I took a look for one and the only one I can get in the UK is really expensive in comparison so thought I should leave it until speaking to you guys again. I will get one and let you know what happens Thanks again
I've just realised when pressing the menu button it makes a strange clicking noise each time but only when under power with or without the tube plugged in. I think the noise comes from the alarm speaker but isn't a beep.
It sounds like your microprocessor is at least partially functional. Otherwise you wouldn't be getting the sound effects or the boost voltage to light the tube. Although it is possible that the upside-down vfd may have caused some damage to some of the output pins that control the VFD.
But before replacing the processor, look carefully at the VFD in the socket. The contacts in the socket are easily bent when removing a chip. Make sure that all the contacts are straight and making contact with the chip itself.
Hi yeah all because of a stupid mistake. It would probably have been easier to get a new kit. But looking on the positive it's a learning curve and I get to tinker with something new ie programming chips. Who knows what next. Thanks for your help, I'll let you know how I get on.
got the new chip, built the USBtiny, tried to program using command line c:\>avrdude -c usbtiny -p m168-U flash:w:newfirmware.hex
and got the following message
avrdude: AVR Part "m168-U" not found.
Then it lists all the parts and chips etc. The USBtiny green led lights OK, my PC picks it up OK and the drivers are OK. I did not see the red led light. I've tried following all the tutorial notes etc but there is a lot to take in but I'm obviously missing something Hope you can help.
