 Welcome to Skalidiata everybody and welcome to my desk. Happy weekend everybody. Just a quick check-in I've been working a ton on revisions. It's not as much new hard work coming out of my desk He said I'll go in the waves and now we're in a little trough But I thought I'd show off some samples that I got them checking out so if you can go to the overhead You got some more displays. This is a 960 by 320 resolution screen, but it's like really big Compared to the little bar display. So I kind of like I mean it's gonna have chunky pixels But this is cool. This is like starting to get close to like, okay cyberdeck display type and then we have these round four-inch displays in the shop and I wanted to get a version that has the Capacitive touch overlay. So you see here. I've got it when I'm all code We'll spin this around So You know, this is a display that runs off of the these both are 40-pin RGB 666 displays They'll run off the qualia. One thing that's kind of nice is that Usually when I get capacitive touch overlays, they connect onto this like on board FPC contact area over here. This one doesn't so that's kind of a little annoying because it would be really nice if this Flex kind of came around and attached here, but has a separate six-pin connector So we'll have to make a little breakout board to attach to the capacitive touch. This is a good ex GT 9-11 9-1-1 part number. I think coma. It's yet good ex GT 9-1-1 Yeah, all these capacitive touch drivers are very very similar So that's not the problem. It's just like You know, the what's nice about the ones that had the built-in the touch that goes through here Is that I have connect through this here to the ESP 32 s3 And it's like there's no dangly bits left over, but that's okay. So anyways, this is You can see I've got the in the eyeball code working One of the things that I you know is I don't know if you can kind of see but there's a little bit of like a pulse aiding Effect it's a very light flicker effect caused by the frequency and stability using the board support package for ESP version 2 and There's actually a new version of the boards for package So we go back to the computer and we'll talk we'll talk about that because there's a lot of pieces so Espresso just did a major major release update for Arduino and C support Where it's called three zero zero alpha two lived in zero zero alpha and zero zero alpha two So there's a lot more there's new boards coming out like the H2 and I think the P The C6 and then also the P4 is gonna come out so more chips are being supported, which is really great but a lot of The API's have changed like you know the when the big number changes API's break middle number of minor fixes that you know might need little tweaks And littlest number of bug fixes so your code shouldn't change is just one better But as the 3x is a big is a big change. I think two Last time they did a major release. I think 2x was probably when they added ESP 32 support. So that's how long it's been so You know, there is This is still alpha and a lot of people actually aren't using this yet because in order to get this you have to have Set up your Arduino ID to install Pre-releases which are CI does so our continues to use for all our libraries We always grab the very latest version of the ESP Boards for package so even if it's not released if it's a alpha or pre-alpha and that's because we want to make sure that We verify a lot code works for like the upcoming changes and so some people were asking us like hey Why do you why are you breaking? Why is the CI like breaking my code? It our CI isn't breaking the code We're just testing against code that is going to break your code because that's what major releases do so for example Neopixel was actually no longer working because one of the biggest changes is in RMT which is the ESP peripheral that handle stuff like I think like PWM and infrared and like Sending pulses and receiving pulses and stuff like that. So I did make the change Thankfully they published an example of like doing Neopixels and so I was able to like kind of shove that in and I tested this With the latest Boards for package and this works and you know, I do this It's a little bit gross, but I just sort of just check you can see here I check, you know, what version of the IDF are you compiling against and if it's five like Just include this like I don't try to like do in line if deaf whatever stuff I just say here's a chunk we're using for idea five and if you're having to use idea four use something earlier and so you're gonna see a couple of these things come in as You know this the board support package Five, you know, it's a support package three distributes out to You know the release candidate coming next week and then eventually the release they do have Espressive has notes The release notes, but they also have a migration guide, which I would recommend checking out They go through all the changes and like a lot of people are gonna be affected like stuff like even the analog digital inputs and Like you know the the ADC API change ITS totally changed the PWM which was using LEDC totally changed this is affected whippersnapper like, you know, Brett who does the Arduino whippersnapper code Bumped like he slammed into this last week. It was like, oh, no, like, you know, they serve a code I have doesn't work anymore, but thankfully he used a level of abstraction Anyways, you know, just letting people know that this is coming down the pipe So that's kind of actually what we've been working on the most This week again, not as much hardware because I've been doing a lot of firmware and software juggling But you know testing out these these cool display samples and hopefully those will be in the shop soon Okay, well, let's go to the great search The great search run to buy did you key and a fruit