Arduino / CSerial protocols

Read serial text up to a delimiter

Arduino / C: readBytesUntil excludes the delimiter and does not add a null terminator.

Arduino / C✓ Tested
RustNumbers & durations

Reject a narrowing integer conversion

Reject a narrowing integer conversion in a complete Rust program using the standard library.

Rust✓ Tested
Arduino / CText & bounded buffers

Reject an integer with trailing characters

Arduino / C: strtol exposes an end pointer so a parser can require the entire token.

Arduino / C✓ Tested
Arduino / CEEPROM & program memory

Reject an unsupported settings version

Arduino / C: A version byte lets firmware fall back when stored settings use another format.

Arduino / C✓ Tested
Arduino / CArrays & embedded state

Reject insertion when a fixed queue is full

Arduino / C: Track a count separately from circular read and write positions.

Arduino / C✓ Tested
Arduino / CSensor calculations

Reject one outlier with a median-of-three filter

Arduino / C: Sorting three values leaves the median in the middle.

Arduino / C✓ Tested
ReactState & reducers

Remove an item with filter

Remove an item with filter with a small React component and explicit browser behavior.

Repeat a serial message three times

Arduino / C: Repeat a serial message three times on an Uno with the Serial Monitor set to 9600 baud.

Arduino / C✓ Tested
Arduino / CSensor calculations

Represent a decimal quantity with a scaled integer

Arduino / C: Integer hundredths avoid floating-point storage for fixed-precision values.

Arduino / C✓ Tested
Arduino / CGetting Started

Represent an enabled state

Arduino / C: Represent an enabled state on an Uno with the Serial Monitor set to 9600 baud.

Arduino / C✓ Tested
Arduino / CBinary values & packets

Require every bit in a mask

Arduino / C: Masking followed by equality tests whether all required flags are set.
