How to use Convert BCD to Hex
- 1. Paste the BCD nibbles. Enter binary coded decimal groups, four bits per decimal digit, like 0110 0101 into the input pane. Each group must be 0000 through 1001 to be a valid digit.
- 2. Decimal digits, then hex. The tool reads each nibble as one decimal digit, assembles the digits into a number, and re-expresses that number in base 16, which is how 0110 0101 (65) becomes 41.
- 3. Copy the hex value. Copy the converted result from the output pane into your driver code, register documentation or debugging notes.
When to use Convert BCD to Hex
Convert BCD to Hex decodes the packed decimal format used by real-time clocks, meters and old instrumentation into ordinary hexadecimal. Hardware that stores 65 as nibbles 6 and 5 confuses anyone reading raw registers, and this tool untangles the two representations in one step.
- Decoding RTC chip registers. DS1307-style clock chips store seconds, minutes and hours in BCD. Paste the bits from your I2C dump to see the true values and the hex your firmware should expect.
- Reading utility meter output. Energy meters and industrial counters often transmit readings as packed BCD. Convert a captured frame to verify your parser decodes the same consumption figure the display shows.
- Porting legacy mainframe data. Files exported from COBOL systems contain zoned and packed decimal fields. Converting sample nibble sequences helps you confirm field boundaries before writing the migration script.
- Debugging a BCD arithmetic routine. Your emulator implements the decimal adjust instruction and something is off. Convert intermediate BCD states to hex to compare against a reference CPU trace step by step.
