Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
ByteConvert
What's about ?
Have you ever wanted to transmit int,short,long,double or any other numeric type over I2C,SPI,serial or other protocol or bus, but you converted variable to string to be able to transmit it char by char. This library enables you to convert any numeric value to bytes or other way around and you can also print array of bytes.
What you need to consider, when you are using this library
When you are using this library, you need to consider variable byte size, because if you are using different platforms, then there may be some errors, because int on platform 1 has 4 bytes and int on platform 2 may has 2 bytes.
Examples
Convert numeric variable for eg. int,short,float,double to array of bytes.
int somevar = 5;
size_t blk_size = 0;
uint8_t *block = ByteConvert::varToArray<int>(blk_size,somevar);
// Use array
delete block; // Don't forget to free memory, when you don't need array any moreConvert array of bytes to numeric variable.
uint8_t *block; // Predefined byte array with size of int
int somevar = ByteConvert::arrayToVar<int>(block);
// Use block & somevar
delete block; // Don't forget to free memory, when you don't need array any more
// Use somevarConvert array of bytes to string of hex characters
size_t blk_size; // Predefined size of byte array
uint8_t *block; // Predefined byte array with size of int
String somevar = ByteConvert::arrayToString(blk_size,block);
// Use block & somevar
delete block; // Don't forget to free memory, when you don't need array any more
// Use somevarConvert string of hex characters to array of bytes
String somevar = ""; // Predefined string
size_t blk_size = 0;
uint8_t *block = ByteConvert::stringToArray(blk_size,somevar);
// Use block
delete block; // Don't forget to free memory, when you don't need array any more
