I2C Programming

Archiver

Hi,

I'm writing up a Stamp program for controlling a Programmable Clock
Generator. In the message format of the I2COUT of the stamp, is the
SlaveID always in a hexadecimal format?

For example:

I2COUT 0,$A0, 5,[noparse][[/noparse]100]

1)Does $A mean that it is in a HEX format?
2)Is 5 in ASCII? What do I need to do access the address in a HEX
format?
3)What if I need to write the value 100 in a Hex format? [noparse][[/noparse]HEX 100]??

Looking forward to hearing from somebody!

Thanks
Denush

You can use any numeric format you choose with any BASIC Stamp instruction.
If no indicator is present, the value is assumed decimal. A leading $
indicates hexadecimal and a leading % indicates binary.

100 [noparse][[/noparse]decimal] = $64 [noparse][[/noparse]hex] = %1100100 [noparse][[/noparse]binary]

Hint: The Windows calculator -- in Scientific view -- lets you convert
between formats easily.
