... the structure suggested for the Arduino program said,
"uint32_t syncPattern; / /4 bytes with a fixed value, e.g. 0xa5a5, marks the beginning of a header",
Ok, so we still have two options, depending on if its a big-endian or little-endian CPU.
The two equivalent byte streams in Euphoria would be ...
constant sync_BE = {#00, #00, #A5, #A5} constant sync_LE = {#A5, #A5, #00, #00} -- Typically Intel machines.
Thanks Derek, I find things that say it's little-endian, but I'll have to test it, as I don't understand why you have the #00 pairs following the #A5 pairs rather than interspersed:
constant sync_LE = {#A5, #00, #A5 ,#00}
And thanks for subtly reminding me to put all code in code format, I see that it does help, even for non Eu code!
