@jimf99 Thanks, Jim. That's very kind. I also have another Freenove projects board for the raspberry pi which I've added to so that I can use it with a Pico for Paul's other classes.

@peterkarlsson7801 Thanks, Peter

@leeg.1402 Thanks, Lee. I've been doing more with the Pico recently but I realised that, unless I caught up with the Arduino lessons soon, I never would. I use RecMaster which isn't too complicated. I wouldn't be able to cope if I kept switching views and resizing things like Paul does🙃I originally got RecMaster on a free trial but liked it so much that I actually PAID for it. Please do start making videos. It would be good to see what you've been up to.👍

@keithlohmeyer At least you've never been blocked in the live chat session!! The trouble is that he makes his lessons too far ahead so that, if someone points out an error or a better way of doing something, he will carry on doing it the old way FOR EVER. An example is testing for a button push/release. He also seems to have no interest in learning the intricacies of the languages. Learners ought to be taught that cut-and-paste is not your friend! I actually learn more from looking at Pascal's, Peter Karlssen's (and your, of course) programs. WHERE IS PASCAL???? I'll take a look at your distance sensor video sometime. Does it have any bears in it?

@@charlotteswift "At least you've never been blocked in the live chat session!!" OUCH! Yes and he wonders why his viewership is declining. BTW I am heading out for a week long road trip today so will be away from the computer most of the week. Hold the fort down while I am away.

@keithlohmeyer I hope you have a jolly good time.

@vaughntaylor2855 Thanks, Vaughn😊 My next mission is to convince everyone that there are 9 PIO commands available, not 8. 🙃That will be a lot harder😀and, no, I'm not counting nop.

@peterkarlsson7801 That would be interesting

@peterkarlsson7801 Thanks, Peter. I forgot to put the button debouncing back into my program when I made the video so I actually used more than 16 instructions. Are you going to make a video to show us how you did it? David aka Very US Mumblings used x_not_y but I found it all very confusing🙃but that was probably because his program still had a bug in it when he made the video. There may not be any nop()s in my video but there are elephants🐘🐘👍

@VeryUsMumblings Thanks, David. Is it the prize for the most boring program in the world?

@VeryUsMumblings I tried to leave a comment on your video but YT wasn't having it!! It was one of the most confusing programs I've ever seen🙃🙃I tried it out. Maybe I had a typo but it started counting from 2 which was weird. I'm going for a valium and a lie down😁

@@charlotteswift UA-cam is deleting my comments for some reason. I see them on my edit page, but they disappear when I go to read them. I can copy paste my reply here, if that helps. Yes, I solved it after I made the video. at the start of pio_Prog, i set x to 1111, but that's taken care of in the wrap loop, so, instead, it should set the isr to 0001. the x_not_y is needed to jump over the imcrement of the y upwards through the isr. basically it makes extra loops counting down x from 1111 to 0000 every time until x and y are the same, putting more nops in the way. As far as the invert is concerned, I just missed it or didn't understand it. do better next time, I guess. 😄 Thanks for the comment! 👍

@VeryUsMumblings You should say 'Thanks for the mean comment! '👎

@@charlotteswift That's not mean. That's just curious. Mean people drop f-bombs and write in all caps! 😄

@keithlohmeyer Thanks, Keith but I have to correct you. I'm not clever, I'm bonkers!! Who in their right mind would want a LED to delay for over 2 years?? Thanks for watching and I'll take a look at your video soon.

Most of the time, we don't need a delay of 2 years. So I think it's better to set y to 31 in the delay loop, and insert some nop() [31] instructions to adjust the delay.

@paulmcwhorter Thanks, Paul. I'm trying to get my head round multiplication now.

At 2000 hz you might get away with a single 31 cycle pause as it will get you 16 ms and you can tack it on one of your existing instructions but more is better if you have the instructions to spare. You and Carter have done such a good job on this I have nothing to add except maybe using jmp pin for one of the buttons but you still have to use in_ for the other one.

@keithlohmeyer Thanks, Keith. I was aiming for 50 ms but put 5 instead of 3 by mistake🙃

@arnoldschmucker9977 Thanks, Arnold

@quaternion-pi Thanks, Carter. I was quite lucky that I had already made a binary counter and therefore realised that's it's much easier to count backwards than forwards. It's strange that there are so few commands available. You can keep the trophy 🏆. You earned it fair and square and I wouldn't want to have to dust it anyway😁 Everyone says that there are not many examples of using PIO and micropython available so maybe you could make your video public? When I watch your videos, I see how a grown up does it👍as opposed to some of my bonkers ideas.

