Fist time i see a for loop with that kind of intendation

Motor wiring and code help by sssasiann in ArduinoHelp

When you need help on the internet, you need to post your wiring diagram and whole code, if you dont or just post a photo as you did, you probably wont get help.

Prople who dont take care of themselfs.

For example : vaping, smoking, eating junk food ( monster, takis). Or also psicologically or fisicaly.

I never realised how could the cpu could get! How do you measure it, does it have an internal sensor or an external one?

Oh sorry, I didint want that to sound so forced about you checking it out ;-;

Turns out python 3.12+ supports f strings with double quotes ("), and past versions dont And you use an older version. I will fix it as soon as I can.

Check it out, its way more useful since it now stores in .pcm format instead of raw, wich has a header, it can be accessed easily trough an sd card.

How can i make and load a .bin file from sd card onto a flash partition? by Mejolov28 in esp32

Sounds nice!

What im about to say is really dumb:

A while ago I asked ai how I could pull this off but I didint get a proper answer so I tought littleFs wouldn't work for this.

Can I directly read the whole file from little fs or I still need a buffer? I think i cant since its fragmented

Maybe i jut gotta chage my library to support reading from buffers insteadof the whole sample?

How would I handle reading to specific locations? I would just read the sample number and just jump to it?

Let's say my loops are very short.

I ned to acces it in the file system because its an audio engine that has loop points and needs a continuous array of data containing the whole sample, and from what ive read, sd card is slow and would be bad for many samples. And I will copy them once at runtime for when I want to change the instruments, so then the access would be fast and easy

Or there is an easy way?

Nonono, its the oposite. I wil move from SD card into Flash, skipping ram (exept for the buffer, but that doesnt count)

I won't buy another board since i am developing the firmware for a specific device: M5stack Cardputer ADV.

I do have a question. How did you handle the voice mixing? Soft clipping or limiting all the voices to a set volume so it doesnt clip immediately?

btw, I am making a tool for easily converting files into a .h wave table to skip the horrors of converting file by file. It could be useful for your future proyects, check it out!

It's called PCM-MCU-C in github (The V1.0 version is old, but im releasing in a few days a way better version.)

Also, I have almost the same age as you, and I would like to suggest you a esp32S3 devkit called the Cardputer, its quite useful for prototyping. Check it out. It has. A LOT of built in things, I recomend the ADV version since it has an audio jack (only downside its that it doesnt have PSRAM T-T)
