Decoding oscope?

(1/4) > >>

Tech_Monkey:
I dont really know what Im talking about here so hope you guys can help. My other half is in school for EE and was working on a project with a MSP 430 board. simple program that outputs the hex of a letter / word in I2c (?)   anyone know of a cheap oscope that can decode the signal and display it?

ataradov:
Get a cheap logic analyzer. It is far better for decoding protocols and WAY cheaper than the cheapest scope with decoders. Like this https://www.amazon.com/HiLetgo-Analyzer-Ferrite-Channel-Arduino/dp/B077LSG5P2 or one of million other variations. They all are basically the same.

Also, I2C requires two devices on the bus to work, you can't just output stuff like you do with UART, for example.

Tech_Monkey:
there is some sort of daughter board involved so Im sure she already knew that and had it covered. just looking to upgrade her home lab a little for her.

ataradov:
Cheap scopes don't have good decoders that are not frustrating to use. If you want to get a scope, then get it for the scope itself.

And it is always better to ask what SO needs. Event the cheapest decent scope (and not a toy) will cost $300-500. It is a lot of money to spend blindly without evaluating actual needs.

Define cheap.
