Registerer is a Hex/Bin/Dec converter aiming embedded developers which have to deal with hardware registers a lot. It's developed using the Qt Framework.

Usage: (is pretty simple)

Enter a number in the number field and press enter. Prefix the number with 0b in case you enter a binary or 0x if you enter a hex number. CTRL-d (or d[isplay] button) will toggle through dec-hex-bin.

You may show a bit position pointer by entering the position into the pos field. CTRL-t (or the t[oggle] button) will toggle the bit at the position pointed by 'Pos'.


  • Convert binary 10101010 to hex:

    Enter 0b10101010 into 'Number' and press CTRL-d twice.

  • Create a hex number with bit 31 is one:

    Enter 0x0 into 'Number' to indicate you want a hex. Enter 31 into 'Pos' and press CTRL-t (or the t button).

  • Create a binary number with bit 15 is one:

    Enter 0b0 into 'Number' to indicate you want a binary. Enter 15 into 'Pos' and press CTRL-t (or the t button).

You can’t perform that action at this time.
