That's awesome, a handheld scope with a small display that fits in your hand, with additional useful features a very nice project, good job and very helpful content.
madness, not even famous electronic channels dare to attempt this, making both an oscilloscope and the video manual, now I'm curious how far can you develop this oscilloscope, I'll wait for your next upgrade
Very cool friend, your work would be able to update to the 128X32 LCD display So it would be easier for us to copy your project to make an oscilloscope pen
Hello Lau, The high frequency spike issue can be solved by adding a capacitor 10 nF across port pin P06 and Ground which filters off the High frequency spike. Please try.
that's a bloody class little project!! and if you cant solve the jumping issue change chip's. it will be worth it!! : ) P.S. i never knew a DSO could be made with such little components....
Very nice! I'm making an stm32f103 version. I'll post a video.it's really fun. I don't draw lines that go outside the screen. This way the user isn't confused by a voltage level that really doesn't exist.
I'll make a video, and we can help each other. I got 2 channel ADC with DMA transfers. I used 200k on my input probe going to a resistor ladder so I can get +-140 volt. But I get a lot of noise. Not sure why. Any ideas?

Great work and efforts
Impressive piece of embedded engineering
I like it, keep up the good idea's Creative Lau.
Thank you for your support.
Is there any possibility to make voltage range upto 400v?

please port the code to raspberry pi pico. this will be more powerful.
这个项目非常棒。持续关注中，如果可以的话 使用esp32 可以把显示与控制部分放到手机上，那样可以显示更多的信息

Amazing. Thank you for sharing!

Hey :D What happen with your project using STM32 MCU. We have waiting 3 moths :(
Thanks you for sharing. 😄😄
Good job lau
can you give an example of making a simple code into a hex file and then program it to the micro controller stc
Thank's
awesome
great project. hope you transfer the project to ESP32
esp8266/ESP32 can also be a good move. (+bonus bluetooth connection like PokitMeter products)
Thanks for your advice. After complete the transfer work of STM32. I may consider ESP32.
@@TonyVieira . that's a nice one but to hassle around with the phone as well???? no thanks. the concept of what Lau made is perfect for basic testing.
Esp's adc is not very good.
WOULD LIKE TO MAKE A NEW VERSION WITH 2 CHANNELS WITH A LITTLE LARGE SCREEN FOR SAUCE VISION
你是老劉嗎?😅
我就知道你有youtube，从西瓜视频看过来的，以为是搬运工
amigo pode ser feito com (STM32G070 RBT6)
friend can be done with (STM32G070 RBT6)
