Release 4.4.2 - Bug fixes and SDIO support
Overview
Multiple minor bug fixes across many subsystems. Adds SDIO (4-bit high speed) SD card support and moves to untouched SdFat upstream library. Speeds of up to 15MB/s with this mode have been shown, well above 1-bit SPI mode (but it does require a new physical adapter with all 4 DAT0...DAT3 pins). ExFAT support is now enabled as well, allowing for very large card access.
SD/SDFS
- Replace ESP8266SdFat w/SdFat 2.3.0, SDIO, ExFAT (#2764)
Library updates
New boards
- Add SparkFun IoT Node LoRaWAN (#2745)
Miscellaneous bug fixes
- Change duty cycle of PIO Tone to 50% (#2770)
- PIOProgram: Replace __pioHighGPIO with pio_get_gpio_base() (#2769)
- Fix ADCInput clocks for multiple inputs (#2755)
- Restore Bluetooth TLV on Pico2/RPiWiFi boards (#2753)
- Correct return from NTP.waitSet() (#2736)
- Remove unneeded SDK files from libpico/etc. (#2733)
- Remove SDK C++ new/delete, duplicated objects (#2760)
- A2DPSink: Remove stubs, fix volume and connect callbacks (#2757)
Release 4.4.1 - Minor refactoring and update
Overview
Minor quality-of-life release for audio output, especially PWMAudio. Precalculating values turns a 65K soft-FPU operation into a linear search of 12 entries in 99.9% of the cases.
I2S and PWMAudio and BluetoothAudio now share a common audio interface to simplify code like BackgroundAudio or ESP8266Audio.
Audio-related
- Allow setting PWMAudio frequency before begin (#2726)
- Properly wrap AudioBufferManager block writes (#2725)
- Add AudioOutputBase keyword
- Precalculate common PWMAudio dividers, avoid noise (#2714)
- Add real block write for AudioRequestBuffer (#2712)
- Overclock to 153.6 MHz (instead of 147.6 MHz) for I²S 48 kHz sample rate (#2708)
Infrastructure
Release 4.4.0 - Semihosting, GProf, and bug fixes
Overview
Major new feature is Semihosting which lets the Pico read and write files (and to the terminal) on the host while debugging. It's very handy for debugging and testing. The debug console can now be directed to the host through the IDE using this capability.
GNU profiling of running applications is also available, but is most useful on the RP2350 due to the RAM requirements.
Audio interfaces are unified under a C++ interface class for easier reuse in libraries or applications like BackgroundAudio. This should be backwards compatible with the prior individual classes.
Semihosting and Profiling
- Semihosting part of core, RISC-V support (#2685)
- Add semihosting support (SerialSemi and SemiFS) (#2670)
- Enable gprof onboard profiling (#2669)
- Add -O0 optimization mode to menus (#2667)
- GDB + mklittlefs can export on-device filesystems to the host (#2666)
New/Updated Boards
- Add Pimoroni Plasma 2350, fix Plasma 2040 I2C (#2698)
- Add MyMakers RP2040 board (#2692)
- Modify EVN Alpha board (#2690)
- Add build.mcu to board definitions (#2673)
WiFi and MDNS
Audio
Release 4.3.1 - Pico W and Pico 2W hotfixes

call on the Pico W and sets the proper Pico 2 W LED so things like blink.ino
will work properly. Increase to LWIP state to support simultaneous SimpleMDNS
and WiFiClient
s.

Release 4.0.3 - RP2350 updates and feature parity
Overview
Lots of RP2350 related goodness in the release, including higher performance and full FreeRTOS and OTA support with bug fixes for the RP2350B extra GPIO pins. A new toolchain build is included, moving to GCC 12.4 and Newlib 4.3.0 so be sure to run get.py
on your git
installations and update all submodules.
Toolchain
- GCC to 12.4, Newlib to 4.3.0, faster RP2350 libs (#2480)
This new toolchain speeds up many RP2350 operations by using -O2 optimization in Newlib. This speeds upmemcpy
over 8x(!) as well as other standard library routines, at the cost of ~10K of flash for additional code.
