Thanks, I've downloaded the code file and will be studying it. ?I had considered a hardware keyer (that's the easy way), but wanted the Arduino keyer so the code speed could be displayed on LCD.

I just shared a link to the sketch for the Canned Frog.

Thanks for the info - I'll be looking into the sources ya'll gave. ?

When I did the Canned Frog last year I added a simple keyer to the software. For speed control, I used the rotary encoder with the push button pressed to change speed.

Hi Jack.

Thanks for pointing that mod out.
I have had to do it before, mostly when I was playing with PIC programming.
I really should do it as a matter of course with rotary encoders generally - I must be getting old.
Oh yes - I forgot - I am old HI!

I thought this might be of interest to the group.
I have been using different rotary encoders over the years for diferent projects and perhaps the following info may be of help.

I have included a photo of the type I am referring to as "rotary encoder.jpg" in the files section.

It is marked with the name 'KEYES' but can be found 'unbranded' on several Chinese sites. To the UK they come in at less than ?4 for 10 of them.

The encoder on this pcb requires a 5V supply and will not work simply with reference to the digital input levels on the Arduino pins.

The connections needed for it to work are as follows, referring to the print on the encoder pcb and the print on the multiway connector on the project motherboard.

CLK --> pin marked 2 on board (yellow section of pins)
DT ----> pin marked 3 on board (yellow section of pins)
SW ---> pin marked 7 on board (yellow section of pins)
?+? -----)> 5V (any one will do)
GND -----> G (any one will do)

all the best

I may have missed someone already giving this advice, if I have I apologise.

Not all the I2C displays out there are pin for pin compatible.

Also the I2C address is very important.

50% of the display driver boards and LCDs I have come across use the 0x27 base address as in the original arduino sketch for this project.
However the other common I2C LCD display boards I have use address 0x20.

Unfortunately simply changing the I2C address to 0x20 instead of 0x27 doesn't make them work.

This is because the pins utilised on the PCF9574 I2C control chip to drive the display are different for different driver board manufacturers.

I currently am using the 0x27 boards that have a link on one end of the board to disable the backlight and they work perfectly in the sketch

If you are using boards from Alioexpress (or other Chinese suppliers) that have 'IICLCD' printed on the board they are 0x20 base address boards and the sketch will need a bit of work in the "LiquidCrystal_I2C lcd () " statement to make them function.

This is the line I use for my I2C 0X20 boards from Aliexpress

LiquidCrystal_I2C lcd (0x20, 4, 5, 6, 0, 1, 2, 3, 7, NEGATIVE);

You may need to change NEGATIVE to POSITIVE depending on how you find the display backlight functions.

I hope that may help someone

Hank / K5HDE,
Jack / W8TEE,

I just finished assembly of Forty-9er/Nano/DDS/16x2 LCD/Encoder. Finally got the VfoSource sketch to compile but LCD only back lights and has the top row of matrix squares lighted (No alpha-numeric). I'm using a 16x2 LCD display (Chinese 1602A Ver2.0) with a piggyback I2C serial converter board (Type 1, A0, A1, A2) I soldered to LCD. I ran the suggested address scanner and got: Found Address 63 (0x3F).? I notice that the VfoSource sketch,? line 100, addresses: lcd (0x27, 16, 2);

Hank, I'm guessing that this is similar to your initial LCD problem. I downloaded the NewliquidCrystal_1.3.4.zip files but there seems to be a load of different .cpp and .h library files to choose from for various LCDs.

I'm? stuck...

Great! ?Thanks Bud, I'll get it. ?I think that was one of the hits I had when I was searching for the header file.
