Boards including the Uno, Duemilanove, Diecimila, Nano, and Mega have a chip to convert the hardware serial port on the Arduino chip to Universal Serial Bus (USB) for connection to the hardware serial port. Other boards, such as the Mini, Pro, Pro Mini, Boarduino, Sanguino, and Modern ...
dprint(x); - Writes to the serial port something like: # x: 123 dshow("Some string"); - Writes the string This is the definition: #if DEBUG == 1 #define dprint(expression) Serial.print("# "); Serial.print( #expression ); Serial.print( ": " ); Serial.println( expression ) ...

Repetier-Firmware uses a higher resolution for input and temperature and these factors convert old tables you may have into the needed value range for Repetier-Firmware. If you don’t have a matching table, you have to compute one.Looking into the datasheet gives characteristic curve 8404 for ...
Drawing an image is different and a bit complicated. As the display module is monocolour, we need to first convert our image to a format called mono color bitmap (also called black and white). In such a format, each pixel of the image is presented with either 0 or 1. The 1s represe...
representation used by the language C/C++. Actally, the original files are in ASCII format (not in binary format). If you are not using C/C++ or if you want to load the files directly to the SI4735-D60 or SI4732-A10, you must convert the values to numeric value of the hexadecimal...
