The platform most Arduino Blue Pill projects are still done with. Maybe the work the people have done with the Teensy make it one of the best places to start, if you want to use STM32 and other more powerful boards with Arduino. As they are smart to focus on a set of boards that they build and have control over, and therefore can support with stable working toolchains and libraries. Looks like the way they have kept their boards form being crushed by cheap clones, and afford to stay in business, is they have a special bootloader chip they keep?proprietary. I may buy some Teensy boards, do development on them, then when I want a new hair raising adventure I can try porting to a Blue Pill if cost is an issue. Mostly I do my STM32 development with the STM32Cube tools from STM now. Great for the consulting I do, but still want to do some projects on the Arduino platform so they can be shared in the Maker/hobbyist, open source community. Mbed is another interesting developer platform that is meant for both professional and Maker/hobbyist projects. Tom, wb6b |

Re: How to get rid of Local FM broadcast stations
#ubitx
Gavin,
As you said both the the station are 5 1/2 miles and they have AM counterparts. I am not sure if they are running the same shows on AM also because I feel you are picking up the AM signals.? ? Since you are getting it everywhere and as Farhan said it could be getting picked up by audio circuit. I would have taken out the LM386 chip from the socket and check the pins make them straight and push it back gently into the socket. I hope that helps. 73 Anthony VU3JVX |

Re: How to get rid of Local FM broadcast stations

Gavin
hang in there a bit and solve this one, its quite unusual.? I assume that your antenna has to be connected to hear these stations? if you happen to have any other power supply (even a gel cell battery), try to see if you still get interference.? I don't recall you answered how close these stations are?? As Farhan mentioned, check those connections to your volume control.? I think you mentioned these stations appear wherever the ubitx is tuned?? I am also assuming you have successfully used that antenna (I have an EFHW here also) with another rig?? I can presume any antenna fault that would cause this issue, but asking anyway.? In your photos - I see 2 very unusual coils of wire that maybe you made to try to neaten the arrangement.? I suggest straight runs of wire at the edge of the case - possibly you made yourself a transformer feeding this interference.? try touching each of these coils to see if it goes away.? sometimes careful use of your finger can help with troubleshooting - just don't do this in high voltage tube or AC power supply circuits.?

Re: ubitx V5 assembled + battery + accessories to sell
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. -adrian On Sun, 15 Dec 2019 at 03:32, Adrien F4IJA <adrien.grelet@...> wrote: Hi all, |

Any other ideas why its picking up these local stations?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? 73, ... Martin VE3OAT |

Re: Frequency calibration V5
So i picked up one of those NanoVNA¡¯s on amazon and it can generate a constant signal on any given frequency.? I¡¯m wondering how I can use that to set the BFO / calibration.??

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 #include <RA8875.h>?????????? // http://hamradiodesigns.com/index.php/content/ #include <Rotary.h>?????????? // https://github.com/brianlow/Rotary #include <SerialFlash.h>????? // Now supplied with Teensy Library install #include <Time.h>???????????? // Now supplied with Teensy Library install #include <TimeLib.h>????????? // Now supplied with Teensy Library install #include <TimerOne.h>???????? // Now supplied with Teensy Library install #include <UTFT.h>???????????? // Now supplied with Teensy Library install #include <URTouch.h>????????? // http://www.rinkydinkelectronics.com/library.php?id=92 #include <UTFT_Buttons.h>???? // http://www.rinkydinkelectronics.com/library.php?id=61 As you can see, it is not hard to do and it makes it unequivocal which library to use. Jack, W8TEE P.S. Now that the book's done, Al and I are going to resurrect our hamradiodesigns web site. It's been hacked, so don't go there now. For the moment, most of the files have been moved to my softwarecontrolledhamradio web site.

I would prefer the official STM32 toolchain, but most Arduino Blue Pill projects seem to have been developed with the Paul Stoffregen version, so I use it.? 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.

ubitx V5 assembled + battery + accessories to sell
Adrien F4IJA
Hi all,
I've bought a V5 board some months ago, I assembled it in a custom case with a good battery pack, connectors, etc etc. I've well set up the frequency calibration (see there :?) But now I need to calibrate finely the BFO and I really have no time (we bought a house and I've a company to run...) Instead of leaving this board unused I'd like to sell it to someone who wants a fresh start with an already assembled board. 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. I propose the complete system with : V5 board with stock LCD screen the battery pack the whole box (3d printed and CNC milled for the plates) the connectors, etc etc. the battery pack charger You can see the project and the build here :?/g/BITX20/topic/project_ubitx_go_box_with/33030891?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,33030891 I propose 200€ for this + shipping depending on where you are. The price can be negociable, just please be honest and respectful. Looking forward for your contacts ! -- 73's Adrien F4IJA |

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.? Tom, wb6b |

Evan, Mark, Raj, Anthony, & Co.
What is marveling about this lovely radio is its resilienance to stupidity. What is marveling about this community is how unbelievably kind, helpful, generous and talented you people are. How many times did I turn the bias pots the wrong way? Counter what? And the driver adjustment does what which way?? Why does the uBITX go dark and reset when my DVM probe slips and shorts the? IRF510 pins?? Which pin is the gate (again?)?? Why does my uBITX go all Chernobyl when I put 2Ov on the PA brown wire and fail to notice that I'm stuck in TX? WSPR digital mode 100% duty cycle for 10 minutes with way too much drive? Why didn't I study electronics in school? Okay there were way more girls in English class, but still...it would be sort of useful around now... I have to draw little cute diagrams of transistors and label them because I can never remember what lead is what. I feel like a first grader learning how to tie their shoes.? If I set the bias current drain, then the voltage on the gate can't be zero.? Ah....so there is an error here...wait...is this that well meaning dope Don?? Good grief, he? can't get him out the door if you pushed him -- electrically. Hahah. And I always feared that my problem (s?) are due to "operator error". I seem to have lots of that. Hahaha.? ? uBITX? is just humility spelled backwards.? It is sooooo much better and smarter than I am.? But, that makes it really fruitful to study and poke and add to.? I'll get back to Lab Class and report out on the "Rs" and the "TPs" and the counter clock wise what? Hahah. Thanks a hundred million. Don |

Re: Let's Minimize the Library problems.
Tom, I have moved on to using nothing except the standard arduino libraries. The current build is dependent only in the i2c and spi libraries. I am going bare metal on the touch library as well. I will oush the touch and display code into one file that you can rewrite for every display. - f On Sun 15 Dec, 2019, 10:14 AM Tom, wb6b, <wb6b@...> wrote: Perhaps the biggest problem with STM32F103 Blue Pill development on the Arduino platform is there are two competing tool chains, the original "Paul Stoffregen" toolchain and the "official" STM32 tool chain endorsed by STM.
