Question

what is unsigned char in java?

Answer 1

Java Byte. The Java byte data type is 8 bits long, however it is a signed data type, not unsigned. The range of the byte is from 127 to -128. This differs from the Arduino byte data type which is 8 bits long and unsigned with a range from 0 to 255 (same as a C unsigned char)
