 Okay, so for top secret we're gonna show three videos see on the other side and then We'll do a couple questions and then get out of here Related what is this? Well, usually I'm showing off a tester that has Pogo pins But in this case I'm gonna show how I'm building a tester for this revision of the TFT touch shield So the micro SD card I want to test that as a display and as a touch driver So to test all that stuff too and all these connectors. So in this case, I'm actually using Metro RP 2040 We just put these in the shop and they're very low-cost and I don't have to worry about You know that you have two boot loaders built in so they're a lot more reliable And in this case it's got a little code that's looking for an SD card and when I insert the SD card It looks for an image called wolf and then I can test the type screen And so this is a great way for me to Give the test prep folks at Adafruit a quick way to test all the functionality for this shield So we can get into the shop very quickly. So this just needs to get taped down and You can see the tape on the back put it on there. Bam new product Really do what is this? I'm testing out some displays that I found in some bands. I really is a long time ago These are three point five inch capacitive touch display So I made a breakout board with an iSpy connector and you see I made a little mistake But I fixed it some blue wire hacks And then I've got it wired up here to an iSpy BFF on a cutie pie and Just testing out the capacitive touch display something interesting about this display is actually it's multi-touch capable So I can put three fingers down and you can see it detects The three touches and draws them with different colors. I'm kind of neat Actually has like five multi-touch so you can see it's got four or five fingers all can touch at the same time This chip doesn't actually support gestures. You'd have to do that on the micro controller It's an unfortunate side effect, but otherwise it works pretty nicely So I'm gonna wrap up fix that little mistake and then we'll get these nice 480 by 320 displays into the shop Early do that was this this is me testing out a 2.1 inch capacitive touch IPS display that uses RGB TTL. It's a 18-bit color display at 480 by 480 so it's actually like a high resolution display, which means it doesn't use SPI It uses parallel RGB and usually that's really hard to do it on my controller But the ESP32 S3 can do it I'm doing ESP32 if it's got enough PSRAM and then this board this is actually in a valve board called the LCD EV and this originally came with a square display But one fun fact is almost all these 40 pin displays are the same pin out So I had to update the init code and the capacitive touch drivers a little bit different too But I got it working and that Arduino library and then circuit Python is coming up next So this is looking great getting those cool displays working one at a time that lie from nature sector Okay, so that's the eyeball eyeball and we're working on this and then this was the intro So anything to add before we want to show this real fast hold it up I mean I can just show it on the overhead. I think you know that's real the video Was pretty good. So this is a four inch display and then also get a version of this that has Capacitive touch this one does not have touch so you can poke yourself in eyeball all you want But I mean like it's so it's so cool and weird Great for Halloween. Maybe we'll have it just in time. So You know, we have there's an Arduino library that can support these And I just have to program in the init code and then Jephler has been working on circuit Python support You do need to have something like this Metro ESP 32 s3 which has 8 megabytes of ps ram because these displays unlike the 3.5 or 2.8 or 1.2 inch displays the small ones Those have built-in memory. This does not you have to draw the screen Constantly so while it looks like nothing is happening actually a lot is happening. It's constantly redrawing like every second sorry every Point every 50 Hertz whatever 60 Hertz It's redrawing the display, which means that you get very fast redraws But you have to have the memory for the display Buffered inside of here, and it's constantly like outputting it So the only thing I don't know is if it's doing this kind of display output You know, is that happening on one core and you can do Wi-Fi on the other core And how does this work with the octal ps ram because like can you do stuff during like the you know V-sync or does it buffer? I don't actually understand how it works But I'll definitely be learning more about it as we're pushing the limits because that would be cool to make like a round pipe portal Like literally it's a portal and you can like show stuff from the internet, but it's round So yeah, I wanted you know, we asked you like which ones should I do and you said do the round ones So I did the I did the round ones. Yes, nothing illustrates what we're up to other than giant eyeballs. Okay, that's
