Hello, I'm pretty new with HT-Soft Pic C Compiler and I don't know how to make it position some variables at a fixed address. For example, if I have a vector MyStruct vector[VECTOR_SIZE], when I write vector[counter], I observed that this takes a big amount of code space and I would like to write something like this MyStruct vector[VECTOR_SIZE] at vector_address; Vector_adress + 8*counter = value; Is this possible ?
