| need help |

This code work fine as i want. This code read ADC from AN0 & display it 7 seg. Here i indecte AN0 port display it 7 seg.
As I-P
But one confusion with me. How can I display AN1, AN2.
Those are need indication O_P & Lod & reading ADC from AN1 & AN2 display it 7 seg.
| Code: |
/* 16F7 Configuration dual I|P
O = Output, I = Input RIGHT NOW AS DEMO
_________
MCLR | 1 28 | RB7 --> (O) == A
(I) ADC1 --> AN0 | 2 27 | RB6 --> (O) == B
(I) ADC2 --> AN1 | 3 26 | RB5 --> (O) == C
(I) ADC3 --> AN2 | 4 25 | RB4 --> (O) == E =as D
(I) ADC4 --> AN3 | 5 24 | RB3 --> (O) == D =as E
(I) SW --> RA4 | 6 23 | RB2 --> (O) == F
(I) ADC5 <-- AN4 | 7 22 | RB1 --> (O) == G

Sit down and THINK.
Start by working out what you want the display to look like.
Say:-
1) Show text "O_P" for 1 second.
2) Show value for AN1 for 1 second.
3) Show text "lod" for 1 second.
4) Show value for AN2 for 1 second.
5) etc then loop back to (1).
When you've decide what you want it to look like, start coding.
Whilst you're at it read the CCS manual.
The CCS way of doing things avoids working on registers like the plague.
Mike
PS How many projects do you have going at the same time? |

yes ur thinking near to me .
those i want to display ,
1) Show text "I_P" for 1 second.
2) Show value for AN0 for 3 second.
3) Show text "O_P" for 1 second.
4) Show value for AN1 for 1 second.
5) Show text "lod" for 1 second.
6) Show value for AN2 for 1 second.
7) etc then loop back to (1).
but confused how can display rest text ( "O_P" & "lod" )

| MATH results for the index?? |
| Posted: Wed Jan 29, 2014 3:37 pm |
|
|
math??
| Code: |
const char CA[11]
...
static char I_P[3]
|
then later
| Code: |
I_P[0]=CA[15*Num/10230];
|
where Num is a 32 bit integer
and the adc result is 8 bits,
i have some trouble with what is intended by the code.
There is much that is puzzling here, but
my concern is that the ultimate results of the [index] calculations
are in bounds of the declared arrays..  |

You've got another thread running in parallel with this one.
You're having difficulty understanding how to drive a multiplexed display.
When you've got it sorted out on your other thread, the solution here will (hopefully) become clearer.
I don't intend going through the process twice.

i have got another thread running in parallel with this one. becose there my problem is 7th bit {SEG_(G) <-- RA4} . which re conteced with RA4.

Please explain the problem with RA4 in a way I can understand.

The problem may be hardware related as that pin RA4 is 'open collector ' NOT TTL according to the datasheet, page 8 ,table 1-1. Unless there's a pullup resistor on that line it won't function like the rest.
You've changed the hardware and NOT corrected the comments at the start of the program, which is very,very confusing!
Most, if not all, 'seven segment LED display' program use the entire port B for the 'segments'( a,b,c,d,e,f,g,dp).It allows for EASY programming and ESY debugging of hardware.Also, there's a LOT of program examples on the web setup this way.
By spliting the segments over two ports, you've got a LOT of extra code that isn't necessary AND unless you deiable all perpipherals to those pins ,can run into 'issues'.
I strongly suggets starting over...

Probable simplest solution:-
Create extra elements for your CA[] array. One for each extra character you want.
You've done a 'special' character labeled 'OFF', so should be able to add the code you need.

RA4 is not the problem with your 16F676 project. This is NOT the place to discuss a different project.
To avoid further confusion please reply to my latest post in your other thread, I will then respond in that thread, and not here.

i do there | Code: | static char I_P[3] = {0x30, 0x40, 0x73}; // FOR CC
// I - P //
// unsigned char CA_P_1 [] = {0xC0, 0xBF, 0x8C}; // FOR CA
unsigned char O_P [] = {0xBF, 0x40, 0x73}; // FOR CC
// O - P // |

Sorry, missed that nugget (can't see the equivalent for "lod").
There are several ways you could display the text you want.
Probably easier for you to call a Text_To_Symbol() routine instead of HTO7S() when you want to show a text message.
Text_To_Symbol() simply puts the data you want into the I_P[] array.

Nearly a week ago you said you wanted this:-

1) Show text "I_P" for 1 second.
2) Show value for AN0 for 3 second.
3) Show text "O_P" for 1 second.
4) Show value for AN1 for 1 second.
5) Show text "lod" for 1 second.
6) Show value for AN2 for 1 second.
7) etc then loop back to (1).
|
The contents of your IP[] array are continuously displayed as a background task (ie via ISR).
So "1) Show text "I_P" for 1 second." becomes:-
| Code: | copy CA_P_o[] array to IP[] array;
delay_ms(1000); |
You've already got a routine for hex to symbol (i.e. your HTO7S() routine).
Adapting it to copy CA_P_o[] array to "I_P" array should be trivial.
Then "2) Show value for AN0 for 3 second. " becomes:-
| Code: |
set_adc_channel(0);
delay_ms(1);
result=read_adc();
HTO7S(result);
delay_ms(3000);
|
Etc.
No need for me to write any code for you.
OK, there's a lot of repetition.
Get the thing to work as you want it, THEN refine.

Thank you sir
My problem has solved.
Now i add one push sw .
Those function are as:
| Quote: |
* Display Procedure:
* step 1
* 1) Show text "I_P" for 1 second.=currentDisplayMode = 1
* 2) Show value for AN0 for 3 second.=currentDisplayMode = 2
* 3) Show text "O_P" for 1 second.=currentDisplayMode = 3
* 4) Show value for AN1 for 1 second.=currentDisplayMode = 4
* 5) etc then loop back to (1).
* its roll over
* step 2
* when I press C0 till 100 ms or 500 ms stop step 1 &
* display hold on currentDisplayMode = 1
* if again C0_PRESSED increment currentDisplayMode +1
* if C0_PRESSED long 1000ms till. then exit from sw scan mode(step 2).
& continuous step 1 |
but sw function not work properly .
| Quote: | #INT_TIMER2
void scan_mode(void) // scan_mode with sw
{ while(C0_PRESSED)
{ mode=1;// count=1;// currentDisplayMode = 1;
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =2
mode=mode+1;}// count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =3
mode=mode+1;}//count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =4
mode=mode+1;}//count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =5
mode=mode+1;}//count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =6
mode=mode+1; }//count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =7
mode=mode+1;}//count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(C0_PRESSED){ //agen C0_PRESSED increment currentDisplayMode by 1 =8
mode=mode+1;}// count= count+1;}// currentDisplayMode = currentDisplayMode + 1;}
if(button(PIN_C0, 0, 100, 2, C0, 1))//if C0_PRESSED long 100ms till. then exit form sw scan mode
C0_PRESSED=TRUE;
else
C0_PRESSED=FALSE;
// count= 0;
