In the previous parts, I had been using an arduino mega and a TFT display. If you swap out the arduino mega for a 32 bit microcontroller like the esp32, then you can use TFT_eSPI. Which is in part 4b – currently unpublished because I’ve been distracted by a device that I need to make […]

Previously – an overview of the particular screen I’m using In this post I’m going over the actual display functionality. So we’ll finally have something that draws stuff on the screen instead of just messing with the touch/sd.   Compatibility In part 4b, I use TFT_eSPI, a popular library for TFT screens that is able

Previously – an overview of the particular screen I’m using In this post I’m going over the SD card functionality For this, I will be using an arduino mega compatible device. But any arduino with SPI should work just fine.   SPI and CS SPI is the Serial Peripheral Interface. SPI is similar to IIC but

Previously – an overview of the particular screen I’m using In this post, I’m going over how to interface with the capacitive touch functionality. As previously mentioned, you have to interface with SD, Display, and Touch separately For this, I will be using an arduino mega compatible device. But any arduino with IIC support should

Recently I bought this touchscreen for an upcoming arduino project, when I picked it out, I knew that the documentation would probably be ok at best, as is typical with these brands of unknown reputation, but when I found myself having to piece together how to use the thing based on amazon reviews, I decided

Sometimes you need to wait for a cancellation token, or for a fixed amount of time. For example, you may be implementing some sort of automatic retry with exponential backoffs, but also with the ability for a user to try to force an immediate retry. You can use a cancellationToken, but wait for it with

Benchmarking, especially micro benchmarking is a pretty complex topic. And the .net runtime makes things even more complicated. You have your usual problems like making sure your code does the same things in each test, and that your timing is accurate. But .net also introduces JITing, and runtime optimizations. So you could start off writing

This will undoubtedly go down as one of those things that is unsearchable on the larger internet. So if somehow you have stumbled onto this, congratulations on also being interested in really esoteric things. git has a thing inside of it called snapshots that are fundamental to how git works. This has nothing to do

The Elgato Stream Deck is a really nifty series of hardware devices. And if you’re researching how to write plugins for them, then I won’t bore you with the details of what they are, or what there’re for. I’ll just say that they’re neat, and their biggest issue with growing the market is that the

Recently I’ve switched from using VMWare Fusion to Microsoft Remote Desktop for my windows needs (thanks a lot apple for screwing me over with the switch from intel). And one of the biggest problems that I’ve been struggling with has been that while VMWare Fusion does a remarkable job preventing the mac os menu bar
