Read and total a flash lookup table
Arduino / C: Array size can be computed at compile time even for a flash-resident table.
Arduino / C✓ Tested
Reject an unsupported settings version
Arduino / C: A version byte lets firmware fall back when stored settings use another format.
Arduino / C✓ Tested
Store a bounded null-terminated text setting
Arduino / C: Write a fixed buffer and explicitly terminate the retrieved copy.
Arduino / C✓ Tested
Store a compact configuration record
Arduino / C: Save a struct and retrieve it with the same field layout.
Arduino / C✓ Tested
Store a variable-length payload after a structure header
C: A flexible array member lets one allocation hold metadata and trailing bytes.
C✓ Tested
Store and retrieve a multibyte integer
Arduino / C: put and get copy the bytes of a typed value.
Arduino / C✓ Tested
Swap owned buffers by swapping their pointers
C: Pointer swaps avoid copying the underlying data.
C✓ Tested
Validate a small stored payload with a checksum
Arduino / C: Store a checksum with the payload and reject a changed byte.
Arduino / C✓ Tested
Allocate a zeroed array
Check calloc, use the allocation, and release it in C.
C✓ Tested
Format a decimal value
Print two fractional digits with C printf.
C✓ Tested
Hash a file without reading it all at once
Python: Feed fixed-size binary chunks into SHA-256 for files larger than memory.
Python✓ Tested
