Adjustment for interval timer "MMA"


We have a product which is already running in serial production since years, but the single interval times are a little bit unexact - they need to be adjusted. (12 functions). Also length of beep sound need to be adjusted.

For the running production I need the software for the ATMega16-16AU (TQFP44). This microcontroller will be obsolet in future and the replacement will be ATMega16A-AU. both microcontroller are quite similar but some ports address have changed. So I would need software for both microcontroller. Is that include?

The current software is made in assembler. The software can be adjusted in assembler or made new in C.

You flash the new firmware on a device. (I send you one timer)

For proofment of correct function you send me a video of the running device. (you can fade in a stopp-watch to proof the correct interval times)

Currently I use AVR Studio and STK-500.

I need all neccesary information for flashing the new firmware. (e.g. all settings in AVR like fuses and so on...)

I tried to do this job befor with a different freelancer. Unfortunattely with was not able to flash the device, so he was also not able to proof the job. I canceled the profect by half with him, but he gave me the code. I was not able to flash the code and see if it´s running. You can check out his code (see in annex „IntervalTImer Code.7z“) , maybe we can use it.
