STC8G1K color oscilloscope

You can make something by fishing, see the video at  https://www.bilibili.com/video/BV1N44y1E72R

The code has been open sourced, see the end of the article

Oscilloscope parameters:

AD input voltage 0-3.3V/5V (depends on the screen)

8bits@200Khz

1-2-5 time base step from 5us to 500us

Vertical magnification 1-2-5 times

Three triggering methods, 10 trigger levels from 0-90%

Waveform measurement function

The core board is based on my project  https://oshwhub.com/Eltecz/stc8h1k

----------

The schematic diagram is for reference, LAYOUT is not drawn, and the TSSOP20 microcontroller will be used to make the actual object. The new version of the oscilloscope has been produced, see [Station B] / [LCEDA]

Note, please adjust the frequency to 32Mhz when downloading

Note: If you use a microcontroller with 8kb Flash space, please change the compilation level to -level 9, and the compilation option needs to be changed to favor size

Please go to stcmcudata.com to query the file creation of STC microcontroller, which will not be introduced in this article.

----------

The programming ideas and source code have been updated to station b and other platforms .
