There are not those numbers on the Serial Monitor.

Received the message:
Binary sketch size: 3936 bytes (of a 32256 byte maximum)
avrdude: verification error, first mismatch at byte 0x0080
** 0xff != 0x23**
avrdude: verification error; content mismatch

Why? I have a liquid crystal indicator of 128x64 pixels. I need some big arrays pictures about 8-10 kb.

Looks like a connection problem. Are you able to upload one of the larger examples? A solenoid near the USB cable? Speakers? Long cable? Hub in between?

Various programs are stitched without problems, except the big array. Try to check, it seems to me that this problem in the loader.

If this is a problem with the loader, then it should disappear when you fill your array with more random data and no 0xff.

There is definitely a problem with the bootloader and avrdude, where data which happens to end in 0xFF is not sent.

Adding a non 0xFF byte should fix it.

Thanks all. I will try to use less 0xFF. By the way developers in a course? I hope will correct the bootloader and avrdude.

P.S. A solenoid near the USB cable? No. Speakers? No. Long cable? No.(Standard with Arduino). Hub in between? No.

Silc:
Thanks all. I will try to use less 0xFF.

I meant, no trailing 0xFF. Using “less” won’t necessarily totally fix it.

Hi,

I am facing the very same bug :0 :0 :0

As I am displaying image on a 32x16 LED Display, I have no ther choice to havr plenty of byte code 0xff which represent the color white :smiley:

Any hope to see that bug corrected one day ?
