Hi,

I tried compiling the source code for Transistor Tester which I found 
here:

http://www.mikrocontroller.net/articles/AVR-Transistortester

And got this error on AVR Studio.

"lcd-routines.c:114: undefined reference to `uart_putc'"



any suggestion will be appreciated..

which sources?

There are the old ones, which do not have UART at all, and you can 
download pre-configured for HW UART or Soft UART. In these the error 
should appear earlier than line 114, if at all.

So it does not help, you have to post your source here....

The code I found here: 
http://viewvc.coremelt.net/viewvc/avr/semiconductor_tester/firmware/

Sorry but I can't attached the code directly here..too long..:(



when I try to compile I got this error:

1

Did I missed something?

Hi,

I do not use and know AVR-Studio...

But it does not use the Makefile, does it?
Because you do not link swuart.o, therefore it does not know the 
soft-uart functions.

Hi,

I am using Linux, and compile with the avr-gcc toolchain just running 
"make all".
But I build it ~ 2 years ago, with the "old" sources without UART.

But according to the Makefile it should still work with "make all" with 
the UART. Do not know ho to do that from AVR-Studio, since it does not 
run on Linux.

In the Makefile, $(TARGET) depends on $(OBJECTS), and $(OBJECTS) is:
1
## Objects that must be built in order to link

2
OBJECTS = main.o lcd-routines.o swuart.o

and swuart.o is build with rule:
1
swuart.o: ./swuart.S

2
  $(CC) $(INCLUDES) $(CFLAGS) -c  $<


Regards,
Boregard
