Years ago my company built some circuit boards based on the atmega8. It was way before arduino came along. It was in around 2003, so the company has long been closed and lost track of all the people that helped develop code and design the boards for us.
Fast forward 15 years later and people are still using the boards and want updated firmware to change some operating features. I've learned my way around the basic code, but can't seem to figure out how to do what I'm doing.
We used to just use a straight parallel cable to program them. Now with the parallel port being a thing of the past, I'm also thinking of trying to update that. We had a windows GUI that would allow you to change settings on the board through the parallel cable. These days I'm thinking it would have to be done with like a USBasp programmer. But I have none of the source code for the windows software.
First thing is I need to find help changing the firmware. Ideally, I could find someone to cheaply help me with a gui. The problem is, since this is a basically dead project, I'm not going to be making much money off the deal, if any.
I've tried to find someone through the usual freelance websites, but all I seem to get are big businesses that are quoting me thousands of dollars.
Is there any place that I might find help a little cheaper? I understand designing a gui is going to take some fundage, but is there any place I might post trying to get someone that might like to make a few bucks by looking at the code for me?
Thanks for any help!
