Write and read binary bytes
Java: Use the byte-oriented Files methods when text encoding should not be involved.
Java✓ Tested
Write and read binary bytes
Round-trip a byte buffer through a C binary file.
C✓ Tested
Write and read typed binary fields
Java: Data streams use a matching write/read order and fixed encodings for Java primitive values.
Java✓ Tested
Assemble a big-endian 16-bit value
Arduino / C: Cast to an unsigned 16-bit type before shifting the high byte.
Arduino / C✓ Tested
Assign a bit from a Boolean state
Arduino / C: bitWrite accepts a bit position and a zero or nonzero value.
Arduino / C✓ Tested
Calculate a CRC-8 over a byte sequence
Arduino / C: This implementation uses polynomial 0x07, initial zero, and no reflection.
Arduino / C✓ Tested
Calculate a simple packet XOR checksum
Arduino / C: XOR all payload bytes to produce a basic error-detection byte.
Arduino / C✓ Tested
Clear a flag without affecting neighboring bits
Arduino / C: bitClear resets only the selected bit.
Arduino / C✓ Tested
Convert ASCII text to lowercase safely
C: Cast to unsigned char before calling ctype functions on a possibly signed char.
C✓ Tested
Convert bytes to Base64 and back
C#: Encode text to UTF-8 before converting it to a Base64 representation.
C#✓ Tested
Copy a file without replacing an existing destination
Java: Files.copy fails if the destination already exists unless replacement is explicitly enabled.
Java✓ Tested
Create and clean up a temporary file
Java: Create a unique file and remove it in finally even when the operation fails.
