Re: No display

Erik.  I changed the code per the manual.  here it is.

//Depending on the type of LCD mounted on the uBITX, uncomment one of the options below.
//You must select only one.
//#define UBITX_DISPLAY_LCD1602P      //LCD mounted on unmodified uBITX
#define UBITX_DISPLAY_LCD1602I      //I2C type 16 x 02 LCD
//#define UBITX_DISPLAY_LCD2004P      //24 x 04 LCD (Parallel)
//#define UBITX_DISPLAY_LCD2004I        //I2C type 24 x 04

This is in the portion marked ubitx.h

Is there something else I need to modify in the CECFW?


Re: v5 board original FW

Evan Hand
 

The only one that I know of is the GitHub repository where Ashhar keeps the source files:

https://github.com/afarhan/ubitx_v5/

All of the .ino files are required in the same directory to use the Arduino IDE to compile and then download the program.  I have not done this myself, so there may be some tricks that are required.

Note: the version 4 software will not work with the version 5 board.  HF Signals still needs some more updates to their web page, as the software link still points to the version 4 GitHub repository.  Would also be nice to have a .hex compiled version available for those who do not want to go through the difficulties of the IDE.

Hope this helps, though you may want to wait for others to chime in before moving forward.

v5 board original FW

Can someone send me a copy of the original radio FW for a V5 board or a location that I can find it. I read, I had ideas, I thought I knew what I was doing, it's gone and now I just want to get the radio working.
Thanks

As you have probably figured out, the schematic for the Bitx40 is at the top of this page:
    http://www.hfsignals.com/index.php/2017/11/23/bitx40-circuit-description/
and the assembly instructions here:
    http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/

The diagram at the top of the assembly instructions looks sort of like a photograph,
but it is instead computer generated from a board layout program and so
some of the parts and connectors do not look quite right. 

The diagram shows the Raduino oriented such that the display would be facing you,
but the display has been removed, and the diagram does not bother to include
the 16 pin display connector on the upper left.

The connector you are asking about is on the bottom.
Pin 1 is on square pin on the far right side, the diagram shows orange, red,
brown and black wires coming from that connector on pins 15,14,13,12.
The yellow wire from pin 16 is not used, but put tape over the end of it because
it will have 12 volts on it and you definitely don't want that touching anything else.

The early Bitx40 kits had a 5 pin connector on the back of the board (as shown in
the pictorial diagram) for that connector for pins 16,15,14,13,12, and we would 
then plug in a wiring harness to that connector with yellow, orange,red,brown,black
wires coming out of it.

But now the uBitx has come out, and for the uBitx all 16 pins of that connector
plug directly into the uBitx main board without any wiring harness.  
All Raduinos now get built the same, so all Raduinos have 16 right angle pins
soldered into the back of the Raduino there instead of the old 5 pin connector.
When using such a Raduino on a Bitx40, you should plug in the 5 wire harness
on pins 16,15,14,13,12 of those right angle header pins, it will mate perfectly well.
The unused yellow wire should be on pin 16, which is the furthest left in the pictorial diagram.

The Raduino first shipped in Dec of 2016, all Raduinos ever shipped since then
have been physically identical except for that connector.  

Raduinos shipped with a Bitx40 have Bitx40 firmware programmed into them.
this is different from the firmware on a Raduino that gets shipped with a uBitx.

Jerry, KE7ER



But it is correct, once you get the raduino board oriented correctly.
You are looking at a raduino board that has the display removed,
and the 16 pin display connector is on the upper left.
You should be able to see the

Just received a new Bitx40 kit.  In looking at the wiring instructions I have a question. There is a connector-8pin on one side of the board and another set of pins-16pins on the other side of the board bent at a 90° angle pointing up.  Does anything connect to these pins and if so, what kind of connector?  Also where is the #1 pin on this row of pins.  I also want to add a function switch.  All the pictures I have seen do not show this type of board. I got this kit straight from HF SIGNALS.

Check the adjustment instructions at HFsignals, but this sounds correct from memory  for ssb with no audio input. The current should go much higher when applying enough audio or doing cw. Unless you have a key, use a piece of wire to short the cw input to check your transmit current and output power.

Thanks, Sam. Now, I have no special attachment to the pictures, as this was someone else's program anyway :)   I'll put this on a screen and give it some exercise.

The S-meter hasn't been hooked up yet on this build though it will be.  Regarding art design, a tiny mushroom cloud would be a nice touch for signals above +20.

Re: No display

Verify the software loaded has the correct display set. If you loaded it from the IDE, there are several defines for the different types of supported displays. Make sure you have the right one selected before compiling the project.

Re: separate CAT jack, without using the USB cable #ubitx #cat #raduino #arduino

Gary Anderson
 

Sascha,
Basic question.  How do you have the RX/TX signals wired from Teensy to the Nano?
Teensy RX to Nano TX, Teensy TX to Nano RX?

Regards,
Gary


Re: separate CAT jack, without using the USB cable #ubitx #cat #raduino #arduino

John (vk2eta)
 

Hello Sascha,

Useful measurements. The issue is that your Arduino RX input is not pulled low enough (rather than not high enough).

I had a look at the Sparkfun logic converter that seems identical to what you used and it relies on the low voltage (3.3V) input pulling the voltage down which then passed through a mosfet transistor.

Therefore if the TX output of your loop controller can't pull the voltage low enough it has no chance to do so through the voltage converter. It would be ok if it was two inverting common emitter npn transistors circuits but it is not designed like that.

I also checked the circuit diagram of the loop controller and it has two 1K resistors on the RX and TX lines at the TTL input/output the Teensy.

So I recommend that you keep the voltage adapter in line as you have now, leave the Raduino/Arduino circuits as-is and remove (short circuit) the 1K resistor that is in series with the TX1 pin of the Teensy in the loop controller. This should then allow for a better drive of your voltage converter input and consequently of the input of the Arduino. You can leave the 1K resistor that goes to the Teensy's RX line.

At present I strongly suspect that the issue is that the 1K resistor in the loop controller circuit, is connected in effect in series with the 1K resistor between the Arduino RX line and the USB controller, and it does not allow the voltage to swing enough and that explains the difference in the low value (TTL logical one) between a powered up and an un-powered Arduino.

Hope that makes sense.

All the best,

73, John (VK2ETA)
