I'll be using a lot that I learned on the Aurora project for this vehicle as well. What… ## [Project Pause(ish)](https://jacksonwhite.xyz/project-pauseish/) _2025-09-04 · jacksonwhite · Jackson White_ After some deliberation, I think I am going to put the Aurora TVC Hopper project on pause for the time being... Probably not even a full pause! Life has been very busy the last few months, and I haven't been able to really dedicate any time to the project. I've also been a little bogged down with code integration - doesn't quite scratch my engineering itch as much as everything else does.… ## [xBee Issues](https://jacksonwhite.xyz/04022025/) _2025-04-02 · jacksonwhite · Jackson White_ I am still having issues with getting the xBees working. Everything seems to work normally when they're both connected to my computer, but when I connect them to an arduino/STM32 and try to send/receive serial data, nothing happens... It seems like it should be easy? There's a decent number of basic arduino tutorials out there. I suspect there's an issue with my STM32 code/setup. Should just be a… ## [TWR Maneuverability Requirements](https://jacksonwhite.xyz/03192025/) _2025-03-19 · jacksonwhite · Jackson White_ Here is the datasheet for the contrarotating motor I'm using. Since it is a TVC/VTOL platform, I need more than just a 1:1 TWR to fly Because of cosine thrust losses , when the motor pivots, we will lose a component of the vertical thrust produced If the motor pivots 10deg, assuming a starting thrust of 1400g, the resulting vertical thrust will only be 1157g. In order to maintain altitude during… ## [LabView Groundstation](https://jacksonwhite.xyz/03122025/) _2025-03-12 · jacksonwhite · Jackson White_ Haven't started working on it yet, but planning to do something similar to ardupilot groundstation what if I just used LabView ? Maybe not as sleek as other options, but just for simple data collection it could save some headache not married to labview, just a thought Looks like a pretty decent amount of people have done drone control projects with labview, specifically about 10 years ago with a… ## [Sensor Success!](https://jacksonwhite.xyz/sensor-success/) _2025-03-08 · jacksonwhite · Jackson White_ Finally, after over a week of troubleshooting, I am able to communicate with the onboard sensors on the MatekH743! I have been attempting to read data from the onboard ICM42688 IMU. According to the Matek docs, the sensor is connected via SPI1. Since I know the board pinouts, it should've been a simple matter, just standard SPI communication using an STM32 board. However, it stumped me for over a… ## [Scanning all GPIOs for CS pins](https://jacksonwhite.xyz/03072025/) _2025-03-07 · jacksonwhite · Jackson White_ The provided code tests all GPIOs as CS pins. A response different from 0xFF likely means you've found the correct CS pin. Some sensors require specific register reads (WHO\_AM\_I) to respond. If no response: Try different SPI modes ( SPI\_MODE0 , SPI\_MODE1 , etc.). Verify power connections. Use a logic analyzer to check SPI activity. #include \ // Define SPI bus (adjust to match your sensor's… ## [Still No IMU Luck](https://jacksonwhite.xyz/03062025/) _2025-03-06 · jacksonwhite · Jackson White_ Still not having any luck reading the onboard sensors... I have gotten way into betaflight and an arduino library for the sensor, but with no luck. I am not sure why that isn't working... Next Steps: Try to read the barometer - I have only been focused on reading the IMUs, maybe I would have better luck with trying a different sensor Directly copy the relevant betaflight code for initializing this… ## [Betaflight SPI Gyro Comms](https://jacksonwhite.xyz/03032025/) _2025-03-03 · jacksonwhite · Jackson White_ Gyro SPI Comms Still can't get gyro communication working over spi, even though I think I have the correct pin defs I found this betaflight gyro config code, would be interesting to dive into. Might be able to just copy/paste it into mine... at the very least I can use the ways it wakes the gyro and stuff I think my problem has not been pin defs, but rather comms protocol? Maybe using a wrong… ## [Realtime AI Arbitrage Terminal (Sponsored)](https://crawlproof.com/a/zycrRUWdXH93) _2025-03-03 · **Sponsored**_ Realtime auto-trading across exchanges with scored setups, backtesting, and risk controls. ## [Creating a Custom Board Config in Arduino IDE](https://jacksonwhite.xyz/arduino-custom-board-config/) _2025-03-01 · jacksonwhite · Jackson White_ The Arduino IDE makes it surprisingly easy to program microcontrollers that aren’t part of the Arduino ecosystem—like STM32 devices. This is a useful feature for my project with the Matek H743 flight controller, which runs on an STM32H743 chip. It’s not a typical development board, but with a bit of extra effort, I’ve managed to get it working. Handling DFU Mode Programming an STM32 board isn’t as…
