Anyone know of a source to buy a legit Atmel tester in the form of a T1, T2, T7... I like the convenience of the package...
Hello, what are the problems if I have a tester with a fake (or not Atmega) CPU ? Do they work not good ? Or there is no bad effect ?

Aldo22 Because you misspelled the post number in your link. It should look like this

I did read the encoder part but pd1 and pd3 are not connected at my lcd is it best to just solder to the ic or is there a better way to solder connections.
ps also looking to get a different screen would you know which is best for this device and would it benefit me to put a 1200 crystal just cause i have 1.

Any ideas for a noob like me on where to start with trouble shooting?

For instance, -fno-jump-tables will reduce my current v1.50m build from 32072 to 32016 bytes.
And with a combination of CFLAGS += -ffunction-sections and LDFLAGS += -Wl,--gc-sections I was able to reduce that even further down to 31892 bytes.

avr-gcc 5.4.0 is the winner again.Well, and the Test button has no direct connection to the STC15
