Thanks.

Yes, the toilets here can be dangerous - red-backs on the toilet seat, etc.

And here is is coming on summer and it is going to be a bit of a hot one. Although others say it is going to be wet.

But the new few days the temperature is going to be like 40 degrees Celsius.

Again: Thanks. I will not be able to test this for another week and at a place where they have only just discovered electricity. (Sorry. Oz humour. But it is out the back of no where.) :D The RasPie won't have internet connectivity. Though I fear I will have to hotspot it to get some parts working.

lerner

Wow! Thanks. That is good. Alas, there are a few "multi-artist" albums. However, there are also a lot of single-artist albums too. I'll play with it and see if it can help me. They were using an old machine - XP even! - but it is/was getting old and a bit unreliable. Alas XP is bound to 2T...

Thank you very much.

Appreciated.

I hope this is the better place to ask. Someone has a lot of MP3 files all stuck in one directory rather than via Album title. There are (obviously) no conflicts with names, but it is not nice. The metadata is there. Is there a way bash (or anything else) could parse the metadata, create a directory...

lerner

Thanks.

I may need to follow that up a bit more.

Just sometimes a physical book is good as I can have it open at ..... page `X` while looking at the screen and studying what is going on and why.

lerner

Thanks. I am asking because I recently had a whole lot of fun with the `ifup` and `ifdown` commands. Which are now deprecated. But thanks. That most commands are still there is somewhat consoling to me. Maybe I need something which can help me with the interrelationship of commands. (excusing the us...

Way before the RasPi existed and in the early days of internet, I had a dialup internet access and the server was Linux/Unix. To help me understand the commands I bought a Unix bible. But as the RasPi is a bit further down the track, I don't think that will be much good for me now. (And it is 25 yea...

lerner

Ok, I am stupid. That's a given. I can live with that. Don't really have a choice. But given what you said, there is still a big disconnect. Originally I did the whole things with pip . It worked, but didn't. I was advised to update to the v3 package. But before that happened, I wrote a script in Py...

lerner

It isn't I was wanting to flood the forum with posts, but I thought I had better separate the two problems.

I'll read the other reply.

I am going mad with a recent display I bought. That aside, I have (finally - I hope) been shown the correct / latest python stuff for it. Where I was failing - supposedly - was I was using python 2.7 and not 3.7. Slight difference in the command to invoke the script. python3 rather than just python ...

lerner

Yes, I am using Python 2.7 The link from where I got it didn't say to use python3. Just `python`. I think I have tried using python3, and it errors. Though that may be because I downloaded the `2` version. So we are both on the same page: https://github.com/sparkfun/Qwiic_Py No mention of python3 th...

Continuing. So, although a command is there to adjust the back lighting..... It prints a message on the screen for you - which I don't want - and the colour changes through about 4 other ones before getting to ...... I don't know what. I set it to red. 150,0,0 as you can see in the command. Sorry he...

lerner

(Oh you have to be kidding.) 4 attempts to upload some stuff and it won't let me. And then I lost what I had posted/typed. Here's the story (again). The display is showing a clock showing basically the time day of week and date. I enter a command to change the back light and this happens (Pictures.)...

lerner

AFAIK, this is a new package/piece. The retired one is the display without a backpack. This one has it. Thanks for the info. I was told to use the pip show <name> command and it pointed me to where they were installed. Alas looking through the code, the messages I see when adjusting the backlight ar...

lerner

Slightly off topic, but it is under the realm of this quest. How do I know where that code installs itself? As in this stuff. https://github.com/sparkfun/Qwiic_SerLCD_Py I don't know if I helped myself or not, but I downloaded the zip file and unzipped it on the desktop and set it up from there. So ...

lerner

Just FYI,

https://github.com/sparkfun/Qwiic_SerLCD_Py

Really helped me a lot.

Installed the QWIIC stuff and now it is working.
Well, 99%.

But that is good.

100% would be better, but I am tripping on some python stuff.

lerner

Well, back in the early days, I bought a "PiFaceCAD" board which was/is a 16x2 LCD and 7 buttons hat. The buttons are divided 4/3. 4 - press buttons 3 - a toggle switch. Left/Right/Press. It ..... Works, but it is painful. Alas that display is too small for needs, and so I went with this 2...

lerner

Thanks.

Shall do.

I just was wondering if someone here had already been down this road.

lerner

I am wanting to make a project on a RasPi 3a board and use a 20x4 LCD screen. https://core-electronics.com.au/sparkfun-20x4-serlcd-black-on-rgb-3-3v.html This one. Not wanting to squander pins, this one has I2C and SPI inputs. I've decided to use I2C. Partly because someone has written some code to ...

lerner

Thanks.

lerner

To keep things separate, this is a new problem for me. I have a RasPi with a LCD screen working. It boots, It seems to be working. I see the desktop and I created an icon for Chrome. If I double click the icon, Chromium loads but is bigger than the screen. (I'll get to that.) But at this point: It l...

lerner

Thanks.

I will check that link.

Appreciated.

Had a quick look. Looks promising.

lerner

Ok. Thanks. With you now. Sorry. I'm just a bit overwhelmed with things - Yeah: No excuse. Anyway, I'll work with what I have for now. Not meaning this directly at you, but I'm a bit confused. Yeah, "in the beginning....." All was good. Things work. That a kernel should then be released wh...

lerner

Thanks. I realised that after posting. The link I posted was all I had at the time. Again: Appreciated for the help. I just want to ask though why you say: But that's called burying your head in the sand or papering over the cracks as it's not a permanent solution. If the later kernel versions don't...