every single week lady There's a power of engineering help you. Yes, you find the parts you need on digikey.com They did what is a great search of the week this week. Okay, so this week I saw this really cool thread by this person Rue Moore And they got a snaptron design guide and you know, they posted this really neat video So there's a demo of this series from snaptron. You can see they are snap-down switches But they have LED back lights in them, which is like very very neat so You know the first place I saw snap down switches was the pocket chip which had if I zoom in here It had dozens and dozens like maybe, you know half half a like sorry like five hundred six hundred that's 50 or 60 hundreds 50 or 60 a couple dozen snapdown switches that were laminated into a piece of plastic and then Place on top of the PCB and you know, this is a much less expensive way of manufacturing And yes a much lower height like you don't have the mechanics of like, you know This switch with pads and then above it, you know an actuator Your your your fingers the actuator and then of course you can put an overlay like a vinyl overlay that has legend on it and you know, you can use this for That you use that to label the buttons So like, you know, I have these low cost remote controls and I had it I was a kid at a calculator that had these little pocket calculator with dome switches So inexpensive easy way to add a lot of buttons and I think you know, this was a perfect example of of Dome switches so snaptron. I guess the whole thing is they make dome switches. This is like a pretty sweet hero image Demonstrating all of their products. So like really big ones teeny ones. They come on tape so you can pick and place them very easily and They do have a couple different Families here, I think the DT series is very cool, but in case you're like, oh, man I want like that kit too. You can get That same design kit that was shown off in this thread here With like all the different sizes and like the demos and you can feel them and click them to your heart's content Go to digikey.com slash and slash supplier center slash snaptron And then scroll down here and you can pick up your dome kit for free. They give it. It's a sample I believe they will ship it to you if you give them your your name and address But some of the series that I thought was very neat here was, you know, particularly the The dual tactile dome S switch So what's neat about this is there's two Two contacts. There's first like this. So you solder in these three Pads and then this one is left kind of like floating. And so when you first press This contact will touch first and then when you press in even more the center contact goes in and And here's that this detail about the peel-in-place Which is a little more this is a kind of neat So, you know, you're ready to go sheets that you just press on so instead of picking a placing like dozens of switches You just paste You tape this on, you know, using a jig and then all of your buttons are placed instantaneously because you don't actually need to solder them Down they can make they can use mechanical Contact instead of soldering. Although you can solder these as well So these are dual. So I get distracted. These are the dual series and This is how You know, you soldered in and then you see this part makes contact first and then the second contact so there's you can have up to two Detections for like soft and hard press and You can also get them with or without the ability to have a backlight Which is also very neat So these are all available at digikey. So if you just search for Metal dome switch and They're gonna be under tactile switches and there's a couple other vendors But you know, I'll say snapped on very clearly like kind of has the market here. You can Get different operating forces. They do start kind of higher than tactile switches and You're also going to see like, you know, they're also gonna be, you know, the word Metal, you know, it's in in the description of other ones even though the ones that have the The hole for back illumination, you're gonna want the LED behind the PCB. So it's gonna be reverse mount that's going to be It's gonna come because not illuminated so let's go for active snap down and And then this will get rid of like some of these, you know, random things that came in so you can see like snap Tron really kind of like has Kind of has this whole thing nailed down like just searching for Snap metal dome is what you get but they do have them in multiple different sizes With lots and lots of stocks. So 10 6 8, you know, every any size millimeter from very large to very small The dual touch the ones that it's like you can press and then press again. Those are called DT BL Means that they have the hole and I think like the next two numbers are the Yeah, that this number the 12 means 12 by 12 millimeter and then 450 n is the Amount of force you need to press it. So, you know, this these are both dual touch back lit 12 millimeter And this one is 540 and so it's going to be very tough to press and this is the 340 and a lot lighter to press So, you know pick and choose from from your desired setup. There's tons and tons in stock There's also these that are they're non dual touch. It's like you just press once But I like the dual touch ones. I thought that were pretty cool. So I Think my pick is going to be. Oh, I don't know this one went on Dual touch and backlit very cool. I didn't know that you could even do that with Um metal dome switches. So I learned a lot today. So this is my pick for the great search And that's research All right, that's our super quick check-in. I down three quick. We got to go back the last thing was like 40 minutes Yeah, that's how it goes. Okay. All right. We'll see everybody during the week this week. Have a good night. Thanks everybody
