Get the Boldport Cuttle to write its name on a Digital Oscilloscope with an MCP42010 digital potentiometer.
I just built The Cuttle so time for a quick test.
I thought I'd borrow an idea from the XYplotter project and get The Cuttle to write its name on an oscilloscope.
The Python script make_data.py is used to interpolate plotting points over the fundamental text structure. It generates the data.h used by the ScopeTag.ino sketch:
python make_data.py > data.h
When running on The Cuttle, it produces the image below. I'm using a Hantek MSO5074FG oscilloscope, and the image was captured with the following settings:
- XY plot mode
- 0.2s persistence
- display as vectors
- average over 4 samples
- CH1/X offset by -4V
- CH2/Y offset by 40mV
- 570mV per grid
The time-domain plot for the generated output is like this:
- LEAP#265 XYplotter - the scope XY plotting project
- LEAP#266 The Cuttle - building the cuttle
- MCP42010 datasheet - parts.io
