You should say "less expensive"

It's natural rubber O-rings. 2 cents each is less than "less expensive"

Once I convert the Jpg, where do I put the file.

Can I display a bitmap file without conversion.

Assume I use this code to reference the file extern "unsigned int File name[????] what goes in the brackets?

How do I call the file into the code ie drawBitmap(file name)

Does the bit map need to be a certian Bit Depth?
Sorry DQ828

I still can't properly display a bitmap onto the screen, only part of it. I always get the "file too large" message.

Just reporting back my clock problem.

root cause was the 45.x clock. removed the 100nf caps on both 45.x and 49.x and all working.

probably caused by an accident on my bench but not too sure at this point. It does not make sense that this cause a blown clock on the ess board.

hope you resolve your problem bigpandahk

I'm following this thread closely cause I have a dual Biii coming up.
Want to use the hifiduino cause it inspired me for my dcb1 control unit.

regards.

My efforts failed, I got as far as having the file compile, but it fails when trying to load, I have put a question on the Arduino forum.

The main problem is when converting the bitmap to C code, there are several parameters but without information on how to set them. We have to try and error.

Good to hear. Make sure you have static protection. Happy to hear you got inspired by hifiduino :-)

The arduino code is easy to use. I refactored the hifiduino into a more object-oriented approach. I kind of made it hardware independant. That is, a volume class is to control volume regardless of which input device is used (apple remote or push button). The underlying device code is just bound in as a library. It made it easier to bind to new controlling devices like , for instance, the DCB1 controller. It also makes it easier to add in new i/o devices. IE: My next step is to control hifiduino through the USB port. I already have the prorotype in a vs2010 project. I merely need to give it a UI and its done.

kind regards.

I was converting jpg to C code but tried saving the file as a png & then converted to C, it loaded but & displayed but did not display 100%. The images have to be very limited in size, a seemingly small file (in today's terms) is too big when converted. When the file is too large, they normally wont compile.
