What I must change on the "7 segment component code" C-program to change from common anode to common cathode.

Code: Select all

Re: change 7 seg from common anode to common cathode ??

Hello Badger

You should just have to edit this line.

Code: Select all

//display the digit
#if (%q == 1)


and set it to this

Code: Select all

//display the digit
#if (0 == 1)


It looks like the C code file has already been updated to allow for common cathode displays but the actual components have not yet been updated to reflect the C code changes.

Let me know how you get on.

Hello Benj, thanks for the tip. I want to try in next day and tell you the results.

Re: change 7 seg from common anode to common cathode ??

Hi to all, i know this is an old thread but i have a question about.


I am using single 7-seg components in my program. The device is the 18F8622

I need five single 7-seg components in my program. I am getting the error messages below when i compile to HEX.

Que_Informator.c(1740:2): error: unknown identifier 'MX_7SEG1_SEGMENT_TRIS'
Que_Informator.c(1740:2): error: invalid operand 'MX_7SEG1_SEGMENT_TRIS'
Que_Informator.c(1740:24): error: failed to generate expression
Que_Informator.c(1748:2): error: unknown identifier 'MX_7SEG1_SEGMENT_PORT'
Que_Informator.c(1748:2): error: invalid operand 'MX_7SEG1_SEGMENT_PORT'
Que_Informator.c(1748:24): error: failed to generate expression
Que_Informator.c success

failure

Return code = 1


I just realized that my program works OK if i use only three 7-seg displays but NOT if i add more than three 7-seg components.
Is there anything that i should know about and i don't ?

Regards
George

I will answer to my question above since i found out what the problem was so anybody with this issue can read this solution.

The problem was that in the "ShowDigit" custon code (right click on the 7seg component and select custon code) ,where only the port a, b ,c,d,e was defined.
For my project i have connected my fourth and fifth display to port 'f' and port 'h' which are not defined in this custom code and this is the reason of the error above.
If you want to add more than 3 single 7 seg displays to your project, you have to add the definitions for those extra displays as shown below in RED bold text:



#define MX_7SEG_SEG_PORT_%a
#define MX_7SEG_COM_PORT_%b

#ifdef MX_7SEG_SEG_PORT_0 //Segment Port Definitions
#define MX_7SEG1_SEGMENT_PORT porta

#endif

#ifdef MX_7SEG_SEG_PORT_1
#define MX_7SEG1_SEGMENT_PORT portb
#define MX_7SEG1_SEGMENT_TRIS trisb
#endif

#ifdef MX_7SEG_SEG_PORT_2
#define MX_7SEG1_SEGMENT_PORT portc
#define MX_7SEG1_SEGMENT_TRIS trisc

#ifdef MX_7SEG_COM_PORT_7

#define MX_7SEG1_COMMON_TRIS trish
#endif


//set pattern array for the display
#ifdef _BOOSTC
rom char* cSegmentArray = {%c, %d, %e, %f, %g, %h, %i, %j, %k, %l};
#endif
#ifdef HI_TECH_C
const char cSegmentArray[] = {%c, %d, %e, %f, %g, %h, %i, %j, %k, %l};
#endif

//get pattern for digit
char cSegmentValue = cSegmentArray[Value % 10];
if (DecimalPoint)
cSegmentValue = cSegmentValue & %m;

//set up ports
MX_7SEG1_COMMON_TRIS = MX_7SEG1_COMMON_TRIS & %o;
MX_7SEG1_SEGMENT_TRIS = MX_7SEG1_SEGMENT_TRIS & %p;

#define MX_7SEG_COM_ANODE_%q

#ifdef MX_7SEG_COM_ANODE_1

//common anode
MX_7SEG1_SEGMENT_PORT = (MX_7SEG1_SEGMENT_PORT & %p) | cSegmentValue;
MX_7SEG1_COMMON_PORT = (MX_7SEG1_COMMON_PORT | %n);

#else

//common cathode
MX_7SEG1_SEGMENT_PORT = (MX_7SEG1_SEGMENT_PORT & %p) | ~cSegmentValue;
MX_7SEG1_COMMON_PORT = (MX_7SEG1_COMMON_PORT & %o);

#endif

//undefine symbols
#undef MX_7SEG1_SEGMENT_PORT
#undef MX_7SEG1_SEGMENT_TRIS
#undef MX_7SEG1_COMMON_PORT
#undef MX_7SEG1_COMMON_TRIS
#undef MX_7SEG_SEG_PORT_%a
#undef MX_7SEG_COM_PORT_%b
#undef MX_7SEG_COM_ANODE_%q


The above solution worked for me, i hope this helps.
