Sir
i tried to compile (Bleep drum V12 download from Dr. bleep website) attached zip there are many warnings
also txt file attached Please guide me to solve the problems.
thanks

BLEEP_DRUM_12.zip (22.1 KB)

warnings.txt (931 KB)

I (and many others) will not download and unzip zip files.

The warnings are because you are trying to put values greater than 127 into a char data type. The char data type is signed 8 bit so can contain only values from -128 to 127. I only looked at part of the warnings ile because it is too large a file to view on my device.

The program that you are trying to compile is probably not written for the processor that you are trying to compile it for.

You don't have any actual errors in the sketch, just warnings. The problem is at the very end, which would indicate there was a problem trying to upload the sketch to the arduino, not a problem with the sketch itself. Did you have the correct board selected (you are compiling for an UNO), and was the correct port selected?

Sketch uses 30308 bytes (93%) of program storage space. Maximum is 32256 bytes.
Global variables use 1665 bytes (81%) of dynamic memory, leaving 383 bytes for local variables. Maximum is 2048 bytes.
Low memory available, stability problems may occur.
An error occurred while uploading the sketch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Warnings should not be ignored. What might seem like a simple warning could be a defect waiting to happen.

I'm not going to take the time to try and understand the entire sketch. The tables causing the errors are declared as char instead of byte, and in another portion of the sketch 127 is being subtracted from the value, so not really sure what is going on. The sketch is 2 years old, and the tables are 7 months old, so I am going to assume that at some point this actually worked and the author was willing to ignore the warnings.
