Found out oscilloscopes make a much better screen for embedded devices than SPI/I2C displays, only 2 wires needed and no complicated protocols 8

Driving the oscilloscope using the inbuilt headphone amp output of the AMB21(RTL8722DM) dev board, probably could have achieved better resolution if I could access the DAC outputs directly.
Is that 1054z? in that case if you havent already done this i recommend you [this video](https://youtu.be/AnxOGl27GjE), and [this is the site](http://gotroot.ca/rigol/riglol/) shown.
100% worked for me now i practically have a 1104z
Neat, I used to have a program that’d play asteroids on it over the headphone jack
I always wanted an scope with an “intense” input so i can use an video seperstor ic ore something
Another great display project is programming a micro to run an LCD on UART protocol. Then you have a device no bigger than the LCD that you can dump characters onto with a single Tx pin.
It’s really easy to express detailed information via plaintext. It only takes about a microsecond per character to transfer at the lowest 9600 baud, so it barely affects most code you’d be writing👌
EDIT: Bonus points if your UART protocol has opcode packets in the frame to reinterpret bytes for different display formats.
For example:
* 0x00 means display the next byte as a character
* 0x01 means display the next byte as a signed integer
* 0x02 means display the next 4 bytes as a floating point number
* and so on…
Where did you buy those adapters for the oscilloscope probes?
So we’ve gone from vector graphics to raster, and then back to vector again…
Amazing.
Idea for a project: replicate Atari’s Quadrascan and run Asteroids on it.
