arduino-pico VS pico-sdk

I managed to get the Arduino IDE to work great with my Pi Pico's using earlephilhower/arduino-pico and TinyUSB in the USB stack. I can code for MIDi and do all kinds of neat stuff... But...

I am trying to build a data logger. Currently my hardware is a Raspberry Pi Pico W, a SHT41 (https://www.adafruit.com/product/5776), and a small breadboard. Software is Arduino IDE, arduino-pico (https://github.com/earlephilhower/arduino-pico), and Adafruit_SHT4X library (https://github.com/adafruit/Adafruit_SHT4X).

The standard Pico w SDK has examples for Bluetooth classic, serial connection, mouse control, keyboard control etc... Everything you need can be found HERE

If you want more guidance, you could use the Arduino framework https://github.com/earlephilhower/arduino-pico

If you are using the earlephilhower implementation of the Arduino Core for Pico, wifi is documented here: wifi docs

rp2040 is really powerful its not a conventional "desktop" raspberry pi, its a microcontroller similar to stm32 or the avr boards that the arduino uses. https://github.com/earlephilhower/arduino-pico for arduino support.

Do you want to do serial communications along with USB HID (keyboard)? Sure, you can do that with TinyUSB. I've done it with the arduino-pico core: https://github.com/earlephilhower/arduino-pico

In the Pico SDK repository, find the external/pico_sdk_import.cmake file

https://github.com/raspberrypi/pico-sdk/ links to a PDF about connecting to the interwebs with a pi pico.

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

There is an official sdk in C and C++ as well as a really thorough sdk guide, and a separate "getting started" guide which shows you how to upload files using command line and vs code.

Arch is using Gcc 13.0.1 and there's a bug fix that I had to manually apply so that uint16_t could be resolve. See https://github.com/raspberrypi/pico-sdk/pull/1318/files.

the LED of the W is hooked to the wireless chip. in the c sdk, the function to tell the chip to set it's gpio pin(s) is: cyw43_arch_gpio_put(CYW43_WL_GPIO_LED_PIN, 1); where CYW43_WL_GPIO_LED_PIN is the macro to the LED.

The latest release of the Pico Software Developer Kit (SDK) version 1.5.0 is a significant milestone in that evolution. This new version includes many exciting features, the most notable of which is Bluetooth support. Read More - https://bit.ly/3Yyb0qi
