 Let's do some top-secret data. Yes. From the vault. All right. So out of the things that are top-secret this week, do you want to show the SPI friend? Do you want to show the STEM thing? Do you want to show the RP2040 stuff? Do you want to show? Well, let's do this one. This is the. OK. You just emailed me one morning. He said, we should make an ink trinket. So I just pulled together. Let's show the first video, the SPI 2040, I think. Because I'm about to kill that. We also have this slider snail. Wow. Yeah. So let's do the RP2040. Yeah, the first video. Or do you want to show all of them or just one? I'm not asking which ones are the most important. Just show the first two. All right. Fresh time. Yeah. Earthly data, what is this? Hey, I'm working on my STEMFRIEND. I've updated this board. If you remember, this was a SAMD21 with a display to do I-squirt scene analog stuff helping. And I'm updating it to an RP2040, but you'll notice the display is a little slow. And if you look on the oscilloscope, it's only transmitted in one byte every couple of microseconds. So what I'm doing is I'm upgrading the Arduino core from fellow Hauer to add faster SPI to do block writes instead of individual writes. So if I reset my board and then I load on, I already pre-compiled this, my fast SPI, you'll see, boom, still fast. And then on the oscilloscope, it's writing out big chunks at a time. So it's like 10 times faster. It's awesome. Faster screen updates, more data. All right, Lady, what is this? Hey, for the I-squirt C STEMFRIEND that I've been working on, it's got this 240 by 240 screen. And I thought maybe it could be really useful also as a serial port monitor. So I wrote a little bit of auto-bod detection code. So now if I connect this up to my GPS module, you'll see it automatically detects at 9,600 bod. And it actually reads the data and displays up to the buffer with this nice scrolling. The scrolling is harder than it seems. I have to actually make a frame buffer for the entire display and then blit it out constantly. It's about 20 frames per second. But it's quite nice. It has a nice scrolling effect. And it would be a great debugging tool for, say, a GPS or maybe a Raspberry Pi. This works as well with auto-bod detection. It's kind of cool. So you don't have to enter in the bod rate. That's our secret. OK, let's get to some questions. Back in the vault. Yeah. They're very secret. That's true to the hardware version, too.
