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 more

Convert 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 somevar

Convert 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 somevar

Convert 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