@@charlotteswift Charlotte, your posted solutions are very thoughtful and well explained. As far as making my video public - I am too thin skinned. I make the videos mostly for myself and to ensure I finish the project quickly. I do enjoy speaking especially with you and Keith about this material - members of the hardcore "top tech boys". This guy, David, taught me a lot: ua-cam.com/play/PLiRALtgGsxmZs_LXGkh09Zr2NUmk_mtEI.html. Way above my pay grade, but very well explained. Thanks for your thoughts!

@quaternion-pi You're very kind, Carter. I am a bit sensitive about my videos too. It upsets me when I get a dislike because, if there's nothing about the content to dislike, then it must be me that they hate😿I deliberately don't put any tags on the videos so that they are less likely to come up in searches. Like you, I mainly make the videos for myself so that I can remind myself of how to do something when I've forgotten (probably the following week🙃). Keith is very good at finding things out and @peterkarlsson7801 can be relied on to know things about the lower level stuff. I've looked at Life with David fairly briefly but it's very disappointing when he starts using C instead of micropython.

@leeg.1402 Thanks, Lee. There must be many ways of doing it because Paul said he used all 32 commands and I did it in 16.

@keithlohmeyer Thanks, Keith. As you know, I don’t google anything. I have no idea about the bit manipulation increment trick. I just thought about it while I was in the bath. I am definitely not a hunter gatherer!. l’m far too lazy!

@@charlotteswift I wish I had a brilliant mind like you!

@keithlohmayer You obviously need to spend more time in the bath!

@@charlotteswift If I didn't Google or remember things I "hunter gathered" in the past, I would probably sit in the bath trying to reinvent the wheel.

@jbelmont72 Hi J (jack, john, joshua, jimmy?) You're quite right, redBlinker is only called once (by the one shot instance of redTimer). This is to set up the moment when the periodic instance of redTimer should be set up. Imagine that the red LED wants to be on for 1 second and off for 2 seconds. Both periodic timers would have a period of 3 seconds and would just toggle the red LED. The toggling for the 1 and 2 seconds example would work something like this: 0 seconds: state = ON 1 seconds: toggle (state = OFF) 3 seconds: toggle (state = ON) 4 seconds: toggle (state = OFF) 6 seconds: toggle (state = ON) 7 seconds: toggle (state = OFF) 9 seconds: toggle (state = ON) 10 seconds: toggle (state = OFF) 12 seconds: toggle (state = ON) The 2 timers work independently to each other but, as long as the period for each of them is the same, they will remain in sync. Does this make any sense at all? In your program, you could increase the red period so that it would be easier to see what's going on. eg 0.5 seconds on and 4.5 seconds off. I've got my pico set up for something else at the moment so can't try out your program. I haven't gone through it line by line but I've just noticed that the line above def redBlinker says redOnP=int(redP+redOnPerc) instead of redOnP = int(redP * redOnPerc) This would explain why things aren't working properly. redOnPerc is the percentage of time that the red LED should be on for.

@@charlotteswift Thank you for helping me immensely. Your thoughtfulness is greatly appreciated. I look at your programs and explanations as taking PW's work to a more in depth and greater understanding level. Respectfully, Judson

@jbelmont72 You're very welcome, Judson. Some of my solutions are totally bonkers because I try not to google other people's work and I'm too lazy to read the documentation often.

@lorisrobots Thanks, Lori. I hope the wedding went well.👰🤵🎂🍾

@lorisrobots Thanks, Lori. I've fallen behind on the Arduino lessons too. I'll try to catch up by doing 5 programs in 1 video again which means that I'll get fewer dislikes.😁

@leeg.1402 Thanks, Lee. You can also get bi-colour ones that have a green and a red element so that you can display red, green and yellow. I wish I could find them🙃

@peterkarlsson7801 But not very exciting👎

@peterbrylka7877 Thank you, Peter. That’s very kind of you to say so.

@gabriel38g That’s because boys are too rough!!

@@charlotteswift LOL!😄

@peterkarlsson7801 Ah, you do it the grown up way because you read the documentation! I just pictured in my mind how the binary string looked exactly how I wanted the LED array to be. PS Whenever anyone says that my solution is 'interesting', they really mean 'strange'😺

@anthonyorf8827 That's probably because you've installed it into a different version of python. Maybe this video might help you ua-cam.com/video/S-yTMuC-adA/v-deo.html

@@charlotteswift thx, for now I found a temporary loop hole, I went to the file location of where mpy_cross was installed and copied it to the folder of the file I wanted to convert was in, then when I moved to that folder and imported, instead of being in the library it was in the actual folder, I was pretty surprised it worked

@@anthonyorf8827 Maybe that's the equivalent of what I did. I can't remember🙃🙃Perhaps I put the file that I wanted to convert in the same folder as mpy_cross. This is why I make videos, not just to help other people out but also to remind myself of all the things that I've forgotten.

