Microview Code Uploads then doesn't

Development Boards Arduino

Hello,

I’m having issues with my Microview. I’ve uploaded a program and it works perfect…but when I edit the code just slightly then I get the following errors:

Arduino: 1.8.12 (Mac OS X), Board: “Arduino Uno”

Sketch uses 14804 bytes (45%) of program storage space. Maximum is 32256 bytes.

Global variables use 1371 bytes (66%) of dynamic memory, leaving 677 bytes for local variables. Maximum is 2048 bytes.

avrdude: verification error, first mismatch at byte 0x30d8

0x4a != 0x4e

avrdude: verification error; content mismatch

avrdude: verification error; content mismatch

**As a note I changed a temperature setting (hightemp = 125 to hightemp=127, and lowtemp=59 to lowtemp =61) and the program will compile fine but won’t upload now. However if I change the code back to the original it uploads just fine.

Was this a custom sketch or one our example sketches?

It was custom. I’ve included the sketch as a .txt file

Also I’m using the same settings shown in the Microview hookup guide:

Board - Arduino Uno

Port - /dev/cu.usbserial…

Programmer - USBtinyISP

I just tried this exact same thing with another Microview and it works fine. Should I burn the bootloader for the other Microview to fix the issue?

If your other MicroView is operating correctly, then I would agree that it’s worth a shot. I can’t guarantee that this will fix the issue, but it’s the next logical step. If it doesn’t resolve the issue, then please let me know.

Burning the bootloader using an Uno board did the trick

That’s great, glad to hear it.
