In my latest discovery, I found an incredibly efficient visualization tool from the last outpost workshop that upgrades how I check the status of the GPIO pins on my ESP32. It's super simple to use and allows me to monitor pin activities directly. I set up a couple of LEDs and a button on various GPIO pins to demonstrate its effectiveness and the results were fantastic. Although it currently supports only digital input and output and PWM, I'm optimistic it will expand with time. Thanks to the open-source community, you can find the setup instructions in a GitHub repo. This tool is a revelation and I highly recommend it.

[0:00] so I came across this really cool video
[0:02] from the last outpost workshop I’ll put
[0:04] a link to it in the description it’s a
[0:06] really simple way of visualizing the
[0:08] status of the gpio pins on your
[0:11] esp32 so I got it installed locally and
[0:14] I’m running my esp32 with a very simple
[0:16] sketch I’m blinking these two LEDs and
[0:19] they’re connected to
[0:21] gp25 and gpio 26 and you can see these
[0:25] turning on and off so that’s a really
[0:26] cool visualization of what the USB 32 is
[0:29] doing I’ve also got an LED the red one
[0:32] attached to a pwm output so that’s on
[0:34] gpio 33 and you can see this counting up
[0:38] and the LED is getting brighter I’ve
[0:41] also hooked up a button and that’s
[0:43] connected to gpio 21 and you can see
[0:45] that that is currently low if we push
[0:47] the button it switches to high and I
[0:50] Fook that through to gpio 32 and that
[0:53] turns this led on and off so it’s a
[0:55] really amazing way of just visualizing
[0:57] what your ESB 32 is doing it’s really
[1:00] simple to set up there’s a GitHub reper
[1:02] with all the instructions you need and
[1:04] it just needs a few lines of code so
[1:06] definitely check out the GitHub reper
[1:08] and have a look at how to set it up is
[1:10] very simple there are some limitations
[1:12] it’s currently limited to digital input
[1:14] and output and pwm so you can’t do
[1:17] analog or i squ s or i squ c but I’m
[1:20] assuming the guy’s going to carry on
[1:21] working on this and it should get pretty
[1:23] good so check out the link in the
[1:25] description to this guy’s video and his
[1:27] GitHub repo I recommend it it looks
[1:29] really really interesting
