Re: "RADUINO" Versions

Anyone happen to have a matrix of the various options ?? (silly question).

Kees: I have a great idea for a little project that will keep you out of trouble for a day or two...

Re: JackAl Board Debut

Art:

The JackAl board expects to see the display with the following profile:

Interface??????????????????? 4 wire SPI
Power supply type ??? 3.3V
Touch panel type?????? Resistive
SD card interface ???? Not used
Font chip?????????????????? ER33-4-1

We really don't need the special font chip and you can use the font supplied with the library. However, the chip is cheap enough we ordered them with the font chip above. The same is true for the 7" display. BuyDisplay.com has the following description at the bottom of the correct display:

????????ER-TFTM050-3 is 5 inch tft lcd module WVGA 800x480 display, serial, spi, i2c parallel interface,
??????? RA8875 controller, capacitive or resistive touch screen panel

This should help you order the correct display.

Re: "RADUINO" Versions

 

You also forgot KB1OIQ who went with I2C for display and added keypad and voice
output suitable for low/no vision operators.? Call that #9.

I'll be #10....
MIne I may or may not publish when done be the root is 4.3 and it will be a fork of that
with a very different UI.? ? The primary change is no rotary encoder, less or no menu,

Re: Raduino CAD Files

Sounds like you have a lot of good stuff...I'll have a look.?

I'm about 1/2 finished on a Raduino board using the Pill. I'm developing it in DipTrace, which I prefer over Eagle and KiKad. In any case, I think there are file converters. I leave on Sunday for a month long vacation, so nothing will realistically be coming from me until July.

Ground is ground all the way through.

Only exception might be if you try putting a bridge rectifier up front so it still
works if the wires are swapped.? ?Bad idea.

The fuse is an integral part of polarity protection if using a shunt diode.?

Some techs prefer to put the diode before the fuse as a practice to keep positive voltage off the ground plane.

Now the diode installed after the fuse will do the same but if you miswire anything after the fuse,then you will be holding a really neat looking paper weight. The diode only conducts one way and I personally have used this method to protect some of my equipment. A fuse is a fuse. Only protects from current. I prefer to protect my equipment from reverse polarity before it gets into the ground side. I do this because I have repaired many rigs with fuse first, and the owner hooked up the pwr source wrong. You can also wire it in series with ur power cord externally .some chips will fry before u get the display to glow. - 5 or - 12 is a whole lot of hurt to a static sensitive chip.

Before you start reviewing the code, let me give you a heads up of what to expect. Going by the general mood, I have taken the call to substantially borrow from Ian, KD8CEC's code and back port it to the original ubitx code. I guess that the new code has about 10% more lines but it is substantially more robust and useful.? The main features that I cherry picked from Ian's code are:

1. Keyer. You have to choose which keyer to use, but the keying is much better and robust now. This code is a total copy/paste of Ian's keyer. The auto-keyer (that sends out preset phrases in cw) is left out. The Iamabic A, Iambic B and the handkey sending works very well.
2. CAT control. Given the popularity of FT8, I rewrote the cat by following Ian's code but rewrote it to follow the ubitx coding conventions. It is a miminal set.
3. Split operations: My own interest of working with satellites have prompted me to add split operation.?
4. Rationalized menus: The menu system is now more consistent.
5. Tuning mechanism. The accelerated tuning works, though it doesn't jump randomly like before nor does it work at that speed. For very long band changes, it is recommended to do that through the menu option to change the band.

Among the things left out was support for different other types of displays, wspr beacon and many other goodies. The eeprom memory map is kept consistent with the KD8CEC's plan. You can switch between both the codes easily.

Al is the brains behind the filters, so I'll let him respond:


Thanks for the suggestion.? We have this sort of documentation ready for the user Manual, describing the filter topology, etc.? Our filters are based on digital BiQuad filters, which are sampled at 44.1Khz. This allows for a potential bandwidth of 22KHz.? While interesting for experimenters, this sort of detail is beyond normal marketing data.? We will be creating several articles and White Papers on the methods used once we get the product in production.? We will let everyone know when the material is ready.

Re: Raduino CAD Files

 

I've also been contemplating replacing the Nano with one of the STM32F103 "Blue Pill" Boards in the uBITX. I don't have the uBITX board dimensions but if you are interested I do have the Blue Pill board schematic icon and footprint in my public KiCAD repository at github.com/celeritous as well as schematic icons and footprints for several of the TFT displays with SPI interface.

I've also got an STM32F103 STM32CubeMX sample project in the repository as well as some other STM32 module boards that are released under the CERN OSH license. There is a 50mm x 50mm STM32F745 board with Ethernet interface, dual USB and uSD card and a low power STM32L151/152VDx processor? 50mm square board with USB abnd an optional uSD card and ESP07 WiFi module on it.? These both use 2 dual row 34 Pin 100 mil headers to bring out a lot of I/O. There are sample STM32CubeMX files with them.? There is also a 2.8" TFT LCD user interface board with 2 rotary encoders and 12 pushbutton array that I'm currently testing. It uses some passive and active de-bouncing so not a lot has to be done in software.

I'm also working on a board similar in size to the blue pill board that uses the STM32L152CCx processor which is lower power, 32MHz and has 256K of memory. It should be out in the next few days.? This is the one I was really intending to target the uBITX with. It was originally developed for a GPSDO project using the SIliabs SI534x Synthesizers with Holdover.? I've just been waiting on some enclosures from China to verify the size on everything before ordering some test boards.?

I should also have some STM32CubeMX? HAL compatible libraries for release soon for the ILI9341 and similar displays as well as the MCP23017 I2C digital IO expander and 25AA02 MAC EEPROM. I found most of the Adafruit ports to the STM32 lacking unless you use the Arduino environment.

We primarily use the STM32CubeMX to generate the initialization code and Atollic True Studio (Now free since ST acquired them) which is a good little development environment with actual hardware debugging. I've never really liked the Arduino and mBed style environment that don't provide for real hardware debugging.? I've been doing embedded design now for going on 40 years beginning with the Z80.

I hope that the more adventurous wanting to move to platforms with more than 32K of memory and faster speeds will find these of use. I did do some graphics tests with the ILI9341 driver and TFT displays on the blue pill boards and it is not hard to exceed the 64K (or even occasional 128K) memory on them with a few graphics and fonts.

Re: pin 2 of raduino board seems to have gone to CW TX full time after boot message.

 

.5% is not great accuracy, most crystals are 10x better and a heck of a lot more stable.
However for a CPU its about all you need.

I'll box up the Raduino as then radiated spurs have less a change to propagate.? If they
are not in a ham band I'll be very happy.? It is rare to find a radio without spurs causing
birdies even in the expensive commercial world.

The only way to avoid that in superhet radios is serious shielding, filtering,, and bypassing.?
That makes radios heavy and expensive.? The alternate is direct conversion image reject
architecture and that has headaches as well.
