UART, I2C and SPI for sure! Much more useful than CAN in my opinion. Glad to see the Beta has I2C in it now. One more suggestion on the UART, is if you could make it RS485 compatible, you would have a real winner.

I am holding back on the deep memory 4 channel version until UART is supported. Once it is, you have another sale on your hands.

Thanks for an already great product. My Tek scopes are collecting more and more dust around here.

I'd like to use PicoScopes in an ATE setup but without UART & SPI serial decoding, I am looking at much more expensive products and/or s/w options.

The only alternative I've found for the PicoScope so far is: WaveBPS from here:

Hi There,

Thankyou for all the postive comments that have been generated on this subject just to inform you a new release of software is available

A new release of software is also available from Pico R6.4.28

These newest features in PS6 are as follows:-

Merged channel options button and channel label
Automatic device reconnection
Alarms
Buffer overview navigate on mask fails
I²C decoding
Added bitstream to AWG creator

Have fun

Kindest regards,

i agree with all of you!
For individual use it would be perfect if picotech offers a plugin system, like someone else already suggested. Then everybody can desing individual needed decoders. In my case for example DMX. I guess because of less users interested in DMX, picotech won't implement DMX decoding next time...
Because of this it would be nice if picotech would think about such a solution that customers can help themselves...

Regards

Hi Christian,

Thank you for your suggestion, I have forwarded your idea to the relevant department. Obviously no promises can be made, however every enquiry will be looked into.

Kind regards.

No, that was a terrible suggestion. :(

I think. *Most* customers will probably just need UART or SPI coding. A few months ago, you made a questionnaire about this with all your customers, so you should know by the numbers, what the customers want.

Picotech, make it easy for yourself, and for the customers, just add UART/SPI like you added CAN. Several of the previous comments on this thread also suggest this.

Here comes one more vote for additional serial protocols:
PLEASE picoscope add UART and SPI !!!!
I am about to purchase picoscopes for my company, I am still hesitating due to lack of functionality regarding missing protocols, but I hope and I am confident that you guys manage to add this in the near future!

Hey Picotech,

Do you have any news on what is going on wrt. UART and SPI decoding?

Best,

As a matter of fact this is much sooner than you think, I would keep an eye out for our labs webpage over the coming days:

Thanks for the UART and SPI decoding! They both works and they are a great asset during product development. :) I really think they should pay back to you in terms of new scopes sold.

There are a few points for improvement.

1. The UART gets confused if the chars are comming without time spacing. This is a problem.

2. The excel export (only tried SPI) a data sheet. This data sheet has too much "looking pretty" formatting. The time should not be exported with "1.2us" or "3.5ns". The time unit should be in a separate cell.


I already have a new project that will need both UART and SPI. Great gear.

The same problem of UART getting confused with chars without spacing has also been reported by maxsca and elman on another thread. maxsca has included psdata file.

I am working on another aspect of my project at the moment, so I can not make a psdata file with UART problems. :|

No problem, thanks for pointing out the problem either way we are working on a fix.

Hi,
If you haven't already got a sample, I've got a screen shot & psdata for the UART back to back timing issue. ('1', '2', '3' sent)
It looks like when you specify 8n1 the UART decoder is actaully waiting for all 10 bits (start, 8 data, stop) and so missing the falling edge of the next start bit. All it needs to do is wait for 9.5 bits like a real UART would.

You are probably already on to this though!

Best Regards,
