Function isPdoMappingEntry

Checks if a string is a valid representation of a CANopen PDO mapping entry.

A valid entry is a 32-bit hexadecimal value representing:

• Index (16 bits)
• Subindex (8 bits)
• Bit Length (8 bits)

It accepts formats with or without the '0x' prefix (e.g., "0x60400010" or "60400010").

Returns

true if the string follows the PDO mapping entry hex format, false otherwise.

Example

isPdoMappingEntry('0x60400010'); // true
isPdoMappingEntry('60400010');   // true
isPdoMappingEntry('invalid');    // false
