## NAME

hackrf\_debug - register manipultion tool

## DESCRIPTION

### Usage:

**-h**, **--help**: this help

**-n**, **--register** \<n\>: set register number for read/write operations

**-r**, **--read**: read register specified by last **-n** argument, or all registers

**-w**, **--write** \<v\>: write register specified by last **-n** argument with value \<v\>

**-c**, **--config**: print SI5351C multisynth configuration information

**-d**, **--device** \<s\>: specify a particular device by serial number

**-m**, **--max2837**: target MAX2837

**-s**, **--si5351c**: target SI5351C

**-f**, **--rffc5072**: target RFFC5072

**-u**, **--ui** \<1/0\>: enable/disable UI

## EXAMPLES

- hackrf\_debug --si5351c -n 0 -r

  \# reads from si5351c register 0

- hackrf\_debug --si5351c -c

  \# displays si5351c multisynth configuration

- hackrf\_debug --rffc5072 -r

  \# reads all rffc5072 registers

-

  hackrf\_debug --max2837 -n 10 -w 22 # writes max2837 register 10 with 22 decimal
