I wonder if it might work better to stick with i2c for communication. ? It's already in the code, and can work bidirectionally, so that we could send commands that way.? I see the biggest negative

Hi Dave This is just the feature I asked about some time ago, for remote operation I will watch with interest, I have modified the original code to work with a larger 20x4 line display and make it

ok, I've successfully proven this PIC can output a bit-banged uart.? ?I took one of the I/O pins (in my case, one of the input switches, which I turned into an output), and whenever the PIC writes

Can you just wire the oled and the data plug together. they won't intafear with each other? Baud rate? Ralph ________________________________ Sent: Monday, January 17, 2022 9:02 AM To:

Or you can use the esp io lines to simulate pressing the tune, auto and bypass buttons.

Yes, the ATU-100 has 2 output pins, RA6 and RA7, to talk to a transmitter. I would like to get more info from the ATU-100.? I think SENDING data out either RA7 or RA6 as a uart signal will be most

You do not need to send serial data to the ATU-100. And there is a simpler way to read the status of the AT-100 than decoding the OLED display data You can fully control the ATU-100 auto tune function

Hi Although cable is involved you might want to consider RS485 which will work over greater distances than RS232 It expects to see twisted pair which I think is 200 ohms ish. I've not tried sending

If your ATU-100 board does not have a programming header, you will have to tack solder connections to traces from the following pins on the micro, to the labeled pins on the

Dave, you seam to be ahead of me... I planned to do something similar now when I have a code base compile-able using free tools. I got the idea to use this piece of software to snoop the display

Much thanks. I couldn't find it anywhere. Ralp. WD6NGN Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ Sent: Sunday, January 16, 2022 5:45:29 PM To: [email protected]

DAT <~> SDL CLK <~> SCL hope that helps! Beau

Steve you can use 2 ports for display data transfer and using soft UART library.

Sounds great!? There is a gotcha, tho.? If I read the PIC data sheet correctly, the serial i/o goes through two pins that, on the ATU-100, are dedicated to two of the relay drivers.? If that's

I'll have to look at that.? I was thinking of doing the exact thing.? I want to have the ATU-100 send its current info (forward, reverse, power, etc.) out over a serial line to a raspberry Pi.?

Thanks, that's pretty much what I want to achieve. Wish it was being done on a Pi.....know nothing about Arduinos. Charlie

Florian Thienel has a way to do that.? See https://github.com/ftl/atu100wifi.? He has code for an Arduino Nano that pretends to be the display and sends the info over a serial line.? He then uses

Hi, Charlie. No, no those futures you need. But you can add them in firmware pretty easy.

Would it be possible to monitor the SWR and/or power metering via a serial port , or to control the tuner by a serial port ?? I run my radios all remotely, and with serial control, I could do that on

Well, I started removing the 0.1 uf SMD capacitors on the 12 volt bus.? The next-to-last one did the trick! Steve
