8051

Assembly sources

Fast 24 bit binary to 8 digit packed BCD conversion
This routine can be extended to any length. It does not use divide routines but shifts the bit pattern one bit at a time while converting the result to BCD nibbles. This code example is optimized for the 8051 but does not use any special decimal arithmetic instructions. The algorithm is completely documented and can be ported to other micros.
Free to use if the author names are kept in the source code.
