3 years ago Hello there, and thank you. I hope this message translates okay. If anything is confusing, please feel free to ask again.
Your Uno can actually handle up to 9 drives. The "analog" pins also act as digital pins. But this is still not 30 drives.
First, you should know that MIDI files can only have 16 channels. So with 30 drives, some of the drives may need to play the same notes at the same time. Or, you may have to get creative about splitting up the 16 channels into 30 different parts.
You have two options for connecting 30 drives:
- You could get 4 additional Unos (9 drives per Uno would give you up to 36 drives). You would need to update these lines in MoppyConfig.h to give each Uno a unique
DEVICE_ADDRESS, and specify the number of drives withMAX_SUB_ADDRESS. Then in the MoppyControlGUI, you would add 3 additional Mappers on the lower part of the screen, and change the DeviceAddress for each Uno. - Alternatively, you could get some bit-shifters (translated as "manifolds" I think) and connect them to your one Uno. You'll need to comment out
INSTRUMENT_FLOPPIESand uncommentINSTRUMENT_SHIFTED_FLOPPIESon these lines. And you'll still need to updateMAX_SUB_ADDRESSto however many disk drives you have.
I have successfully used method 2 for eight drives, but only on an ESP8266. I don't know if an Uno's clock speed will be enough to handle the bit-shifters.
Good luck! Let me know if you have any more questions.

finally it worked: D without help it would take a lot more time, thank you very much: D does anyone know any test sounds for all channels? regards
Hello, at the outset, I greet the author, it is a very good job. I'm after connecting the first drive for the first time. I would like to expand my project to 30 disks. Here are my questions. my UNO will handle physically without manifolds 6. Buy an additional 4 UNO or some manifold? What about additional UNOs and the mapping of their stations? Are there any examples that can be modeled on to ensure that the sound is as well separated as possible? Sorry for my english, it is from google uncle. I greet you all warmly :)
