We have a short program in the spark core and we are using a char array to display it in an lcd display.
When we increase the size of the array, the core doesnt flash. It looks like there is a communication error and the core doesn´t see it is being flashed (USB). We think it is because of the small size of the internal memory.
I want to store the array variable in the external memory but i don’t know how, does anybody have a basic program showing how to use it please?? thax
