How To Stop The Run Madden 12?

Can anybody help me with this c code so it can run a stepper motor?

• The code below should be able to run a stepper motor in forward steps, reverse steps and forward 360 degrees. I also don't know how to code the send serial part of it. I'm really stuck on this. // Turn-table.cpp : main project file. #include "stdio.h" #include "reg51.h" #pragma SMALL DB OE void stop(); void forward_step(); void reverse_step(); void forward_cont(); //void sendCharacter(char h); unsigned char ReceiveSerial() { unsigned char c; TMOD = 0x20; //configure timer for the correct baud rate// TH1 = 0xe6; //1200 bps for 12 MHz clock// TCON = 0x00; //set timer to not running// SCON = 0x50; //set serial IO to receive and normal mode// TR1 = 1; //start timer to receive// while((SCON & 0x01) == 0); //wait for receive data// c = SBUF; //returns a character// return c; } void SendSerial(unsigned char c){ //initialise... set values for TMOD, TH1 and TCON// //set the Tx interupt in SCON to indicate sending data// //start timer// //write character to SBUF// //wait for completion of sent data// TI = 1; TR1 = 1; void sendCharacter(char) //sendCharacter(myChar); } //void sendChacracter(char h){ // p3.0 = h; //} drive_stepper(stop, forward_step, reverse_step, forward_cont) { static byte stepper_state = 0; unsigned byte i; void main(void){ //char s, f, r, fc; int s, f, r, fc; while(1){ //Use ReceiveSerial to read in a character// //Depending on character, make the motor move left or right// for(i=0;i<1000;i++) delay_ms(20); if (s == 0) stop(); else if (f == 1) forward_step(); else if (r == 2) reverse_step(); else if (fc == 3) forward_cont(); else stop() end if; } } void stop () { //assign all ports zero printf("stop"); } void forward_step() { //for loop for certain amount of time //assign a forward hex number on both ports printf("forward step"); } void reverse_step() { // assign reverse hex number on both ports printf("reverse step"); } void forward_cont() { //while!=button being pressed interrupts //assign full hex number to both ports 0xFFFF printf("forward cont"); }

• Answer:

  0 1 1 0 6 0 0 1 0 4 0 0 1 1 12 0 0 0 1 8 1 0 0 1 9 so that u make a lookup table that have the numbers {1,3,2,6,4,12,8,9} so if the porgram scan them from the right to the left the motor will be run and if the program scans them from the left to the right the motor will reverse i modified ur program assuming u r going to use portb try this code: #include "stdio.h" #include "reg51.h" #pragma SMALL DB OE void stop(); void forward_step(); void reverse_step(); void forward_cont(); //void sendCharacter(char h); unsigned int truth_table[]={1,3,2,6,4,12,8,9}; // the truth table of the stepper motor unsigned int truth_table_counter=1; // this will count the steps of the motor . . . . . . . . . . void stop () { //assign all ports zero printf("stop"); } void forward_step() { //for loop for certain amount of time //assign a forward hex number on both ports printf("forward step"); } void reverse_step() { // assign reverse hex number on both ports printf("reverse step"); } void forward_cont() { //while!=button being pressed interrupts //assign full hex number to both ports 0xFFFF printf("forward cont"); } p.s. replace the dots with the rest of the code
