need help in lookup

please help i want to shiftout numbers from 0 to 9 .i used data eeprom it works good but it pause at 0 , now i want to use lookup or somthi9ng without saving data in eeprom .i want to shift out numbers to the leds using ic 74hc 164.it works when i use this (data @ 0,252,96,218,242,102,182,190,224,254,246) but i want to use lookup or other way not to save in the eeprom please
this my code but doesnt work it sends unknown digit .

Looks as if you almost got it, move your lookup routine up in your code to somewhere before the shiftout statement.

Code:

Include "modedefs.bas" B2 var byte B1 var byte SDO VAR PortB.0 SCLK var PortB.1 portB = 0 'set port latches low prior to tris TRISB = 0 'set all portB as outputs porta = %0000111 'set this way because ??? 'SCLK = 8 b1 = 0 b2 = 0 main: for b1 = 0 to 9 + 1 lookup2 b1,[252,96,218,242,102,182,190,224,254,246],b2 'these numbers i want to shoutout them to the leds from 0 tro 9 SHiftOUT SDO,SCLK,0,[b2] pause 1000 next b1 goto main

I changed your vars to byte as the were all less than 0 to 255
I cleared the vars before the main loop

thank you very much joe for helping me .have a great day .

Hello malwww,
If you have been following other threads, you have seen a similar one to yours. If you are using byte variables only then use lookup instead of lookup2 as the code is 1/3 as big and you can use a table of up to 255 choices. Lookup2 gives only 85 choices, which can be byte or word variables.

hi joe thank you again for explaining to me ,i have another question please if you dont mind...i i want to write atring (lookup) to the external eeprom then i read it and send it out just to get more ideas bcz im new in pbp ,but its easy to lern than asm. have a great weekend joe

GOOD ! Glad you have it working the way You want it.
Now I am curious, what are you making? I am guessing
you intend to do more than store 0 - 9 in the eeprom.
There are dozens of examples here to do something similar
to what you have in mind, whatever it is. Google can search
just this forum if you use this link.
http://www.google.com/custom?hl=en&c...ch&sitesearch=
just check the check box that says, Search picbasic.co.uk. and you are set.

thank you joe for explaining to me things ,im always here,i really want to lern pbp good bcz im interesting,i posted another thread about VGA box if you have any ideas i want to share with everyone so we can build it , hope you are doing good .!

Hi malwww,
I just added to this post based upon helping you, you may recognise some of it :D

thank you so much joe,its good i got more ideas from that thread you added,see you soon joe

hi again joe.
im trying to make a counter from 0 to 9999, i want to use the same code u fixed for me' well i use 74hc164 and 4 digit l7segment leds now i want to write a variables for 4 digits and shiftout, if it will works please im putin digits in porta.0 to 3, im confused how to use a variable works with shiftout, have a great day Joe .!

Hi malwww,
are you using the eeprom in this counter or just a display? Are you wanting to load count into eeprom and then display the results or just count to 9999? Am I correct in assuming SDO & SCLK are for the display ?

It is pretty easy once you get the hang of it, overflow your counter variable into another variable and sort @ display time using the DIG statement. Look at this thread to see how, post #9 is where I posted the code to which I refer. http://www.picbasic.co.uk/forum/showthread.php?t=9037

hi joe im using the eeprom to save data and count them,just want to know how to vary the digits when enable digit 1 it shift out the data or number to digit 1 then digit 2 so on and remember im using shiftout to 74hc164 to drive 7 sigment digits,i want to drive 4 digit with shiftout, i will check this thread you gaved me thank you so much joe

I buy 4 digit displays from http://www.sureelectronics.net/ , usually through their eBay store. For about 15 US you get an spi display that works exactly with the code in your lookup table and it is about 32mm tall, 1 1/2 inches tall. These displays can be hooked together using cables supplied with them to make several digit displays. BTW, God helps us every day, that's why we do not starve.

hello joe i wrote this code now it works the 7segment and shiftout .but when i vary things it doesnt works and it doesnt show me things, i want to know where i put a variables and how, is pic cant run 2 things in the same times ? (variables and shiftout with digit out) and i keep the shiftout how it is now , please help now it show me 3210 on leds 7segments ,sorry i cant find lcds in my country and i cant send money to buy from europ or usa bcz they dont alow us to send money out, i need to call my friends in spain to buy me them but it will take long 'now im new in pbp i want to learn a bit good and sorry about my english , thank you joe

You need to put in the REQUIRED code to disable analog stuff for your chosen PIC too or it will not do the digital dance. You need to define the TRISA values to make the proper ports inputs or outputs.

