This is a very simple chase lighting program for the Elf Membership Card . It is mainly used for testing my RaspiElf tools. I use the A18 cross assembler (see below how to get and build the assembler): | ||||||||

The cross assembler generates two output files: the object file (Intel hex file chase.hex) and the listing file (chase.lst). You can load the program into the Elf Membership Card the traditional way by setting the switches. Or upload it with the RaspiElf bin2elf tool. But for this we need a binary file first. A handy tool is Jacques Pelletier's Hex2bin (see below how to get and install Hex2bin). | ||||||||

How to build Hex2bin for the Raspberry PiHex2bin is a Intel Hex or Motorola Hex file converter. You can download the tarball from Sourceforge http://hex2bin.sourceforge.net/.
