Need help with Variables ?

[David Bryan]

We wrote a routine in user_routines_fast.c and user_routines.c for autonomous.

Here are the definitions in
user_routines_fast.c:

long Left_Encoder_Count = 0;
long Right_Encoder_Count = 0;
int lh_encoder_max;
unsigned int rh_encoder_max;
long int rh_en_count;
long int lh_en_count;
float target_ratio;
float actual_ratio;
unsigned char autorun_status = 1;
#define lh_en Left_Encoder_Count;
#define rh_en Right_Encoder_Count;
#define pwm1_lh pwm01
#define pwm2_rh pwm02
int pw2_rhpos;
int pw2_rhneg;
/* delete all of thse ---- float lh_30turnfactor ; */
int onecnt = 0; /* one tenth of a second counter */
int rhcnt = 0;
int lhcnt = 0;
int rhcnt1000 = 0;
float actual_factor = 0;
float rh_adjust_factor = 0;
int rh_speed_var = 220;

these are the variables in
user_routines.c

int pwadd = 0;
int pwadd2 = 0;
char heat = 'c';
unsigned float pwadd3 = 300;
int pwadd4 = 0;
int p1xvar2;
int p1yvar2;
int p1xcoef = 150; /*max no =100 50 takes 14 scans to catch up*/
int p1ycoef = 150; /*con 100 takes 6 scans to catch up 150 = 5 SCANS*/
int p1yfl; /* p1x filter */
int p1xfl; /* p1y filter */

float lh_30turnfactor ;
int onecnt = 0; /* one tenth of a second counter */
int rhcnt = 0;
int lhcnt = 0;
int rhcnt1000 = 0;



float actual_factor = 0;
float rh_adjust_factor = 0;
int rh_speed_var = 220;

float pwadd5 = 1;
int pwadd6 = 0;
rom const char *StrPtr = "Hello world!";
/* int x = 15;
*int y = 0x50;
*long z = 0xdeadface; */
extern long Left_Encoder_Count; /* tm 226 see these in fast.c*/
#define lenco Left_Encoder_Count

I thought that the variables used in user_routines_fast.c could be defined as "extern"
also for use in user_routines.c. At least it did work for these variables:

user_routines_fast.c:

long Left_Encoder_Count = 0;
long Right_Encoder_Count = 0;

user_routines.c:
extern long Left_Encoder_Count; /* tm 226 see these in fast.c*/

extern long Right_Encoder_Count; /* tm 226 see these in fast.c*/

When we compile we get an error message as shown below:
if (autorun_status == 1)
/* State 1 - Initialize for straight movement for seven feet fast 5.0 --*/

{
pwm1_lh = 127; /* Stop left motor */
pwm2_rh = 127; /* Stop right motor */

rh_en = 0; /* Reset actual encoder count we get an error on this line!!!*/
lh_en = 0; /* Reset actual encoder count */
rh_en_count = 0; /* Reset saved encoder count */
lh_en_count = 0; /* Reset saved encoder count */

rh_encoder_max = 771; /* Initialize max encoder counts for step 1 */
lh_encoder_max = 771; /* Initialize max encoder counts for step 1 */
target_ratio = 1.0; /* 1.0 straight, 1.1 turns left (more rh) .9 turns right */

pwm1_lh = 180; /* Set inital left motor speed */
pwm2_rh = 180; /* Set initial right motor speed */

autorun_status = 2; } /* or send to #3 and try that */
/* State 2 - Maintain target ratio for seven feet */

Sorry, but we cannot see anything wrong with the syntax of
rh_en = 0;
??????

I think we need help in defining variables used in user_routines_fast.c versus those used in user_routines.c.

Thanks to anyone who can help!!
