Re: Manual to set up uBitx Ver 6

Dennis Zabawa
 

Upon referencing the uBITXV6 Operations manual I noted the following: 

The radio switches automatically to LSB when operating below 10 MHz.

Can you force it to USB to allow for soundcard, digital modes of operation?

Hi!

Are you sure you want to sell it instead of calibrating the BFO? :-)

BFO calibration takes about 5 minutes with a USB sound card on your PC.

The setup is working as I was able to make some contacts with WSPR and also FT8 but I really have no time to go further for now.

Is your antenna resonant at the frequency you are listening to, or is it a random length of wire?

When first testing my uBITX v5 with a random antenna, I had all kinds of interference from local broadcast stations. Figured I would need to use a high-pass filter on the receiver. Then I changed to using my 40/80 m dipoles (parallel) and all the broadcast interference (BCI) disappeared. Ha! No HPF needed after all.

By the way, we are talking about AM broadcast interference, aren't we? Not "FM" as the subject line says?

Re: Let's Minimize the Library problems.

Jack, W8TEE
 

Tom:

I think you mean the tool chain developed by Roger Clark for the STM32. Most of Paul's work is dedicated to the Teensy family, which his company developed. Paul's Teensy 4.0 (aka T4) is a real game-changer.  Our book's DSP project does a real time FFT plot of the audio signal so you can see the impact of your DSP changes in real time. You can't do that without having a fast processor (e.g., the 600MHz clock of the T4).

The key to working with any graphics library is to make sure your display has the right video driver chip to match the library. If more people understood that, or if us programmers were more careful to use download URL's for the correct library in the code, there would be a lot less bandwidth used here. This is taken from the JackAl header file:

#include <Arduino.h>          // Standard with IDE
#include <EEPROM.h>           // EEPROM distributed with Teensy libraries
#include <math.h>             // Standard with IDE
#include <Wire.h>             // Standard with IDE
#include <SPI.h>              // Standard with IDE
#include <stdio.h>            // Standard with IDE

#include <OpenAudio_ArduinoLibrary.h> // http://hamradiodesigns.com/index.php/content/
#include <Adafruit_GFX.h>     // Now supplied with Teensy Library install
#include <Audio.h>            // Now supplied with Teensy Library install

As you can see, it is not hard to do and it makes it unequivocal which library to use.

Another big issue I've found, for example with the graphics/touchscreen libraries, is several libraries such as the Adafruit graphic libraries need to work together with the lower level display module drivers for the TFT and touchscreen hardware. 

Library writers upgrade and enhance their libraries and no regression tests are (or can be) done on other libraries compatibilities, especially the non-mainstream libraries like those for the Blue Pill. And writers of the STM32 libraries may not be maintaining their libraries anymore, so they don't get updated. 

For what ever reason, the ESP32 toolchain developers have been doing a much better job in keeping their libraries updated to reflect changes in other libraries they are dependent on.

In an example of trying to get a touchscreen display working on a Blue Pill, AdaFruit updated one of the screen attributes from one parameters to two. (I've forgotten which one, but they changed the X and Y parameters [possibility a dot size value] to be separately specified, rather than the X and Y values being equal.) There was no backwards compatibility so the STM32 touchscreen libraries no longer worked. The change was done in a way that adding simple wrappers, still required culling through the AdaFruit code to correct numerous instances in the code. (There were still other issues with the hardware assumptions around interrupts and SPI ports, that clashed in the latest libraries, but may not have in older libraries when the STM32 toolchains were first introduced, years earlier)

Unlike the ESP32 toolchain, the STM32 toolchain(s) seemed to get off to a bad start, along with libraries breaking over time as other libraries are updated, generating confusion and trouble it so far has not recovered from. Then adding two toolchains to top the confusion off. 

For many simpler projects, these issues are less troublesome and the Arduino platform is still simple fun to use.

Finally, I don't bother with putting boot loaders on the Blue Pills. I either flash the program with the serial boot loader built into the chip, with a USB to serial adaptor, or use one of the inexpensive ST-Link adaptor clones from eBay. Although I might try the various boot loaders out at some future point. I can see for something like the uBitx installing a USB boot loader would be the best way to go for usability. 

Whichever toolchain you use, as Jack pointed out, let people know where the actual source location of library you used can be found.  As, many libraries have more than one version and authors.

Hi Farhan,

I was just reading the post you did elsewhere and was impressed at the work you did to accomplish the user interface with such minimal resources. For the uBitx that is fantastic as it allows the folks that are building it to learn, to also delve into the software world without all the pain of using less stable toolchains and libraries. Cost is also important for your uBitx to have the reach of users around the world it is enjoying. So the path you went down is great. I'm definitely interested in looking at the code you wrote for creating the minimal resources needed user interface.

Re: V4 TX problems and new finals #ubitx-help

Evan Hand
 

Don,

The initial post states that you were able to follow the bias adjustment procedure correct?  And that you were able to adjust the bias resistors to get 100 ma increase for each IRF510.  That should pretty much eliminate them, the bias and connections through to the PA power supply.  

You have checked the other driver transistors and they seem to checkout as well.

At this point I would remove power from the rig
Look at R97 and R98 to verify that they are not open. 
Verify that TP7 is at ground to check the output coil on the output tranformere. 
Then without any power, verify that there is continuity from TP7 to TP8, followed by applying power to ONLY the main board (Red wire) and not the PA (Brown wire). 
Then select each band and verify connection from TP7 to TP8 with the key or PTT pressed. 

This is to verify that all of the relays are working, and that the inductors are not open.

That is the extent of what I can think of to test without an RF probe or oscilloscope.

There are RF probes that can be made with a few components.  Check out this web link:
http://n5ese.com/rfprobe1.htm

Let us know if the continuity checks play out.

Buddy,
All the user interface is usable without needing touch. If you tap on the tuning knob for a second, you can move the focus from one button to the next and then click in the button to select again. Each button has text associated with it that can be read out. I have taken care to see to it that all features are accessible with and without touch. For example, the ability to enter a new frequency using the touch pad is replicated in fast tune where if you hold down the button while on one of the vfos , you can now quickly move across the bands in 50 khz steps.

Jack,
The function names are confusing as well..many variables are declared and not used any more. There is a large amount of code that is commented out as well. I have to clean that up, refactor reassemble. I will hopefully do this after Christmas.
The graphics library should really be called just a user interface library. The ILI9341 uses a SPI interface where it can fill a rectangle with a 16-bit colour. I used this to draw vertical lines, horizontal lines and pixels. No other graphical primitives have been used. The text characters are plotted pixel by pixel. The entire graphics routines are less than 100 lines. An often reused routine is the drawText routine that draws text centered inside a rectangle with a border. That makes all the buttons trivial. Almost all the user interface is just buttons, very much inspired by the jackal.
While tuning, i observed that only one digit if the frequency read out changes most of the time. So, the displayVFO routines figures which digits need to be repainted and updates only those. This routine is probably what makes the interface usable with the 8 bit power of the Arduino Nano.
