not successfully
2  Using Arduino / Microcontrollers / can't load hex using Sparkfun tiny programmer on: August 06, 2014, 12:18:32 pm
I'm trying to load the Mono OC hex file from the attached source from this site :
http://elm-chan.org/works/sd8p/report.html

I'm using the tiny programmer from sparkfun and avrdude.
see attached image.

any suggestions on how to make this work?

others have successfully loaded the program onto the attiny85 chip, seen here:

i would like to do the same. Thanks for the advice.

Any other advice? this has to be possible....

DAMN IT!!! I CANT GET IT TO COMPILE!!!

others have done it... thats odd.

there are a lot of videos of people who have done it:

hmmm... if i burn the 8mhz boot loader and try to load the .c files would that change anything?

I think I'm going in circles. based on the source code how can i successfully load it on the chip?

its a raw chip. should i burn the boot loader to it using the arduino ide? will that help?

I've attached the source.

I'm not quite sure mike.

i feel like I'm very close...whats going on here?

Great.

Im tryting to flash the 85 and i get the attached output...im not sure if it worked.

I have the SD card to FAT32 and a folder called wav with one wav file in there called

OtherWAV1.wav

can i use this capacitor...i don't know if its right
12  Using Arduino / Audio / Re: Saving a short wav file to Attiny85 via the sketch/memory? on: August 04, 2014, 03:22:00 pm
understood.

I have a bunch of (LH1156AT) optoisolators
http://www.techno-star.biz/others/lh1156at.pdf

would this be something that i can use?

i noticed you have an on switch. is it possible that the num pad can turn on the circuit (maybe with a timer) turn it of (maybe with a relay or something - i have a 6 pin digital relay)

Thoughts?

thank you mike... ill take a look!

Also, going through various tutorials, i see that the at tiny will loop through the wav files on the card while power is on....

what about pressing a button to play a file?

So, the project is a box my wife will keep on her desk. when she presses the button the audio file should play. But I was thinking is it possible (to save battery) that the audio only plays when she presses the button? In theory: turns on the circuit plays and turns off the circuit? How do those hallmark cards work? are they always on?

Thanks
Keith
