// Line 78 & 79: #define can't start with numbers so 4_1IN_DATA
// won't work. It has been temporarily changed to IN_DATA. Will
// come back to deal with this later.
//
// Some functions names have been changed to clarify understanding
// function purpose. For example SPI_byte and SPI_bytes is now
// COG_sendbyte and COG_sendarray. This the format of naming
// functions: module_action. In this case the data is for the COG
// so the module is the COG and the action is to send either a
// byte or an array.
//
// I will apply this format to startup_cog and change it to
// COG_int and so on.
//
// I fixed the spi_sendarray to accept and array and not a uint64_t.
// I can explain this to you later.
// I also added the COG_busy function to check if the COG is... well...
// buy...
//
// Most of the other changes are small. I will continue to work on it
// after I get some food =P
// Also the code compiles now without errors ;)
