Search a Sequence of Bytes


R
Rei Vilo

I soûle lime to perform a search of a sequence with multiple characters or bytes.

Example: search for 0x47 0x09 sequence on an I²C frame.

"Hi,
I took a trace from SPI lines and I want to find a specific sequence in the trace. I saw a way to find one byte but didn’t find an option to find few bytes togheter:"

Add the ability to search for multiple byte sequences in the SPI (and other) analyzers. It is quite common to need to search or filter for a SPI command sequence, like 0x9F 0x2B 0x3C (not just 0x9F). Even better would be search a combination of commands (MOSI) and responses (MISO).

Example: read [0x14], 0xA1+ack 0x00+ack 0xA2+ack 0x00+nak
if I want search "0xA1 0x00" string , can do it ?

Good question. Unfortunately, sequential search (i.e. "0xA1 0x00") are not possible right now.

Right now, only individual entries can be searched (i.e. "0xA1" or "0x00", but not together or in sequence). I went ahead and merged this with the idea post above so that we can track your need for this as well.

Searching for a single character doesnt help here very much."

"if I want to find a sequence of bytes: 0x13 0x07 0x00, how would I enter that in the search bar"

I would love to be able to search by sequence of bytes, or just text in the decoded data. I am often analyzing GSM modem AT protocol, which is mostly text over UART, and I would like to be able to find one specific command, like '+QIRD=0,1,5rn'. Currently the data window allows searching for single byte only in UART communications, which does not help at all.

I would add that the same search routine could be also be used for more advanced triggering. Or should I add that as a separate suggested feature?

We're working on trigger on protocol now!

And search in the Terminal frame.

Could you suggest this as a new idea?
