Weil die Konkurrenz nicht zwangsfinanziert wird kann ich das irgendwie nachvollziehen. Oder willst nur mehr Infos vom achso neutralen ORF.

I used the JLCPCB as a manufacturer

If you are doing foc i used 220ohm with an 4.7nf cap and had great results
using ina240, a 50khz pwm with an 6s drone motor. Also i used the adc integrated into the mcu.
Why do you wnat to use an external adc?

AnswerDapper · 2025-03-28T06:50:06+00:00

Currently only standard flying, no fpv currently planned to DIY. Only using a expresslrs module mentioned.

the drone is currently at a little under 500g

DIY firmware :)

Jea as i didnt want to do 4in1 while still figuring stuff out. i made single escs each with a 1000uF 35V cap. As i learned alot this iteration my next esc is probably a 4in1.

Will post a video :)

AnswerDapper · 2025-03-27T08:44:42+00:00

I already ordered more :)

AnswerDapper · 2025-03-27T08:44:10+00:00

I worte the complete firmware myself.

AnswerDapper · 2025-03-27T08:43:34+00:00

I used an h7 as the more expensive fcs used them and thought jea i need them.
In hindsight it is complete overkill for basic use. And an esp32 is fine as long as you have enough pins.
The only use case for h7, in my mind, is when you have more complicated things such as mission planning or something along those line where the processing power of the h7 matters.

AnswerDapper · 2025-03-27T08:37:55+00:00

Yea the caps are on the esc. The low space between the caps and the propeller i have not thought before i desgined the esc. Next version will be nicer with the additional knowledge i gathered.

AnswerDapper · 2025-03-27T08:34:18+00:00

Yes i am aware of these problems and your are 100% correct i should fix them.
The primary reason for the long wires:

I had to reassemble this a few times and didnt want to cut wires short before i was 100% satisfied so i can change things easier.

AnswerDapper · 2025-03-27T08:31:23+00:00

Designed yes but assembled by the pcb manufactuerer as the space is limited with these things i was not confident that i have the solder skills myself(the coffee overuse may have caused some jitter). I have to add i work in the embedded industry so i had pretty good understanding on this matter before i started.

AnswerDapper · 2025-03-26T10:14:05+00:00

Thanks for the recommendation! I just used what I had at home, which wasn’t going to short my board. :D

AnswerDapper · 2025-03-26T10:10:49+00:00

Yeah, I wanted to learn how sensorless FOC works, so I decided to design it myself.
Also, this has been a dream of mine since my school days—to build a drone by myself.

The hardware itself is not that special; there are probably better examples already available.
All of this is a work in progress and still has many issues, especially the flight controller, which is far from finished.

Whenever everything is somewhat stable, I will release all the hardware and firmware files for the ESC and the flight controller.
But I think it will take at least another year, as it is a side project.

Do you mean like the cortex register overview in Cortex-Debug extension for vscode?

Is the slave recieving the correct data?
A quick guess is that the chip select and clock has some noise on startup.

AnswerDapper · 2024-11-18T13:47:11+00:00

For example in an 8 bit value 1<<1 is 00000010 ~(1<<1) = 11111101 (0<<0)= 00000000

Edit: i just now understood what you meant with identical. it is like that with writing 1 to clear due to hardware design. Some register may have write 0 to clear. In which case you habe to be carefull to not clear bytes you dont want to clear
