V6 radino on V5 board?

A Kiddoo <kt0tt.ham@...>
 

Will it be possible to purchase a V6 Radino only and adapt it to a V5 main board? Could this be a possible future upgrade path? Inquiring minds want to know.

So the answer is yes, you can update a v5 to have a v6 style display.
No need to swap out the entire Raduino, just the display itself.
Then burn the v6 firmware into the Nano.

I believe the Raduino board has not changed since first introduced for the Bitx40,
except that now a socket is used on the Nano to make it easier to replace.

The old 2x16 display just plugs in, hopefully the new display can plug into
that same old connector with no soldering necessary.

In the past, it has been possible to buy a Raduino separately from hfsignals for about $30.
I don't see that as an option on hfsignals.com now, the only items to buy are the complete v6 uBitx and the Antuino.
But if the display is easy to swap out, and the Nano is socketed and thus easy to replace if it fails,
that covers most of why you would want a new Raduino. 
About the only other stuff on the Raduino is connectors, LM7805 regulator, and the si5351.
If you really do need a new Raduino there have been third parties posting to the forum
offering their own version for sale, some of them with significant enhancements.

I am software but the wiring of the LCD connector is totally
different between V5 and V6.

Yes. V6 doesn't use an LCD at all. It uses one of the 2.8" TFT color screens and the pinouts go to a 14 pin connector that's mounted down the right side of the V6 Raduino board. V6 Raduino is the same size and has the same mounting holes as the 2.8" ILI9341 display they (and we) use.

If his schematic for the V6 is right, the pinouts for the Display (they are all available on the old 16 pin LCD connector)

I can't get a NANO (with Farhan's factory code) to boot to the 2.8" display (same one they used). Your code doesn't boot to the display either either in a Teensy 4 or NANO. I tried it on both a Raduino clone of ours and a real Raduino (the one from the V5 board you gave me). Neither work.

Signals from the display and where they are supposed to go according to the Raduino schematic:
1 -- VCC +5V to +5 on the Raduino
2 -- GND to GND on the Raduino
3 -- CS to D10 on the NANO or Teensy
4 -- RESET tied to +5
5 -- D_C to D9 on the NANO or Teensy
6 -- SDI/MOSI to D11 on the NANO/Teensy
7 -- SCK to D13 on the NANO/Teensy
8 -- LED to +5 for full brightness or through 22 ohm resistor for less brightnexx
9 -- SDO/MISO to D12 on the NANO/Teensy
10 -- T-CLK (parallel with SCK) to D13
11 -- T_CS to D8 on NANO/Teensy
12 -- T_DIN parallel with MOSI
13 -- T_DO parallel with MISO
14 -- T_IRQ not used leave open

I had previously written:

Wrong.  The connector from Raduino into the display is different, has 14 pins instead of 16 for starters.
Power and ground have moved so attempting to plug a 2.8" TFT into the old Raduino will smoke something.

The new v6 Raduino is a differerent PC Board layout to accommodate the different display connector.
Using the new TFT display with the old Raduino might be possible, but will require a dozen or so wires 
from old Raduino to display.

There are also differences in the "CONTROL" connector.  This means you need to rewire that connector as well.  The only connector on the v6 Raduino that has not changed from the v4/5 is the "OSCILLATORS" connector.

I noticed that too. The "CONTROL" connectors on the v5 and v6 appear to be reversed. Ill check this when i get a chance. Apart from that ,a quick glance at the schematics for both, the only differences i noticed were the TFT wiring plus the keyer and ptt lines from the main board to the raduino. 
Anyone managed to get the TFT working on their V5 yet?

On V6, the connector to the digital board has two extra pins. These don't disturb the original configuration of the original connecotor, they bring the keyer pin and the ptt to the main board to be routed to the keyer and the mic connectors. You could still plug in an old 16x2 LCD raduino into the new v6 main board and it will work all the same.
Now, about running the v6 firmware on v5 board, you will have to jumper gnd, 5v and the six data lines between the old raduino and a tft 2.8 inch display. I will post the pictures soon. The firmware for v6 will work for v5 board as long as you have connected am ili9341 tft display with touch on it.

Thanks for clarifying that Ashhar, i thought that was how it was configured. My display should be here today so i can jumper the tft screen to the old board and try it .
Thanks again

I thought I saw a difference in the Digital connector wiring on the new v6 Raduino.  If so, will need to rewire that connector as well.

I think the control cables are the same but the pin numbering for them have been reversed by mistake by Farhan in the v6 schematic. Ill figure this out when i get time to put screen in. Or ill check v5 and v6 code for the pin assignments that would tell if they are the same.
