This is the best Pico getting started video I have seen, out of more than a dozen. Some are merely infatuated with taking something out of a cardboard box, while all of them did nothing more than read the spec sheet out loud. You, on the other hand, actually showed us how to do something. Thank you. I used Putty in serial mode to get the REPL.

@Core-Electronics 3 года назад

Thanks :) Connecting by terminal is a great "need to know" for microcontrollers, and the next level up is using an IDE such as Thonny to flash your scripts to your Pico (so they stay on there forever). Oh, and we have done a guide for that as well =) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_ouzuI_ZPLs.html

I really enjoyed your video even though it's a year old it gave me a huge boost of confidence and excitement watching your video reason being years ago I actually bought a Raspberry Pi device similar to yours and it got misplaced in some boxes so by watching your video it gave me this bolt of energy to go and look for it and to do what I wanted to do years ago now I know my device is probably again years old but thanks for the video and just get me excited to get back to working in starting on I should say with my Raspberry Pi device I look forward to watching your other videos in the future as well friend. Also it was very easy to listen to you and follow you you did a great job of explaining things and your video work was just really good so great job on everything regarding your video

@MeierUTube 3 года назад

CoolTerm tip: Enabling the "Filter ASCII Escape Sequences" and "Handle BS and DEL Characters" options in the CoolTerm connection settings allows you to use CoolTerm in "Raw Mode" as opposed to "Line Mode". This gives you the same look and feel you get from the Python interpreter running on a PC. However, you will lose the ability to use the UP arrow to recall previously used commands as MicroPython on the Pi Pico doesn't appear to be supporting the UP/Down arrows.

@MeierUTube Год назад

The latest version of CoolTerm now has an option to emulate certain keys, such as the UP and DOWN arrows by sending specific ANSI escape sequences MicroPython understands. Enabling this option enables the use of the UP and DOWN arrows in "Raw Mode".

Does the Timer class require that the tick function has the argument timer? The argument is not being used inside the function.

@berndeckenfels 3 года назад

The callback function can use the argument if it wants to do things like stopping the actual timer. If the function has no argument it will basically get an error that the type does not match, however you won’t see the error as it happens in a service routine (you can define an emergency buffer if you want to see the error as documented here docs.micropython.org/en/latest/pyboard/reference/isr_rules.html ) but it’s best to just define the argument so that the number of arguments is correct, even if you don’t use it.

While I am waiting for my order to arrive I've been having a quick look through of the Official Raspberry Pi Pico Guide digital download 'Getting Started with MicroPython on Raspberry Pi Pico'. It seems that Thonny is the simplest option and comes with Raspberry Pi OS or can be downloaded for other OSes. You can write your MicroPython code in live mode or save it as a .py file directly to the Pico.

@nichtgestalt 3 года назад

So you can make a LED blink and set up a timer to that. I was wondering if you can programm some sort of morse alphabet to it and use the Pico as a minimalistic communication device? ^^ (Note here: I'm pretty new to programming and computers in general so i have no idea what the limitations of this software and hardware is. All a have is a bit creativity, thats all atm :) )

@smellor123 3 года назад

Get one and have a go! They don't have have any wireless communication on board, so you'd have to design that yourself or wait for their wifi pack from pimoroni. You could set it up with a short range radio transmitter and then have another pico set up with a receiver and a little servo to read out your morse code. Could be a great project to get started.

Hey Gabriel, are the scripts named main.py? The board will only run code named that on boot. If that is not the case ensure you have installed MicroPython correctly and that the scripts are correct. Best of luck!

At the time of writing, Thonny is the best user experience. It will gracefully handle firmware updates and makes updating code transparent (easy). Support for VSCode shouldn’t be far away; though it would be via a plug-in of some flavor

You can run CircuitPython on the Pico as well. It appears as a drive with a python file on it that you can edit from any code or plain text editor. On save, the code will be restarted. You'll need a separate serial app to see the output. circuitpython.org/board/raspberry_pi_pico/
