If everything is correct, the oscilloscope will show the 4 channels [A0 ch-0A1 ch-1A2 ch-2 and A3 ch-3 ] obs: if nothing is connected you will see a noise. You will see appear a signal like the picture. You can find out the frequency that the flashlight is blinking using a LDR and a resistor see the picture. The "medir res. That function has the hability to discover by itself if the component connected is a capacitor or a resistor, and to choose the better result using 3 scales low, middle or high values.

Muy complacido. It took me only few minutes to up and run. Very pleased. Question 2 months ago. I'm having some issues with the program. The demo and all the measurements of the program works fine, but, for some reason, when I click "off" to turn the application on, it chashes. Furthermore, when the apllication crashes and closes, a.

Minidumps are not enabled by default on client versions of Windows Anyone can help me with this?? Hi there, I try to get the data on my serial port, but when I do so only hieroglyphs appear. I matched the baud rate of the serial monitor with the one in Serial-begin.

Is it possible to write the high frequency ADC data in the serial port with a high baud rate? I want to read out the serial port with a python code.

Thank you for your help. I'm looking forward to reading your answer. Reply 2 months ago. In the arduion program. You can try too, change 8 bits or 7 bits in your serial port. Question 9 months ago. Hi, i was doing a experiment where i use a function generator to display a sin wave. Answer 2 months ago. It means it can only read the positive portion of your wave as it cannot read negative voltage signals. Question 3 months ago. Most arduino boards are limited to 5V for inputs, some are 3.

However, you can always use a voltage divider to measure higher voltages. I didn't do this instructable yet, but it looks like you can set in the PC software the voltage divider you are using so it will show the proper voltage reading.

Hi, I wanted to measure v volts from an external source to see its waveform and needed help to understand the wiring to take such measurement. Do I connect positive of external source to analog pins A and negative of external to gnd of Arduino? Can you kindly tell me if I need to change anything in the code to take such external measurements? Any other precautions to protect the uno? Additionally, when you say 4 channel, does it mean I can use analog pins A0, A1, A2 and A3 to connect to 4 different positive inputs from 4 different circuits?Welcome, Guest.

My target was to keep everything as simple as possible, avoiding any additional hardware, so no external RTC, no external DACs. The following users thanked this post: oPossumedavid.

Maybe a dumb question, but how do you get separate, disconnected line and curve segments with only X and Y?

Don't you need a blanking signal too, to hide the trace as it moves between graphic elements?

Or can you just "move it really fast" when you don't want it to show up? And would that work on a real CRT? This will generate several unwanted points that will appear on the drawing. See the attached picture where you can see all the points generated by the code displayed using an Excel chart.

JPG The following users thanked this post: Ysjoelfir. Thanks for posting this great project. I built mine on a small perfboard and used BNC jacks. I ran into two small issues with the NTP library that I'll mention to perhaps save others time. Looking around the code it appears it was perhaps based on some previous ESP code.

Esp32 oscilloscope 40Msps!

We can get up to 18Msps with 6-bit resolution and 10Msps at bit, which is pretty good taking into account the simplicity and price of the device. The only problem is the proper design of the analog front end which is not that simple when you want to have both low cost and proper quality at higher frequencies at the same time. But it looks like I figured out all the needed changes and ready to prepare the next revision of the PCB to test my ideas.

This is the simplest way to generate an analog clock on the oscilloscope display. The oscilloscope should be two-channel, one channel for the "x" axis and the other for "y".

By default this sketch will start from a fix time everityme you reset the board. To change it, modify the variables h, m, s below.

Check in the serial monitor if it can reach the NTP server. As you can see on the circuit, pin 25 of ESP32 is connected to "x" channel 1 of oscilloscope, and pin 26 to "y" channel 2. Then we select a X-Y mode of operation of the oscilloscope. Connecting is done with shielded cables. On the video you can see flickering in the image, which is a consequence of the outdated oscilloscope.
