I2C Programming
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

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.
