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
When a link comes up, we were only sending a DHCP request if the existing
netif's ipaddress was 0. When a DHCP lease is acquired at first that IP
is changed to the given address, and if we do another ::begin we wouldn't
dhcp_start to send a new request and use the old one (until its lease
expired).
In the case of network changing (i.e. WiFiMulti on different nets or
moving an Ethernet cable to another router) that old address would not
be valid.
Track if an IP address has been manually set and use that to determine
if DHCP needs to be re-requested instead of looking at the old netif's
ipaddress.
Fixes#2974
Fixes#2935
The PICO_2350A patch flipped the logic of the ADCInput bitmask calcs
causing the 2040 and 2350A to use bitmasks for the 2350B (i.e. wrong
GPIOs) and vice versa.
* 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
* Initial commit.
* Works with AK4619 in TDM128 I2S compatibility mode set to rising BCLK.
* Works with I2S compat mode with BCLK mode set to 0 on AK4619.
My application is designed to generate HSTX data on core0 in interrupts,
but also uses hardware SPI for SD card access.
It turns out that the amount of time spent in maskInterrupts/
unmaskInterrupts, even with an empty _usingIRQs, is too long.
Add a quick check and avoid touching the interrupt disable flag if
there's not actually any GPIO interrupt to (un)mask.
* Move to Arduino API 10501
Track upstream Arduino API headers
* IPAddress V4/V6 compatiblity restored
* Fix WiFiUDP includes
* String differences in example
* HardwareSerial using exported
* Add PIO-based SoftwareSPI enabling SPI on any pins
The Raspberry Pi team has a working PIO-based SPI interface. Wrap it
to work like a hardware SPI interface, allowing SPI on any pin
combination.
Tested reading and writing an SD card using unmodified SD library.
* Add W5500 example
Good for testing, shows non-contiguous pin outs.
* Added buffer read to `AudioBufferManager` and `I2S`. Example and documentation included.
* Update type of words to unsigned in example.
* Improve buffered loopback example.
* Remove const from read buffer.
* 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
When multiple inputs were active, the frequency was being scaled two
times resulting in incorrect sampling speed. Correct to only scale
the calculation and not the stored value (which is used in `begin`).
Fixes#2754
The memcpy-version of the ABM::write updated the destination and count
but neglected to move the source forward. If a block write crossed a
frame boundary then the 2nd frame would repeat the data from the first
half of the buffer.
Fix by incrementing the source pointer by the same amount as was written.
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.
Optimize AudioRequestBuffer writing when large blocks are available (i.e.
I2S writes of full MP3 or AAC frames in BackgroundAudio). Update I2S to use
the new call. Reduces 1152 calls to arb::write() to a single call/return
and optimized memcpy in that case.
The audio output objects all have the same general necessary configuration
calls. Abstract them out to a generic AudioOutputBase interface class that
they will inherit from. Simplifies letting applications use different
output channels.
Should be backwards compatible with existing code.
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
* Add MDNS.addServiceTxt() to SimpleMDNS
Fixes#2678
A simple mapping allows for basic service text addition even when using
SimpleMDNS and ArduinoOTA.
* Protection against duplicate services addition
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.
Enable ARM-only semihosting mode. This mode allows applications on the
Pico to write to the OpenOCD console and read and write files on the
host system (i.e. debugging dump information, etc.)
It is not very fast because of the way it uses breakpoints on the Pico
to communicate, but it is useful in cases when you want to get a single
file off of the Pico while debugging.
Note that this **requires** a connected OpenOCD and GDB or else the
semihosting will cause a system panic.
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.
