pico-sdk VS RIOT

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

RIOT-OS is somewhat popular in academia, it tries to be very approachable but there are still plenty of low hanging fruits with all kinds of hardware and you can use it for software and thesis projects.

Just one example: https://github.com/RIOT-OS/RIOT

You could also take a look at RIOT-OS. http://riot-os.org

RIOT-OS has a lot of unit tests for all the boards they support. And it's written in C. https://github.com/RIOT-OS/RIOT/tree/master/tests

Another option is using RIOT-OS. But that unfortunately doesn't support PWM for the Weact. It does support PWM for the Bluepill and Blackpill STM32f103 and the Nucleo-f446 After quick search. \ https://riot-os.org

If you want to use C, I would suggest trying out RIOT-OS. It's a modern embedded operating system, written in C and focussed on IOT. It works on a lot of different boards. https://github.com/RIOT-OS/RIOT

Alternatively, you can also write your code in an RTOS. They often have scripts that make flashing and debugging easy. One that I personally like, and also supports Arduino, is RIOT-OS.
