker Thread properly when the IDE
is exited, leading to a) multiple Python3 instances on a PC after many uses
and b) errors updating the core when it tries to re-install Python3 while
still having the older version's EXE loaded and in use.
When an exception happens on the input() call under Windows, it seems like it
can still leave a thread running. Add one more flag, caught in a global
exception handler.
Works around https://github.com/arduino/arduino-cli/issues/2867
Supercedes #2815
Move to pico-sdk official develop branch which includes a necessary
IRQ header fix.
200MHz is now default for the Pico, but 133 is still available from
the menus.
* Don't set SDFAT_FILE_TYPE, default is OK
Fixes#2772
No need to set SDFAT_FILE_TYPE=3 as that is the defaulr value with upstream
SdFat. Remove it from platform.txt and platform.io build.
* Codespell got all techy
* Replace ESP8266SdFat w/SdFat 2.3.0, add SDIO and ExFAT support
Remove ESP8266SdFat fork and replaces with upstream SdFat to simplify
maintenance.
This 2.3.0 version adds SDIO support and enables exFAT support.
Also upgraded FAT filename support to 256 chars, identical to LittleFS.
* Add SDIO support to SD and SDFS, documentation, and examples
* Update SD examples to all support SPI0, SPI1, or SDIO
* Remove Pico-SDK C++ exception-override new/delete
We support exceptions on and off, but the cxx_options file in the
SDK implemented a single override to new/delete.
Remove it so we will use GCC's build-in operator new/delete
which will be correct for either option (2 different libstdc++
versions are shipped as part of the toolchain).
* Remove duplicated SDK files
The SDK will link in the same compilation unit in the LWIP builds.
Remove them to shrink the repo size by ~28MB.
Pico-SDK changed the output extension of their compilation from "x.c.obj"
to "x.c.o" meaning the removed Newlib and STDIO SDK wrappers were still
being linked in certain situations. Update make-libpico Cmakefile to
remove the new names.
Fixes debug `printf` output.
Calculating the DMA clock divider for PWMAudio can take a very long time
because there are 65K floating point divisions required. But most audio
will be one of a dozen sample rates, so it is possible to precalculate
the rates on the host and use a small lookup table to avoid any math at
all. Removes occasional scratching in PWMAudio when the BackgroundAudio
library changes sample rates.
* my attempt at adding plasma_2040 support.. cant seem to get it working to test yet though?
* Tracked+replaced files, this now works it seems!
* correct serial count
* Update pins_arduino.h
* Rudimentary Pimoroni Plasma2350 support.
* include correct files + changes needed for proper support.
also!! fixes pin definitions for the i2c on Pimoroni Plasma 2350 (tested, working) and (presumably, untested) on the Plasma RP2040 too by swapping the i2c numbers. i2c now works!!
* use correct USB PID for Plasma 2350
Semihosting is handy for debugging, so allow the core to use `SerialSemi` as the
::printf port. Add menu item to the IDE to allow selection.
Add RISC-V implementation of semihost call
* added logic so that the build.mcu value is written to a board defintion in boards.txt. This is needed for Arduino libs that use precompiled/archive libs
* move the setting for the build.mcu as recommended - to manage the different archs available on the rp2340
Adds a menu item to enable onboard profiling. This requires significant
RAM and really only makes sense on devices with PSRAM to store the state.
When the menu item is selected, allocates RAM and tracks function calls and
periodically samples the PC to generate a histogram of application usage.
The onboard gmon.out file can be written over Semihosting or
some other way to transfer to a PC for analysis.
Adds a profiling example with command lines.
Using pico-sdk develop branch, add in support for CYW43-based
WiFi/BT/BLE boards on the RP2350 such as the
SparkFun Thing Plus RP2350 or the Pimoroni Pico Plus 2W.
Fixes#2608
Rolls in dynamic SPI divider #2600
* Support LED digitalWrite on RP2350+CYW
Also move "special GPIO" to 64 since the Pimoroni Pico 2W uses the
RP2350B with 48 GPIOs.
* Enable CYW43_PIN_WL_DYNAMIC in IDE and P.IO
Allows calling `cyw43_set_pins_wl(cyw43_pin_array);` to redefine the
CYW43 hookup in the variant initialization.
* Add SparkFun Thing Plus RP2350
* Add Thing Plus RP2350 PSRAM definition
* Remove radio from Thing Plus RP2350
Will need to add back once full radio support is added, see #2605
* Enable LWIP IGMP, MDNS internal server
* Enable MDNS lookup from LWIP DNS
* Add SimpleMDNS responder, small code and no malloc
* Ensure we copy out lwipopts in make-libpico
Adds a small wrapper around the LWIP-provided MDNS responder application.
Drop-in replacement in many basic cases for LEAmDNS.
For FreeRTOS it is important to not allocate memory on an LWIP callback.
LEAmDNS needs to do this to create response objects, leading to crashes.
Increase LWIP timers by bumping the LWIP_ARP number (as done before).
Replace ArduinoOTA LEAmDNS with SimpleMDNS and update a
HTTPUpdateServer example.
