Oh god no ! I have too much junk around the house already, let alone vats of acid laying about.

I'm planning to go more along these lines (not necessarily this but similar):

Yeah jonne, if you don't mind what did you do to make the boot loader compile? I had gotten it pretty close but was getting an error about finding a file... The last I remember compiling it? Thanks!


Also, Albertinjo - That works awesome! Putting a 100uf cap between the lcd and gnd completely removes the flicker in my screen. Thanks!

I compiled it in linux. Here's my makefile. I can't help more until you tell the error you're getting.

Hey Jonne,

I compared makefiles and the only difference beside our home arduino directories (Program Files (x86)/Arduino) was this:

Code: Select all

#GCC = $(BIN)/avr-gcc
#COPY = $(BIN)/avr-objcopy
#DUMP = $(BIN)/avr-objdump
GCC = avr-gcc
COPY = avr-objcopy
DUMP = avr-objdump

but that was pretty irrelevant, as I obtain this error whether I input the 3 lines of code or not...

Code: Select all

 makefile:51 *** missing separator. Stop.

the line 51 contains: .PHONY: all

not sure what separator it's looking for... :{

Thanks!
