Earle F. Philhower, III Brings the Arduino Pico Core to V4.0.1, Provides RP2350 and Pico 2 Assist

Developer Earle F. Philhower, III has launched model 4.0.1 of his Arduino Core for the Raspberry Pi Pico household — bringing with it help for the newly-launched Raspberry Pi Pico 2 and its RP2350 chip.

“It is a main launch with help for the Raspberry Pi Pico 2 (RP2350) utilizing [the] new SDK [Software Development Kit] 2.0.0,” Philhower explains of the newest launch. “New RP2350-based boards from iLabs, Solder Celebration, and SparkFun are supported along with the Pico 2. The complete 512k of RAM and as much as 8MB of PSRAM [Pseudo-Static RAM] can be found for functions to make use of.”

Philhower’s Raspberry Pi Pico Arduino Core, designed so as to add the power to program the Raspberry Pi Pico and different RP2040-based growth boards utilizing the Arduino IDE and with the acquainted Wiring library, was launched again in March 2021 — beating official help to the punch. Providing a substitute for programming the microcontroller in straight C/C++ or MicroPython, the Core has confirmed well-liked — and is now prolonged to incorporate the Raspberry Pi Pico 2 and its uncommon dual-architecture RP2350 chip, albeit solely in Arm mode for now.

“Particular due to arturo182 for a terrific code overview that helped get a working RP2350 construct even earlier than I had any chips in hand,” Philhower says of those that made the discharge doable, “and to Pontus [Oldberg], [Kevin Santo Cappuccio], and [Kird D. Benell] for kindly supplying chips and boards earlier than I may even get them organized right here within the US.”

The newest core, model 4.0.0, consists of help for the 2 Arm Cortex-M33 cores of the Raspberry Pi RP2350 — however not but the free and open supply Hazard3 RISC-V cores that sit alongside them on the chip, usable both on their very own or with the Arm cores in a 1/1 cut up. “Every part that labored on the RP2040 ought to work on the RP2350,” Philhower says, “apart from FreeRTOS ([which] requires use of a personal [Raspberry Pi] fork of the upstream we use) and OTA [Over The Air] ([which] requires me to grasp the brand new bootup sequence higher. SPI, I2C, LittleFS, EEPROM, PWMAudio, LWIP-based networking, multicore, SDK USB and TinyUSB, and extra have been verified.”

Formally confirmed as supported within the new launch are the Raspberry Pi Pico 2 and boards from three third-party distributors: the Invector Labs Challenger RP2350 BConnect and Invector Labs Challenger RP2350 WiFi/BLE; the SparkFun ProMicro RP2350; and the Solder Celebration RP2350 Stamp and Solder Celebration RP2350 Stamp XL. The brand new launch additionally brings help for the WIZnet W6100 Ethernet controller, forward of the corporate’s launch of Ethernet-equipped Raspberry Pi Pico 2-style growth boards.
