Hello,
I am doing a Led Matrix project and I want to dynamically allocate two dimensional array based on the number of digit I use.
I found a code on the internet that uses Malloc function to make this, but It did not work. I know that the issue in the code because it works fine when i allocate the array fixed.
Can u help?
Have you set your heap to be large enough? This is done in the linker file.

gahelton So let's see, you have this huge pile of RAM that you want to dynamically take a piece of, then return to the "OS" when you're done ? Sounds interesting. How much RAM do you have, and how much do you need to dynamically allocate ? With all of these multiple threads running, how can you be sure that you have enough ? < Can you see my tongue in cheek ? >

mmostafa It works fine when expanding the heap size. Thanks of the help
