А что вам непонятно? 0 перед числом говорит, что это число — в восьмеричной системе счисления, а там, как известно, нет цифры 8.
0x перед числом — говорит, что это число в шестнадцатеричной системе счисления.
Короче — уберите 0 спереди у чисел 0783 и 0473 — они там не нужны.
Hi.
I came across a strange errormessage and it might be a bug in the 1.0.5 version of the arduino software.
The part of the code that gets the error looks like this:
» if (i == 01) catchd01 = t;
if (i == 02) catchd02 = t;
if (i == 03) catchd03 = t;
if (i == 04) catchd04 = t;
if (i == 05) catchd05 = t;
if (i == 06) catchd06 = t;
if (i == 07) catchd07 = t;
if (i == 08) catchd08 = t;
if (i == 09) catchd09 = t;
«
And the compiler only complains on the last 2 lines.
error: invalid digit «8» in octal constant
error: invalid digit «9» in octal constant
So, whats wrong? it compiles good if all zeros are removed from the i == part.
But shouldnt it complain on all 9 lines if its the zero that is the problem.. why just 8 and 9?
because the compiler thinks you are using OCTAL number, and octal number
goes from 0 to 7.
Also, if this was a bug, was a COMPILER fault, you should had ask to
avr-gcc’s folks.

Reply to this email directly or view it on GitHubhttps://github.com//issues/1490
.
A constant number starting with «0» is interpreted as octal by the compiler, you must write «8» instead of «08».
BTW programming questions should be addressed to the forum.
