Hi,

I want create a tab with two dimensions ( int tabvalLumiPosLdr1 [180][180]), but when i compile my
code i get this error : error: size of array 'tabvalLumiPosLdr1' is too large.

I did't find any answer in internet .

Thx for your answers and help.

Do you have 64800 bytes of RAM available to put your array into?

Your array would need 64800 bytes.

But the limit with all 8-bit Atmegas is 32 KB maximum array size.

Besides of that: Which 8-bit Arduino provides 64800 bytes of RAM?

'1284P has 16K SRAM, I have used it to make 14500 byte arrays to pull data from really quickly, updating a bank of 45 shift registers at 20KHz rate. Love that chip!
I offer boards in several form factors, this one for example is like a Duemilanove (using FTDI chip for USB, vs 16U2 for a Uno).
