Released EU1KY Antenna Analyzer Version 0.34 (Stabilized version from V0.30)

Released EU1KY Antenna Analyzer Version 0.34 (Stabilized version from V0.30)

Stabilized version V0.35 has been released, and stabilized version is posted separately.
Please download the latest stable version from the link below.
http://www.hamskey.com/2019/03/eu1ky-antenna-analyzer-cec-stabilized.html

The stable version will continue to be updated on the Link above.

----------------------
Version 0.34 is a stabilized version that resolves the issue of memory interference.
If you are using Version 0.30 or Version 0.33, be sure to upgrade to Version 0.34.




1.About Version 0.34
I launched Versoin 0.30 a few days ago and it was a memory interference issue.
There was a problem with inter-memory interference, and we released version 0.33 with an urgent fix.

It was determined that the compiler was in the process of linking. I have some suspicions and applied suspicious parts to the source code, and all of the memory interferences are gone.

Version 0.34 has the same function as Version 0.30, so please refer to the link below for the function.



2.Full Test and Stored Calibration file test for Version 0.34
Before I deploy, we have taken the following video in order to do full testing.
(You do not have to watch this video. There is nothing new. It was just taken to make sure it was stable again)

3.Download Firmware File
If you are using Version 0.30 or Version 0.33, please upgrade to 0.34.

  1. Hi, Ian!

    Now it works fine! S21 now stable to about 80 MHz
    A slight flicker at the bottom of the screen when moving the cursor in sweep mode is present but not annoying
    When working with an external program, there is no screen flickering.
    Thanks for your work!

      Wow, Great!
      I used the keil compiler mainly, and this time I used the embitz compiler. I am glad to have a little more understanding of the embitz compiler.

      And you have a perfect test.
      All right, In Sweep mode, the blinking of the text when I moved the cursor was what I did. Refresh the overlapping part because the button text is hidden by the cursor text.

      Thank you for your testing

    2. Hi, Ian!
      It would be interesting to try to add switching the output of the signal generator mode to the S21 port.

    3. Using the S2 port, we could increase the output a bit more.
      If so, this device would be a little more useful than the Antenna Analyzer.

  2. Hi Ian,

    The main menu I like and would like to use in another program. I would like to ask the source.

      If you need a menu in version 0.34, I'll put it up for you.

  3. hello ian

    im tested your sw 0.34 and make completly calibration ,the files wich are write AA on sd card is no more readble on pc it will format it if im want see wats on sd card also my logo start pickture is owerwriten .

      The SD card is frequently damaged in the STM32F746. In particular, if the power supply to the STM32F746 is unstable, it is often the case that the sector is lost.

      If I get a chance later, I will post an article about this.

      I recommend using the SD-Card Wipe tool. If you wipe your SD card, you will be able to reformat it.

      I have not yet modified the Read Write Library for the SD-Card, but I will try to find out if there is a better library.

      Can you tell me what devices are connected to the STM32F746 board?
      I think it will be a lot of help if you let me know what the power source is.

      I'm doing various tests now, testing the firmware from all versions of the eu1ky firmware, and looking at the fat related libraries.
      I'm also experimenting with the latest fat libraries, probably in version 0.36, which is stable with respect to the SD-Card.
      Can you test again when the 0.36 is released?

      It's probably because your SD-Card is damaged.
      Because of you now, I think I have found the best way to use SD-Cards safely. Please wait a day or two. I will add SD-Card protection more stable than any other version.
      I'm adding a SD-card stress program to the firmware and I'm still simulating it, and I think I found a good way to write 100,000 OSL data.
      I will proceed with the test a bit more carefully and apply the best method.

      Thank you for giving me the results of various tests.
      I have studied a lot of FAT libraries and STM's HAL libraries thanks to you.
      And I had a very good study.

      Wait a few days.

    2. Hi, Ian!
      I'm also waiting for the software update because encountered calibration save errors again.
      I noticed that the calibration is lost if the screen blinks at the moment of saving the calibration. It is necessary to catch the moment when it does not blink and then save :D

    3. I experimented with several SD-cards and peripherals. I found a conflict between the STM32F746 board and the fat Library.
      Maybe we can find a fairly secure way.
      I am experimenting with my STM32F746 board in the worst condition. (Many additional devices, equipped with devices that can interfere with communication)

      Please wait some days.

  5. Hello from Greece - SV1BTA. Please let me ask you this: I have been in the MINI 1300 version 0.35 for 2 months now and as I saw on the RF frontend board there are no bridges in the H / W and Work positions. There is a short circuit in the Work contacts and I am really worried about whether this is right or not. As I've read in your instructions for proper calibration we have to switch to H / W and Work every time. Is that right or not in the end? Do I have to reset the bridges as shown in the instructions or not? Isn't it necessary for bridges in version 0.35? Please let me know what is wrong with me to make sure that the MINI 1300 is working properly.

uBITX with Nextion LCD (CEC Firmware) - Installation and Introduction

uBITX with Nextion LCD (CEC Firmware) - Installation and Introduction uBITX CEC Firmware supports various LCD since Version 1.08 (16x02 Parallel, 20x04 Parallel, 16x02  I2C, 20x04 I2C, 16x02 Dual LCD with I2C).
Supports Nextion LCD (Graphic LCD) from Version 1.09, Version 1.09x is primarily aimed at Nextion LCD support. Also 1.09x will continue to be Beta version. If you want a stable version, please use 1.08 or 1.1 version to be released in the future.

uBITX Firmware CEC Version 1.1 Release

uBITX Firmware CEC Version 1.1 Release
Version 1.1 is the first major release since 1.097, I will release it after a 50-day beta test.


Version 1.1 includes all additions or improvements from 1.08 to 1.09, 1.093, 1.095, 1.097 

How to upgrade uBITX Firmware

uBITX is based on Arduino Nano. So uBITX's firmware upgrade method is the same as Arduino.
There are two ways to upgrade the firmware of uBITX.

The first is to compile the source from the Arduino IDE, and the second is to upload the compiled hex file using the Firmware Upgrade Tool.

I'll show you how to upload a compiled hex file as a second method.

1.Connect the uBITX's USB cable to the computer.


2.Run Device Manager on your computer.
  The way to open the Device Manager for each OS Version differs slightly.
  In most Windows, you can easily launch the Device Manager by running.

  On your computer, press the Windows key + R.



 Type devmgmt.msc and press OK Button.




On most operating systems, there will be a serial port named Ports with CH340. If so, the next step is skipped.

If the serial port is not installed as below, you need to install the driver.



Included in uBITX is the Adonano, which uses the CH340 USB To UART part.

Download the latest CH340 driver from the Internet.