OK I am not clear on what you want to do. Are you still wanting to retrieve your lookup from external eeprom? Because that is way more code than pulling it out of your main chip. Look at my tachometer code. I stored those values in the on chip eeprom, but I could have just as easily used a lookup table in code space, the primary immediate advantage to storing it in eeprom, is if you change to a different display you can easily change the eeprom data, to match.

thank you joe, the problem i have is not lookup or eeprom or lcd,the problem is when i put variables the code doesnt works, like when i put the variables with the code above. i have problem when the pic start it losts betweenm the main shiftout and the variable so it doesnt work bcz im pausing the variable 1000 and shiftout is too fast so can i see the numbers on lcd ,the lcd and numbers shown good but just i add any variables it doesnt work or shift out things , i use pic 16f84 i think it hasnt analog stuff , thank you joe for your best

thank you joe for helping i did that code im still fighting with it it didnt work but its good i have took some more ideas about variables , have a great day .!

It works here, I tried it first on 16f690, and this version on 16f628A, 16f648A and it works on both, I uses a simple blinky to drive the count as it's output is clean unlike a switch.

Shiftout SDO,SCLK,4,[ONES\8,TENS\8,HUNS\8,THOUS\8] 'when it shiftout it needs to eneble each digits bcz i have 4 wires i 'donno where i add them in this code so when it shiftout the 0 dig it enebles digit 1 on lcd then 2 so on i use digital satellite receiver 7 segments 4 digit it has 74hc164 for serial input data and clock then paralil output to 7 segments and each 1 wire ,from each digit i wanted to plug them in the pic so i need to eddit the code im still trying lol'
PAUSE 10
HIGH PORTB.7
pulsout DLE, 125
pause 12
Goto MAIN

end

OK, it took some hair pulling as I am not really good with arrays.
here is a sample as to how to do this. What you want to do is load the variable with the value to display, and display that digit, then do the next and the next. Using an array to hold the value:

Code:

Goldfish var byte ' cause it's late and I am tired Digit var byte[4] ' 4 variables all named digit, an array index var byte ' a counting variable displays var word ' from the program digit_output var byte 'from the program ' this code changed from program loop: DIGIT_OUTPUT = DISPLAYS dig 0 ' Load Thousands Digit READ DIGIT_OUTPUT, DIGIT.0 ' Convert and Load Thousands Variable DIGIT_OUTPUT = DISPLAYS DIG 1 ' Load Hundreds Digit READ DIGIT_OUTPUT, DIGIT.1 ' Convert and Load Hundreds Variable DIGIT_OUTPUT = DISPLAYS DIG 2 ' Load Tens of Units Digit READ DIGIT_OUTPUT, DIGIT.2 ' Convert and Load Tens Variable DIGIT_OUTPUT = DISPLAYS dig 3 ' Load Ones of Units Digit READ DIGIT_OUTPUT, DIGIT.3 ' Convert and Load Units Variable ' notice the digits were changed to reflect the array variable name 'here is where we do the magic for index = 0 to 3 ' loop 4 times Goldfish = digit[index] ' load goldfish with the digit values shiftout SDO,SCLK,4,[Goldfish\8] ' send the values to display portC.0[index] = 1 ' here we energise each display digit in sequence PAUSEUS 900 ' this number alters the brightness verses display flash rate PORTC=0 ' this blanks the numbers between loading data so it does not read 8888 next index ' select the next digit GOTO LOOP

you notice the word index in red, this syncronizes the digit selection on portc with the data being shifted out.
