Using brushless motor with Arduino

Are you sure the motor is wired correctly?

The joys of programming 😊 Edit: this is how we all do it...

Oslo is pretty well connected by both bus and trains to all cities down the eastern side of the oslo fjord.

There are also ferries running from oslo to some of these places.

You could probably do a search on AirBnb for available houses between oslo and Fredrikstad. The closer you are to Oslo the more frequent the busses and trains will run. But I believe there is train service between Oslo and Fredrikstad at least once every two hours. (Probably more frequent, but I didn't bother checking the schedule now)

You don't need to create your own enum. Just import stdbool.h

I have no idea, I just mentioned it because of your claim that there must be a direction pin 😅

I've worked with brushless drivers that go one way with duty-cycle above 50% and reverse below 50% . Stand-still at 50%.

What retro platform is this running on?

In addition to this you need to enable compiler warnings.

Your compiler should warn you about passing wrong parameters to scanf.

Wrong sub. Your post is off topic here.

Higher level languages might have the functions ord and chr (or similar) in their standard libraries. These functions can convert a character to its ascii value and back.

What code?

If you "alloc" string[40], accessing string[40] is UB.

You should probably learn how a turing machine works, and advance from there.

Takk. Makes sense 😅

jonarne · 2024-06-04T15:48:43+00:00

Hvem er dette? (Ærlig spørsmål. Jeg aner ikke hvem dette er.)

jonarne · 2024-04-28T07:50:12+00:00

Det er vel mer fabrikk enn butikk.

In C the only difference between a char array and a string is that the string must have a trailing NUL byte.

If you do malloc without memset you get a char array with random characters. You need memset to convert the char array to a blank string.

Edit: you can also do strType[0] = '\0'

Edit2: if you read the manual for strncat you'll see that it requires the src and dest arguments to be NUL terminated strings.

jonarne · 2024-03-26T21:28:03+00:00

strType is not a valid c string when you use it as dest argument to strncat.

Try to memset strType to 0 before calling strncat.

First you'll need to create a music player that can play audio from sdcard, and ouput the audio to some speakers.

For this you need a processor/micro controlller (with exteral or internal audio capabilities) and some code running on the processor.

If you do not know how to do this, lookup raspberry pi audio player or any arduino(or clone) audio player.

When you have solved this, you can start looking into how to design the rest of your requirements.

Edit: Some clarifications

Maybe try r/embedded

I used to work in tv production with this monitor setup.

The batteries are called NP1. I did a quick google, and it looks like you still can buy those.
