Finished MCU and Schematic

I finished wiring up the MCU and made the final touches to the schematic. Now, the only thing left to do is to route the PCB.

Started Wiring MCU

I started on the MCU wiring, including adding in the buttons and crystals needed for it. I also added in the jst connecters for the ESC and camera (I decided to add it in).

Connected MCU

I connected the MCU to all of my peripherals, not wired yet though. I decided to only use one DIO pin from LoRa, I might use more later but for now only 1. Now, I have to wire this in KiCad along with the remaining few components.

Wired GPS

I finished wiring the GPS component, including adding in a connection for an active antenna, which the GPS needs. Next, I will either wire the MCU or LoRa module. I still have to figure out weather I want this to be able to use a camera.

Finished wiring MicroSD and Magnetometer

I finished wiring two more important components of the flight controller. Now, it’s time to work on the bigger components like GPS, LoRa, and MCU.

Finished wiring more components

I finally finished all of the power components with the wiring of the 3.3V buck. I also started out on wiring the sensors by wiring the barometer and IMU. Next, I’ll finish wiring all of the sensors and wok a little bit on LoRa and GPS.

Finished wiring 5V buck-boost

I finished the wiring for the next part, which is the 5V buck-boost. I also added in the correct parts for the inductors because they needed different models.

Finished wiring

I finished the wiring for the battery charger and I completed my research on ESC’s and how to integrate them into my current design. Next, I will wire the remaining components as fast as possible because I want to move on.

First steps

I started out on planning the flight controller, I got the basic parts but I still need to plan out the whole architecture a little bit more. I also started out wiring a few of the parts.

Finished screen!

I finally finsished making the screen compnent. It finally works in logisim now. Turns out the problem was my compiler bc it wasn’t compiling the RGB correctly, there were also a few small issues in the circuit.

Added screen and drawing to emulator

I added a screen component to the emulator and allowed drawing to it. I also added an example code that draws a rectangle and square.

I still have to test it for Logisim, I added it to the compiler but I know something is going to go wrong and I don’t want to debug for hours today.

Added a screen

I added a screen component to my project because I wanted a way to see the CPU in action without looking at the vague data memory.

I still have to test it and integrate it into my assembly language and compiler.

Updated UI

I made the UI look a lot cleaner in my opinion, it could still look better, but this is the best I can do.
Write your feedback in the comments!

Music app

I added a music app with 5 different choices of music (all instrumental because they were they only free downloads I could find). I’m going to ship now!

Two new apps!

I added two new apps! You can now open Google in SimpleOS and you can also change the background color.

Worked on feedback!

• Thanks for the feedback! I worked on some of it like a thoughtful comment which pointed out a little bug in my label storage and jump code. (I stored labels with $ but looked them up without $). This also led me to finding out another bug where my code didn’t actually start at label $start. That was a 5-second fix.

• I also worked on the README.md after recieving feedback about it.

• I plan to work on some more feedback later (specifically updating my website UI). I thought it was fine because I have barely any experience with JS/HTML/CSS, but there’s no excuse for bad UI.

PS - I also added comment functionality to my Assembly

New app!

I just made a timer app. I couldn’t think of any ideas for apps so I just went to some default smartphone apps, and ended up choosing a timer. If you have any ideas, I’m open to them. Just comment on this devlog.
