Your post definitely reflects a motivation when it comes to constructing an oscilloscope. How about making an investment and getting on in return. I seem to recall a RoadTest PICOSCOPE 5444D MSO - USB Oscilloscope that I would encourage you to consider applying for.

I need to try this. Awesome job but can you fix the broken link please ?

The link given for spfd5408 is broken. Someone please send the ino sketch for the spfd5408 screen.

Can u please give circuit diagram to how to connect 2.4TFT to ARDUINO MEGA 2560. We connected it as u showed like shield but it shows only white screen and not display was seen. When i tested it in ARDUINO UNO then it worked well but problem is only with ARDUINO MEGA(i even added that #include mega_2560 in swift.cpp .). Please give me the circuit diagram to connect tft 2.4 to ARDUINO MEGA.

I think so, but mine it isn't used like that, with the touscreen, may e in the near future i'll configure the buttons to be shown on the display and to use the touch for that:p

Is it possible to use the toughscreen of the display (LCD has it) to get easier to handle?

Thank you for the pictures.

Hy everyone,

I managed to take some pictures of my setup, i will try the threshold modification for the switches in a couple of days.

Also i am planning to measures the resistance of the hole PCB( if CH0 button is pressed, which resistance does the mega measure). I am planning to convert that voltage into the resolution seen by the mega: 5V is 1023, i will use this formula:

my measurement(in volts) x 1023/5= what mega board detects at the input(the threshold numbers)

Also i am planning in the next few weeks to port this thing, on a raspberry pi with a 2.8 inch resistive touchscreen and use the touchscreen to define some "on the screen" buttons to chage trigger settings, ch1,ch2 and so on.Also guys i build a 3phase wattmeter which displays for each phase: Vrms, Irms, power factor, real power, apparent power and reactive power using 3 arduino unos.

If you would like a blog with this build let me know and i'll try to make one as explicit as possible.

[mention:4f57fc9d538949ad9eb336ddb9469bb8:e9ed411860ed4f2ba0265705b8793d05] i think you' re right about the thing with the switches..because there are switches with the same resistor value, the arduino mega won't know the difference between them and it will get mixed signals and mess up the wave form and time component(depending on witch buttons are pressed).

I will post everything here in the evening.I had my university graduation feativity and i got busy in the last few days.

Thank you Mihai Arald! It works now!

First I tried it with mp3-Input from smartphone (see picture).

What I found out is while using a 220V-to9V supply it shows whide sinus lines (without a signal in - picture 2), but when I supply the Mega with USB-supply it is different (also without signal in - picture 3).

I will test it instead a loigic probe next time.

Have a nice weekend.

Hello guys,

I'm back with the files, i'm new to this forum and i'll put this link here: https://we.tl/KmKLOOxoHo.The file contains the .ino file and the zip file of the tft library(SPFD5408) and the code change you can see in this image:

[View:/resized-image/__size/620x349/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-2139a87d-60a7-4db3-a5f2-6d03ceabf4a9/4718.contentimage_5F00_184266.png:620:349]

I didn't connected yet the switches but the programs runs fine, if you have some schematics of the wiring i would sure appreciate it, just leave me please a comment.

Hope it helps some of you out there, and Thank you vaupell for this tutorial.

Does anyone have any ideea about the resistor values in Mitsunaga's electrical schematic? Those values shown in the schematic are in Ohms or kOhms.(my guess they are in Ohms)...

recycler66 i'll post today(maybe in the evening) the full sketch, pictures, libraries, config and schematics...that is if i succed in making in work(I think i'm gonna make today my first post here on the site and post here the link)

Best regards,

Mihai Arald

Hi,

unfortunately I got no response. Is there anybody who can give me a hand?

Thanks
