problem with the program....

[jabern]

what's wrong with this program? if i build this on the MPLAB.. the result is failed... why? there's one error... i don't know where is the error.. pls help... me.. this is a 8x10 Led Dot Matrix.. that display... AMATURE RADIO TRANSMITTER CIRCUIT... pls help... i copied this program on youtube.. im a new to this program... the pic that i used is PIC16F84A...

what is the dollar sign mean? is it a character in the program? thanks for the help...

---------- Post added at 23:16 ---------- Previous post was at 21:22 ----------

:!::!:help!!!!!!!!:!:

 

[btbass]

What was the error message from the assembler???

The $ sign means the current location, the pc value.
GOTO $-.2 jumps back two locations.

 

[jabern]

what shuold be hte correct program so that there will be no error when rebuilding the program? thanks!

---------- Post added at 23:35 ---------- Previous post was at 23:34 ----------

im a newbie for programming... so i dont know what is this all about... we (group) have to make this project.... thanks!

 

[btbass]

What was the error message from the assembler???

 

[jabern]

Link failed

 

[microlab]

hi

have you added the assembly program you write to the project?
just copy/paste the error message you saw on MPLAB will make things easier to understand

ml

 

[btbass]

In Mplab, try selecting the option

Project/Set Active Project/None (Quickbuild mode)

Then try to assemble again.

 

[jabern]

Error - section '.org_2' can not fit the absolute section. Section 'org_2' start=0x00002007, length=0x00000004 errors : 1

 

[btbass]

Get rid of the 'GOTO MAIN' at the very end of the program. You don't need it.
The reset vector is at 0.

Address 2007 is the configuration register.

 

[jabern]

Thanks btbass... You're excellent... Btbass... Favor pls... Can you help our group pls.. We are a college students.. Hi! Our group want to make a 30x7 led dot matrix.. And our professor dictate us to have a display of on-air and off-air... Because our prof. Want to put that on our campus radio station.. Pls. Help us.. That is our project.. We want a schematic diagram of the circuit and the assembly program.. We are new to this kind of programming.. Pls. Help us! Tnx!

 

[btbass]

Thanks for the flattery guys but this is something I'm sure your professor would like You to do.
Only by doing will you learn which is the point of the exercise.
Google is your friend here for research and if you have any questions or problems,
eda forum is here to help you.

 

[jabern]

haiz... we have no time to study it one by one because our deadline of our project is on Friday this week....



that is a 10x8 dot matrix schematic diagram.... pls. help us to make it 30x7 that display ON-AIR and OFF-AIR.... and using a selecting switch by displaying ON-AIR if it is "On-Air" and selecting the switch again to display "Off-Air"...

This an Example of the display 10x8 Dot Matrix That Display AMATURE RADIO TRANSMITTER CIRCUIT.. this circuit gave to me by the friendly man on youtube.... thanks! anyone there.. pls. Help us on our Project...
