class MemTest < ArduinoPlugin
# RAD plugins are c methods, directives, external variables and assignments and calls
# that may be added to the main setup method
# function prototypes not needed since we generate them automatically
# directives, external variables and setup assignments and calls can be added rails style (not c style)
# add to directives
#plugin_directives "#define EXAMPLE 10"
# add to external variables
# external_variables "int foo, bar"
# add the following to the setup method
# add_to_setup "foo = 1";, "bar = 1;" "sub_setup();"
# one or more methods may be added and prototypes are generated automatically with rake make:upload
# test the memory on your arduino uncommenting the following:
# add_to_setup "memoryTest();"
# or adding "memoryTest()" (no semicolon) to your main sketch
int memoryTest() {
int byteCounter = 0; // initialize a counter
byte *byteArray; // create a pointer to a byte array
while ( (byteArray = (byte*) malloc (byteCounter * sizeof(byte))) != NULL ) {
byteCounter++; // if allocation was successful, then up the count for the next try
free(byteArray); // free memory after allocating it
}
free(byteArray); // also free memory after the function finishes"
return byteCounter; // send back the highest number of bytes successfully allocated
}
