hello,
i have a c question :
i have a global array : unsigned char test[2][2];
each time a certain button is pressed, i want to reset my array to the default array
{{1,2},{2,2}}
(this is just a 2*2 example, the array in my code is much bigger).
int this case the following line doesn’t work :
test = {{1,2},{2,2}};
i don’t want to use a loop for this !
do i have to use pointers ?
thanx
jeb
I’ve read something about sdcc wanting brackets around every entry, maybe try this:
test = {{{1},{2}},{{2},{2}}};
Wow that’s ugly!
hello,
no the brackets solution doesn’t work !
the problem is maybe that i want to redefine the values of an array which has already been defined.
should i use pointers ?
for example if i have a global variable :
//// unsigned char test [3];
the use of this, in a function :
//// test = {8, 8, 8};
gives :
syntax error: token -> ‘{’ ; column 9
thanx in advance!
Hello,
I think that this way of intializing arrays is only valid when it’s used while defining the variable. I don’t think it’s allowed to be used as this in the body of a function.
You could indeed use a pointer instead, have a collection of the constant tables as you shown and have the pointer to point on one of the constant tables.
Othewise, you can also define constant tables and use a memcpy like function to copy the constant table within your array.
Best regards,

I had a feeling that was it, but I didn’t have the confidence to say it heheheh
Hey jeb what are you putting in this array? There might be a quick way, depending on what is going in there…
AFAIK, You could always cheat…
test[0] = {1,2};
test[1] = {2,2};
;D
If that compiles with SDCC PIC16 port, I’ll give you a lollypop.
