Need C programmer to fix bug for controller by ATMEGA32A

Postby Speedythinker » Fri Jul 17, 2015 6:59 pm

Hello folks:

I found that there is a bug happened in our new water chiller. Getting help from the tech support in China is a big challenging task!

The chiller won't be able to shut off when press the On/Off button unless doing for 3 times. It could shut off only if the 'differentiate' temperature is not reached and a control value was not triggered. In order to it shut off, we have to press the On/Off button for 3 times (the chiller reset itself woke up twice). I got the C sources code but I'm not good at micro-controller programming. Please let me know if anyone can help

If return for favor, I can trade the parts you want.

How would one go about testing it?

I think any number of us could help you, Marco. Someone would need a unit or at least the controller board for testing. Is the ATMEGA32A set up on the board for in circuit flashing? Or did they use a 40-pin DIP in a socket?

Thank you for all your support. I found someone to fix the problem and so far so good. The turn On/Off issue fixed. Now it just left a little bit 'cosmetic' issue need to fix and it is no longer affecting the operation.

Very appreciated for the support!
