 Hi lady, what is this? Hey, I'm testing out a breakout eye design for the TCA 8418. It's a GPIO and keypad to I-Squared T-Expander. Can do up to 80 keys. And I've got here hooked up a 3 by 4 keypad. I can press buttons. Here's the page on ti.com if you're interested. And we'll read more about it. And here is the output of my Python code. So as I press these buttons, you see it's like, hey, key up, key up, and it has a cue, which is kind of need a 10 key cue. And then another thing is that there's an IRQ pen. And so I'm monitoring that with my scope. And every time I press a button or release a button, you see the IRQ go off. So all this is good. This is working out. I've tested all the GPIO pens and the IRQ in the reset. So this is getting ready to go into the Adafruit shop soon.
