Hi All,
I'm trying to use StreamDevice to talk to a device that is almost, but not quite, giving me data that the format converters (as I understand them) can convert.
It’s an ASCII representation of the IEEE 32 bit floating point format, e.g. the raw data for a value of 28.0 is
0x34 0x31 0x45 0x30 0x30 0x30 0x30 0x30
Which is the ASCII code for
41E00000
I think that if the raw data were 0x41E00000, %R would be able to convert it. And if the raw data were
0x32 0x38 0x2E 0x30 (ASCII for 28.0)
then %f would be able to convert it.
Before I start writing calc records to convert the 32 bits to a float value, I figured I'd ask if someone had a less brute-force approach. Maybe a StreamDevice format converter trick I don't know about?
Thanks,
Garth
