requires you to install the STM32F patch
Hi, I planning on using this STM32 ARM board manager. This 32 bit ARM extension for Arduino is written by actual ST Microelectronics software engineers. It looks like it is based on the same libraries used in their?STM32Cube (hopefully wrapped with all the same Arduino libraries Arduino people are familiar with). Unlike their professional development tools, the Arduino version also works for generic boards like the Blue Pill. For the Blue Pill it has a serial up-load option. I haven't tested it on a Blue Pill, but hopefully that means working with the standard boot loader that comes on the Blue Pill boards.? To install this STM32 board tool chain, go to the Arduino preferences and add the following URL to the "Additional Board Manager URL's" box: The Morse Code Tutor is a cool project, however I might use a?NUCLEO-F303K8 development board because I have one in hand (they also have a board with the same chip as the Blue Pill. But I like the F303 because it has a built in Op-Amp(s) that can be used with the A2D converters). A cool thing about the Nucleo boards is you don't need a boot loader on the chip. The board has a second microprocessor chip that is an ST-Link programmer that programs the chip directly, without needing a boot loader, and debugger that lets you set break points and single step through your code. ?And you don't need to select a USB serial port for ST-Link to connect.?Even more cool is when you plug the board into your USB connector it emulates a USB thumb drive. You can just drag a hex file into the drive and it will flash the code into the microprocessor chip. The board costs $10 rather than $3 but are still a good value.? Here is a Getting started page: Here is a link to the board: A caveat. I have been using the ST Microelectronics development tools for STM32 (ARM) processors. It was only after seeing Jack's Code Tutor project that I looked to see what support there was for Arduino. I was very pleasantly surprised to see this tool chain. However, I have not tested it out to any extent or compiled Jack's Code Tutor yet. But, barring some unforeseen glitch I expect this to be a good library with the benefit that it is built on the same libraries I currently use.? That's my vote. Interested if others have tried this or other board tool sets that they like. Tom, wb6b

Re: Raduino frozen on BITX40
In case we are lucky, you need to bootload the arduino with so called Nano "old bootloader" ?. Later try LOADING ITX40 SKETCH FRESH. ?LET US SEE WHAT HAPPENS. ? Sorry for all caps.

Hello guys!
I nead help for my Raduion problem..
My BITX40 arrived and it was functioning fine. While I was waiting for enclosure to arrive I started to implement some mods to make it better suitable. In this process I accidentally made short circuit on Raduino board (not on Arduino but on other bigger board). It shorted between input from DDS port on main board (bringing +4.3V)? to Si5153 path , probably arround C4,C5 or C6 on Raduino to pins 6-10 of Si5153. In that very moment I lost RX (went very low, not quite dead) and LCD just blinked living only Raduino version written on. Tuning was lost and restart several times brought no change.
Suspecting Raduino/Arduino frozen I disconnect it totally and put to PC an installed (successfully!) the last sketch v.1.28.1. Therefore I think Arduino seamed to work fine, blinking all LEDs as it sholud (rx,tx and so on)..
But, when connected back to BITX board all problems remain:
1. no tuning,
2. low RX,
3. LCD just frozen showing Raduino vesion
4. If I disconnect Raduino from the main board DDS connector, nothing changes also!
5. When turning tuning put, only one LED is fixed light on Raduino (think one should blink when pot turning)
6. LM7805 on Raduino shows 12V and 5V fine, but it is to hot to touch, looks more than before..
7. All transistors on main board BITX show good voltages (checked!)
8. I do not hear 4MHz oscilator on neighbour receiver.. (should I..)
9. When I touch the base of Q8 I get stronger RX but I suspect that is not the main issue here..
Is my Si5153 dead and what to do..?

This is interesting. There could be two possible explanations: 1. There is gain compression. This is possible due to the two stage IF amplifiers. 2. The step attenuator is off-calibration.
One way to know is to measure readings of smaller attenuations at different attenuations. For instance how does the readings change between -50db and -53db as opposed to -10 and -13 db? My tests show quite linear relationship between actual attenation and db readings.

Re: Nextion 5/Enhanced for KD8CEC 1.2?
Also I think the Spectrum Analyzer page needs more work actually even the band analyzer. I may have been able to adjust their position and lengths of the analyzer graphs but the slider does not seem to work right with the scanned range. ?

