Hey, I am trying to do a simple assignment where I am assigning one long to another. The left side of the equal sign is an element in a structure that is part of a union including other structures and a buffer array. It is referenced using a pointer to the union. The right side of the equal sign has an element of a structure that is also part of a union including a buffer array. command_data->status_struct.baseline = data_logger_status_0.status_data.baseline; It compiles fine, but when I run it, it cause the program to crash in a totally unrelated area of the code. In fact the function in which this snippet resides is not even called anywhere in the code for now. Does the C51 compiler have problems with longs?
I put code in vector space. Of course, I avoid the addresses that I need for interrupt vectors for hardware that I actually use. But the rest of the code memory in the first page is fair game for other purposes. Does Cypress devices have some special restriction in this regard? It would be a good thing to remember if I ever have to use one in the future.
