Raspberry Pi Picoprobe Debug Setup/Tips & Tricks

This document details useful information on how to use a Raspberry Pi Pico as a SWD probe for another Pico using the Picoprobe software. This information assumes you have followed all of the steps in Appendix A of the Getting Started with Raspberry Pi Pico Guide and that you are doing development on a Linux system.

Essential Setup

Add the below files to your system to enable non-root access to the devices

/etc/udev/rules.d/99-openocd.rules:
```
# Raspberry Pi Picoprobe
```

ATTRS{idVendor}=="2e8a", ATTRS{idProduct}=="0004", MODE="0666"

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

	# Function to convert millidegree Celsius to Fahrenheit
	convert_to_fahrenheit() {

	# Convert millidegree Celsius to Celsius
	local temp_c=$(echo "scale=4; $temp_milli_c / 1000" \| bc)
	# Convert Celsius to Fahrenheit
	echo "scale=2; ($temp_c * 9 / 5) + 32" \| bc
	}
