Common Questions & Answers } set_tris_b(ALL_IN); i = PORTB; // i now contains the portb value. Remember when using the #BYTE, the created variable is treated like memory. You must maintain the tri-state control registers yourself via the SET_TRIS_X function. Following is an example of placing a structure on an I/O port: struct port_b_layout {int data : 4; int rw : 1; int cd : 1; int enable : 1; int reset : 1; }; struct port_b_layout port_b; #byte port_b = 6 struct port_b_layout const INIT_1 = {0, 1,1, 1,1 }; struct port_b_layout const INIT_2 = {3, 1,1, 1,0 }; struct port_b_layout const INIT_3 = {0, 0,0, 0,0 }; struct port_b_layout const FOR_SEND = {0,0,0, 0,0 }; // All outputs struct port_b_layout const FOR_READ = {15,0,0, 0,0 }; // Data is an input main() { int x; set_tris_b((int)FOR_SEND); port_b = INIT_1; delay_us(25); // The constant // structure is // treated like // a byte and // is used to // set the data // direction } port_b = INIT_2; port_b = INIT_3; set_tris_b((int)FOR_READ); port_b.rw=0; port_b.cd=1; port_b.enable=0; x = port_b.data; port_b.enable=0 // These constant structures delay_us(25); // are used to set all fields // on the port with a single // command // Here the individual // fields are accessed // independently. How does the compiler determine TRUE and FALSE on expressions? When relational expressions are assigned to variables, the result is always 0 or 1. For example: bytevar = 5>0; //bytevar will be 1 bytevar = 0>5; //bytevar will be 0 The same is true when relational operators are used in expressions. 359
