Re: W8TEE TFT/ VFO DISPLAY BOARD BOARD
My bad...and stupid. If you changed the symbolic constants up near line 121 and 122, then use the following at lines 1415-1418
? ? ? ? ? if (flag == -1) { ? ? ? ? ? ? ? ? ? // Too low ? ? ? ? ? ? currentFrequency = VFOLOWERFREQUENCYLIMIT; ? ? ?// Set to min ? ? ? ? ? } else { ? ? ? ? ? ? currentFrequency = VFOUPPERFREQUENCYLIMIT ?; ? ? ?// Set to max ? ? ? ? ? }
That's the first stupid thing I've done since lunch...

The default is 7030 if no?EEPROM recorded before.
You maybe check the librarys as described in the?TFTVFOManual.
For checking the display, you can compile and run "graphictest_kbv" in the MCUFRIEND_kbv Directory.

Good luck and success! (and maybe a quick delivery of a new DDS...)

If you have a scope, connect it to OUT2 on the board. You should see a sine wave.

I expect speaker is ok, have tested it with a 1,5V batt. and it gives a " blob"?
everything have worked until I made a complete rewiring and connected parts for CW !
I do not use connectors instead I have solder wires from Raduino to Bitx40 board

W8TEE Table of MEGA 2560 Pro Mini pin assignments versus Allard's Nano pin assignments.
All:
I just uploaded a table that shows the pin assignments for my MEGA2560 Pro Mini TFT/VFO PCB versus Allard's Nano pin assignments as of his release 1.18 for the Raduino. Look for a file that starts with "W8TEE" and has "Table" in its description. I have tried to not conflict with any of Allard's pins. This means that you should be able to move some of the hardware/software features that Allard brings to the table without conflicting with the features that I have/will add to the code.

Re: - W8TEE board and pin connections
The PCB schematic has been posted, but I've reattached it here. If you look on the upper-left corner of the PCB, you will see OUT2 and GND (yellow header). That is the buffered output of the VFO and is the one I'm using for the BITX40. I'm using RG174 to route the signal to the BITX40 board. The set of pins next to it is labeled OUT below the header pins, which bypasses U2. If you locate C1 and C3 on the PCB, it's easy to see how they relate to the schematic. Because the AD9850 can produce a square wave, we brought that out to the set of pins at the right side of that header strip for anyone who might want to experiment with the board. The encoder pinouts for the Clock and Data lines are on the header to the right of the OUT's on the board and are silk screened (A = ?CLK, B = DAT, and S = SW). It's a little hard to see these in the photo, but look towards the center of the forest of header pins at the top. The 'S' is for the encoder switch. This assumes you are using an encoder with a switch (e.g., KY-040 family). Other than the output from the VFO and POWER, the rest of the connections are as the standard BITX40 works. If you want to use the CW features, TONEPIN is set to pin 11 and that needs to be connected to the speaker through a dropping resistor (e.g., 220-840 ohm). The TONEPIN is defined in the MorseCode.h header file which is part of the project. (I'm not happy with MorseCode.h as it contains function definitions, which properly belong in a *.cpp file.) ?If you disconnect power to the PA, you can use the B40 as a code practice oscillator. DITPIN and DAHPIN are currently set to pins 35 and 37 but may be changed if you want to move them somewhere else.?
Power to the board is supplied via the PWR pins visible in the lower-right corner of the board. It is assumed that the DC input voltage is 9-12V. That is routed through the VR_MINI_360 buck converter that you see silk screened onto the board. It supplies the voltage to the PCB, Mega 2560 Pro Mini, AD9850. The 5V-GND set appearing at the top-right of the board is taken from the Mega board, so don't exceed the power draw of the Mega. The board "plugs into" the TFT display, which would be "underneath" the board in the photo.
Right now I'm trying to make up an I/O pin assignment table showing Allard's pins versus my pins to insure they don't conflict. I cannot confirm this yet, but some of Allard's features should be able to be ported to my code, which is why I'm trying not to conflict with his code. Right now, I feel like the guy charged to drain the swamp while alligators are nipping at his butt. When I'm done, I'll likely move some of Allard's code into mine so there is a consistent code behind both with respect to the feature set.?
I hope this helps. Stay tuned...

How much current draws the entire board in operation?
My board takes ~300mA at 12,6V and I see a little brightness flicker on every operation on the display.
Is this normal?
The Testpoints voltage are OK.

Other that those for the encoder, the header I/O pins are not labeled. There's not enough pico acres on the PCB to do a good silk screen. Use a continuity tester from the Mega pin to a header pin to find out how they are mapped.