@keithlohmeyer Thanks, Keith. If I wasn't so lazy, I would have created a debounce class but then I probably would have forgotten to ever use it.

@scottpettygrove7821 Thanks, Scott. I don't know whether anyone apart from Keith has used my idea of using a class to avoid having to use global variables. I just cut and pasted the emojis themselves via WordPad. A more sensible approach would be to have a dictionary with the names and unicodes of the emojis that you want. For example emoji_dict = { "grinning cat" : chr(0x1F63A), "grinning cat with smiling eyes" : chr(0x1F638), "cat with tears of joy" : chr(0x1F639), "smiling cat with heart-eyes" : chr(0x1F63B), "cat with wry smile" : chr(0x1F63C), "kissing cat" : chr(0x1F63D), "weary cat" : chr(0x1F640), "crying cat" : chr(0x1F63F), "pouting cat" : chr(0x1F63E), "Big Burger Face" : chr(0x1F920), } for key, value in emoji_dict.items(): print(f"{key}: {value}") print(" Hurrah!! It's BBF!!!", emoji_dict["Big Burger Face"]) PS Do you get the feeling that I like cats (and BBF)?😸

@scottpettygrove7821 Hi Scott. Your channel says that it doesn't have any content. Is it something that you've done or has UA-cam eaten all your videos?

@@charlotteswift Hi Charlotte. I deleted them all after someone subscribed to my channel who is a potentially bad actor. He left his playlist public and when I looked, there was zero interest in programming but tons of interest in things like survivalist training, how to handle knives, how to carry them unseen, and other subjects that caused me concern. I decided that I just don’t need to put myself out there in a way that makes it easier for folks to glean info or use AI to simulate my voice. If I submit future homework’s, they will not be narrated.

@scottpettygrove7821 That's very strange! I don't know whether my playlist is public but if it is, it would be about knitting stitches, how to make rag rugs and (obviously) cats. I never got to see your breakout game😿 Carter (quaternion but I've probably got the spelling wrong) makes all his videos so that you need a link to watch them. I can't see that learning how to flash an LED on and off would help a homocidal, knife-wielding maniac but maybe you're right to be cautious. I much prefer narrated videos. I hope that I'll be able to continue doing them but I'm having medical problems and I'm noticing a decline in my speech and manual dexterity which is a bummer. Maybe I could use AI to simulate my own voice. Or maybe it would be better to sound like Darth Vader👍👍👍😸I'll miss your videos😿😿

@-MYkus- Thanks, Mike

@gabriel38g Thanks, David. The square around the face just happened. I wouldn't have a clue how to do it🙃

@bigbogeyface That's because you're a happy chappie😁

@peterkarlsson7801 Thanks, Peter, but that would be cheating!! I'm actually much better at Pong when I'm not trying to make a video at the same time.

@peterkarlsson7801 Yeah, I would totally make the panel length 8 😄😅🤣

@gabriel38g Thanks, David. I forgot to show the version using a variable number of LEDs. ua-cam.com/video/IPjzDj4Bhjo/v-deo.html

@DrDave327 Thanks, Dr Dave, but I forgot to show the version using a variable numbe of LEDs. Here's the link in case you're interested: ua-cam.com/video/IPjzDj4Bhjo/v-deo.html

@bigbogeyface and short👍😁

@@charlotteswift and short 😃👍

@peterkarlsson7801 Hi Peter I had thought of using Neopixels but a binary counter on a Neopixel ring would be even more confusing than my Italian traffic lights🙃 About 5 months ago, I made a video about using direct port manipulation on the arduino uno and you pointed out that it would only work on an R3. You also said that you had managed to do the same thing on an R4. I am about to get my R4 out of its box because Paul's started doing lessons on the little LED matrix. I would be _really_ grateful if you could send me your DDM code for the R4 because I'm no good at reading documentation. Sometimes you need to already know what they're talking about in order to understand what they're saying🙃Looking at an example that works would help me a lot. Thanks for watching!!

@keithlohmeyer Thanks, Keith. I thought I ought to publish it after seeing Arnold setting up 8 timers one by one.

@peterkarlsson7801 Even for you?😁

@scottpettygrove7821 Thanks, Scott. I'm glad that it could be done so simply - Keith's lambda functions made my head hurt🤕

@bigbogeyface Thank you, Mr Burger. It's so simple when you know how😆

@shawnlowe1392 Thanks, Shawn. Third time lucky!!
