Hello all,
I have spent the last week trying to upload my arduino code onto the ATtiny84, and can get close, but not quite make it.
Firstly, I have downloaded arduino-tiny-0150-0020.zip from Google Code Archive - Long-term storage for Google Code Project Hosting., and placed it in "arduino-1.0.1\hardware". This contains the board info with fuses and compiler information I believe.
I uploaded the blink sketch to my ATtiny, and everything worked fine.
Next I tried compiling a bigger file, and got several errors that all say "relocation truncated to fit: R_AVR_13_PCREL against symbol `__udivmodsi4' defined in .text.libgcc section"
The internet then said Arduino Tiny - #9 by Coding_Badly - Microcontrollers - Arduino Forum that I just need to download winavr 2010, and replace "hardware/tools/avr" with this folder.
That caused compiling to work fine on all files.
When I tried uploading however, first the "avrdude.conf" file had moved from "/etc" to "/bin", so in the "platform.txt" file (part of the initial download) I have changed the file location to reflect this.
The error I am now getting, is that when I try to upload any file, I get a syntax error from the avrdude.conf file.
In avrdude 5 the error is here:
programmer
id = "wiring";
desc = "Wiring";
[b] type = wiring;[/b]
;
the error states:
.../avrdude.conf:332 unrecognized character: "w"
In avrdude 6 the error is here:
programmer
id = "wiring";
desc = "Wiring";
[b]type = "wiring";[/b]
connection_type = serial;
;
the error states:
syntax error at .../avrdude.conf:348
So I am assuming I either need a new version of the attiny "platform.txt" file, winavr, or avrdude, but am noit sure what to do about it.
Please advise, thanks in advance,
Shane
