Hi i have recently purchased an ATU-10 unit from AliExpress but I was sent and ATU-15. this looks the same and had the 1.5sw which I’ve updated to 1.6. All works ok. what is the difference between

David, I was considering adding an ESP32 to the I2C for my ATU-10; sounds like you already did something very similar. I'm not a PIC person; would it be easy for me to port your changes to the ATU-10

Sorry to resurrect an old thread, but do I understand correctly that given the circuit shown, ATU-10 matches will generally be more low-pass in character?

Where is the starting point? ?Is it the tune.c you recently posted?

Paul, you have to choose needed PIC manually in the menu

There are opensource ATU projects out there that already cover most of those requirements. Maybe its time to forget search algorithms altogether and move to using the like of the AD8302 gain phase

People, the Atu 100 algorithm is out of date. Is somebody able to port the algorithm from ATU-10 ? I don't have a time and also I don't have needed hardware setup to test it.

well i have found my pickit3 and am haviing to use my win7pc as the pickit wont work on my win 10 pc,it says nothing detected,see screenshot,does that mean its dead,if so why did it happen?

I tried sending you a zip to the email address on your qrz entry but it bounced. David M0TGC

this pickit 3 sw wont open or run on my win 10 64bit pc,is there anywhere to get a version that actualy works?,if so can you give a link?,cheers+73 regards Paul m3vuv

Very useful thread, thanks guys. I have an ATU1000 that I have modified to use I2C to control it from a Raspberry PI.? I tried to use the I2C that drives the display but gave up because the display

David, Thank you so much. I have found the manual, and seen the info at the end, which looks most useful. As said, I am not a computer expert, and for me, this (firmware settings) is harder than

Geoff, read the cells description in the end of manual. You will need to change many cells, according to your setup.

I was looking at coarse_tune() function.? I'd missed that you start with step=3. For the L_linear!=0 case, you do 11 steps of 3 (*L_mult), there will be a grey code for this. Searching non-linear

Hi, Tom I think we can remove the step size correction in for(), try this I also fixed under 64 limit

Hi, and thanks for the reply.? That display looks Interesting.?So you are saying the actual firmware is the same for the at-100, and the atu-1000?That's good news if it is.Next problem is getting

Hello, Roger This tuner doesn't step with smallest step every time. It steps with some random step, depends on..... So Gray code is useless here in any case.
