If I use one variable float or one Interrupt fonction the next error appears: Error L107 Adress space overflow Space: Data Segement: _Data_Group_ Lengh: 002AH Do you know why??
Maybe. Rule one. Start with the SMALL model. Rule Two. Give every variable a memory space storage qualifier. Place only your most critically fast variables in data. Allocate the rest in idata. Large arrays or structures go in xdata if you have external data. Rule Three. Turn on optimization, I use OT(9, size) even during debug.
