PIC18F47J53 big-endian float IEEE754/float conversion
PostPosted: Thu Apr 27, 2023 6:42 am     Reply with quote
Hi,

I'm using a PIC18F47J53 , CCS C compiler version 5.090.

A sensor provides big-endian float IEEE754 data (1 sample, 4 bytes).

I need to convert them in float type variables.

How can I do this ?

Regards,

Marco

Look in the drivers directory. IEEEfloat.c
Provides code to convert a four byte value stored in an int32 to PIC format
and to IEEE format. Also a union 'joiner' to give the conversion between
a value in int32 and float.
