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 doing

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.

Hi, Geoff Looks like the MCU FW is protected to be read. You have to erase it and configure simple ATU100 FW before upload it . It has a price, but it is bigger OLED you can use here

I think I've discovered a tuning bug. For some of my test points, a relay_set of -128 will occur. During the fine tuning, a char overflows at the start of a for loop in the code below. My current

I've used 74HC595 for LED displays (driving ULN2003s).? I've wondered about these, and given the low switching frequency, it's an option. By moving the pins around (and using the MCLR for the tune

1. Yes, I want to add

Frequency status: I've looked at a few RF frequency detector designs, and have worked out a prototype (aka Mark I). It uses a 74AHC14 Schmitt trigger inverter (good to 125MHz) on the front end with a

on your point four Roger, how about a couple of I2C parallel ports or shift registers on the RF deck to drive the relays, a significant reduction is connections between boards...

1) Moving the code to the RP2040 from the Raspberry Pi foundation. This would make it easy to add a WiFi interface for remote control and display. The RP2040 is not very expensive, $4 without and $6

Hi Roger, I think all of the additional features and suggestions from others are perfectly valid. From an operational side of things, the ATU-10 features such as latching relays and updating via USB

During the full capacitor and inductor searching, the current code uses straight binary values (with a change in step for the higher values). So the smallest capacitor relay does a lot of switching.

Starting from scratch would have been a lot of work, but adding frequency measurement doesn't look too bad, and the rest if software!

I also can't figure how Gray codes would be used. That's quite a bit of work you've outlined Roger!!!! I'll add the things I've been thinking about. 1) Moving the code to the RP2040 from the Raspberry

Finished the test code and checked it in at https://github.com/tomcourt/tunetest I'd tried to port it to Visual Studio, no complex data time so I tried to roll my own. Way too slow. So I ported it to