The GitHub "5" appears to be a 2.8(?). (Upper left corner small image)

I don¡¯t recommend installing the Arduino IDE with sudo apt install command. You usually get a really old version from the distribution repositories. Something like version 1.0.5. Better download the version from Arduino website which at the moment is 1.8.9.

Hi,
If the program you are trying to port has a traditional C main routine and it starts out by doing init stuff then finally has a while loop, like 'while(1){ --lines of code--};.
Then put the stuff before the while loop into the "setup" routine. Put the stuff inside the while loop into the "loop" routine.
The only reason not to put everything into the "setup" routine is the "loop" routine allows the Arduino code, automatically included in addition to your code, to handle the serial I/O background processing for the print and get statements used to sent debug messages to a serial terminal. And likely other tasks that need to be done.?
Using the "loop" routine rather than your own while loop lets these routines to get a chance to run every cycle through your code.
If your code does not use a while loop (and is not already an Arduino program using the "loop" routine, then your code may be a higher level of coding using interrupts or a real time "operating" system. In that case everything is going to go in the "setup" routine and the "loop" routine need to be there but can be empty. However, porting that kind of code to the Arduino system may be beyond what the Arduino system was built for.
There are some Arduino libraries like "SoftTimer" ?that give some of the same feel to program in as a real interrupt driven RTOS. When using this library, for example, you put the things your program does in separate routines, rather than a big loop of code, and leave the "loop" routine empty.

Godz wotta pikki system! Won't even look at anything with non-alphanumeric name!? Anything with "_" is ignored.
The IDE recognizes the raduino when it's plugged in - and that powers it up. I not ~/sketchbook has been created, with subdir 'libraries' - empty except a redir txt to somewhere to learn abot installing libraries.
Anyone in NZ want to take way this box of junk?

Hi Dexter,
I have some questions regarding your setup. Maybe they are stupid and you already have done all these things, but the thread doesn't tell me what ?previously was done and what exactly was the (error) output. So here are my questions:?
- Which version of the Arduino IDE are you using??
- Which version of the ubitx software did you clone from github??
- Have you been able to compile one of the sample programs, or the minimal sketch (named like ?e.g. sketch_may21a) ?which is automatically created when ?selecting "File new"?
- If you open "File -> Preferences" Which path is shown under "Sketchbook location" e.g. /home/pi/Arduino?
- If you look into above directory is there a sub directory named ubitx_20 with a lot of?
- If yes, could you open in Arduino IDE the file ubitx_20.ino in this subdirectory??
- If yes, could you close all other Arduino windows except the ubitx_20 one you just opened?
Hopefully your answers will help to find the problem.

As other have said it seems the BFO. You probably need to shift by at least 500hz. This picture is very similar to the one I showed to a professional vendor when I bought from them a 'fully aligned' transceiver ... they gave me money back... I am still wondering what that full meant...
Il 21/mag/2019 18:34, "Curt via Groups.Io" <wb8yyy= [email protected]> ha scritto: Daniel YO8UFO op
Likewise I am thinking it could be your BFO setting - mine was way off when first delivered.? If you listen carefully to SSB you might come to same conclusion that it may need an adjustment.? Instructions are available at HFSignals - BFO adjustment tends to be easier than frequency calibration.? also see this guide at my local club:
??? ubitx calibration INSTRUCTIONS
Raj also brought up the topic of spurious - I have a v4 also.? In a typical v4 there are spurious issues in some of the bands, generally not much more than 10 dB out of compliance.? In mine I installed a circuit board containing a set of 3 relays, to separate input and output relay function.? it fixes spurious at 18 MHz and below (unfortunately the board and kit are not for sale anywhere yet!? I have dropped hints to ubitx 'merchants' to sell it).? my rig was okay 'as delivered' on 80 and 20 meters.? (I have not yet solved spurious above 18 MHz - they are from a different source - Raj I remember uses better relays and some shielded inductors - I am not sure what else.? I am wondering how the shielded inductors will work in conjunction with my relay solution - I need to get some to find out!? other fixes did not work for me without reducing CW output power).?
Enjoy your ubitx - I recommend 20 and 80 meters from what I have experienced with my rig for spurious. ??

Re: Antuino - the antenna analyzer
I slapped one together on the bench and used 69mhz filters salvaged out of a really dead
TS830 instead of the crystals for the filters.? Tweaked the code and works well.
Currently I'm experimenting with a replacement for the detector using a 1khz (really 1000 cycles)
low pass amplifier as that would allow a greater frequency range than 69mhz filter.
