Thanks for help. The old WinAVR was the problem. The avrdude was 5.10. With the newer 6.3 the flash will be erased!

- low_code_clear needs a reset of the cursor - vertical addressing mode only writes the left half of the display but when you solve this: 

> That's likely an issue with the init sequence. Thanks for the hint. I will change it.

You collecting 16 samples. Divide them by 4, and in the end again. So it is just a mean. You need a new temptable for oversampling. Or do we miss...

Yes, I see what you are doing. You make an oversample in the beginning. But in the end you have just a mean, because all bits you take are gone....

Your mean is just a little bit more hidden.

Right, this will work for your AD595, but on other thermistors you can't simply use the result of the oversampled ADC. You need also a 12bit temperature-table.

This Tronxy-stuff is a Sanguinolulu v1.2?!? It has the same pins etc. Also the Tronxy-Printer? Do we need it? It has a buffer of 96? http://forums.reprap.org/read.php?146,705869,705869#msg-705869 http://forums.reprap.org/read.php?147,33082,705240#msg-705240 ![screenshot at 2016-09-07...

Yes, maybe a Melzi. I only diff the board.sanguinolulu v1.2 with tronxy. And there is nothing different except a fan.
