Hi Tim,

When it comes to the EE data, I can make a copy of it, because I have worked out the topic ... see the attachment.
But it's not just about EE, so EU2AV wrote to me that there are even changes in Flash, I don't remember what it was about, whether it was a power measurement gear or something else, and that's why it was done on version 2.7 because in version 3, x broaks memory space.
That's why I'm asking, maybe David will suggest something?

Hi Marek,

3.2 works fine in the ATU1000

BUT... Make a copy of the eeprom data 1st. ( this is what I didn't do with mine and it took a while to work out the cell values )

This is because the EU2AV version uses different L & C for the tuner and you will also need to know the turns ratio for cell 31 and check that cell 30 is set to 01. All that is in your eeprom data

When you update the s/w to 3.2 you will have to input the cell data you copied from your old version and write that to the PIC.

You can then do a read of the PIC to make sure that all is as expected and then export that as a hex file as a backup for just-in-case.

regards

Tim

Hi,
I made a 1500W tuner according to the EU2AV scheme (PIC 16F1938 processor).
David N7DDC firmware based on old version 2.7.
Question for David,
is it possible to do it on software version 3.1 or 3.2 and display the correct power value?
