Re: Problem installing micropython

I've done it and it was easy once I found the list of release files at https://github.com/thonny/thonny/releases I didn't do it the way instructed Linux: download thonny-3.3.4.bash and execute it with Bash (bash thonny-3.3.4.bash) I downloaded it made the file executable and did ./thonny-3.3.4.bash ...

I've read lots of web pages and I'm not sure where I found everything. You may not want the details but I want to find where I got the info I followed so it can be corrected or made clearer (or I find where I went off piste). Yes I'm on a PC running Ubuntu 18.04. and was following instructions on ht...

Re: Problem installing micropython

Assuming Thonny is the way (or a way ) to go, how do I make it talk to the pico? I'd like to be sure that the pico is working and communicate with it. At present it seems unaware of the pico's existence.

Thanks Nick, those are useful links. I've been looking for that first one after seeing it in the last few days and couldn't find it. Thanks for your helpful comments. As a result, I think I've just got a non-unstable version and transferred it to the pico using the Linux 'file manager', though I don...

Problem installing micropython

Hello all My pi pico arrived today and I'm trying to install the micropython code. I'm on the 'Getting started with Raspberry Pi Pico' project instructions and installed Thonny several days ago. The fourth page/step is "Add the MicroPython firmware" which isn't working for me. It says clic...

Happy Pi Approximation Day!

I'm just off to a pub quiz and there's usually a round on what happened this day in history, so I looked for a handy list. One thing notable about today's date - it's Pi Approximation Day: 22/7.

Re: Shift register help!

I'm doing the same, with the same chip. But an HC type chip, if running on 5V is no good as it won't read data input reliably from 3.3V logic such as the Pi. So I used an HCT type (74HCT245) as a crude level shifter. If I'd known I'd have got an 74HCT595 for simplicity but I'd never worked with 3.3V...

Re: Interfacing troubleshooting

I'm pretty much at the same stage as you are I think. But my experience of getting things working in hardware/software in the past with no test gear, I'd say keep it simple and keep asking if what you see is what you expect to see. A long time ago (for 8051 processor circuits) I made a simple tester...

OK, thanks.

Maybe the wiki indirection page and link to it could be reinstated, with appropriate health warnings.
Or maybe the useful stuff from there could be given a home here and kept safe by our mods.

Re: How to play a sound (music)? Not ogg or mp3 s!

The RPi does have an audio output, where does the signal come from? Does it mean there is a simple D/A on board? Can it be controlled?

This looks so useful - and very nicely documented too.

Re: PWM for servos, motors, and LEDs plus plus

This seems like just what I always wanted but I don't know whether to choose hard or soft float version. It's months since I got my RPi and I can't remember which OS I've got. It mentions Debian when it boots so that mean I'm on Raspian? If so which should I choose hard or soft?

Thanks.

Re: Controlling RGB LEDs

I've got a couple of rolls of those 12V LED strings and plan to do things with them. The only thing I achieved so far was to make a 'Christmas Star' which twinkles nicely. No Raspberry Pis were involved, it's controlled by an 8051 (running on 5V) the outputs of which feed a ULN2803 which can drive 5...

Re: 120V AC Light Dimmer

If you're running some variety of Linux which most Raspis will, I think it'll be hard to damn near impossible to guarantee sufficiently accurate timing for such a task. You'd be much better off using a microcontroller: PIC, Arduino etc where a very small program is all it does and you can guarantee ...

Re: Search function failure?

Thanks both.

I (a human) see 'raspi-config' as a single character string containing a hyphen because there are no spaces.
The search function sees two strings because there is an embedded hyphen, which seems perverse.

At least the mystery is solved.

You're right I haven't done that before. After it runs it goes back to the text screen so this time I've re-entered raspi-config and selected update and finish. I hope that will sort it. Thanks.
