Hi Russ

i am trying to implement a 6 digit display

the problem is my variable Max_Disp which holds the data that is displayed

can only hold up to 5 digits so 12345 displays ok but when its 123456

this is grater than a word variable can hold so i need so help in how to do this i am following all the advice given but still lost

Regards

ISAAC

Code:

Again:
Max_Disp=12345
Gosub Display ' Display the Value of Counter
Pause 150 ' Delay, so we can see whats happening
goto again
Display:
Digit=0 ' Start at Digit 0 of Max_Disp Variable
For Position=6 to 1 step -1 ' Start at Farthest Right of Display
Register=Position ' Place Position into Register
R_Val=Max_Disp Dig Digit ' Extract the individual numbers from Max_Disp
If Max_Disp<10 and Position=3 then R_Val=15 ' Zero Suppression for the second digit
If Max_Disp<100 and Position=2 then R_Val=15 ' Zero Suppression for the Third digit
If Max_Disp<1000 and Position=1 then R_Val=15 ' Zero Suppression for the Forth digit
If Max_Disp<10000 and Position=0 then R_Val=15 ' Zero Suppression for the Fifth digit
If Digit=Max_Dp then R_Val.7=1 ' Place the decimal point, held in Max_DP
Gosub Transfer ' Transfer the 16-bit Word to the MAX7219
If Digit>=5 then Digit=0 ' We only need the first 6 digits
Digit=Digit+1 ' Point to next Digit within Max_Disp
Next Position ' Close the Loop
Return ' Exit from subroutine
' Send a 16-bit word to the MAX7219
Transfer:
Shiftout Dta,Clk,msbfirst,[Register,R_Val] ' Shift Out the Register first, then the data
High Load ' The data is now acted upon
@ Nop
@ Nop ' A small delay to ensure correct clocking times
Low Load ' Disable the MAX7219
Return ' Exit from Subroutine
