Создание анализатора верхнего уровня для логического анализатора Saleae
Компания Saleae производит логические анализаторы и предоставляет программу Saleae Logic 2 для отображения, анализа и логгирования данных. Logic 2 поддерживает разнообразные интерфейсы и протоколы и их декодирование. Для расширения функций анализатора в Logic 2 появилась возможность создания своих обработчиков и декодеров протоколов. В представляемом материале рассматривается создание своего декодера - анализатора верхнего уровня (HLA). Зачем? Например, есть последовательность передаваемых по SPI байт. Стандартно, при правильной настройке, вы увидите значения этих байт. Но, может возникнуть вопрос интерпретации полученных данных. Декодер может помочь в выводе данных в удобном виде и/или упростить анализ (reverse engineering) неизвестного протокола.

Does anybody have a reverse engineered spec of the current Saleae Logic2 .sal format?
I understand their point of not releasing spec, I just disagree and want to parse my own files anyway. And yeah I know that export is possible it just adds too much friction.

A few days ago, I fried my #saleae pro logic 8. I've bought the device over 8 years ago. This was quite a downer, as the device is quite expensive and I've used it just for non-commercial stuff.
I've chatted with support about how I can buy a replacement. I did not expect much, as this was clearly my fault and the device was way beyond warranty and I even could not find the receipt.
They immediately offered to send out a replacement part without any charge! This is just awesome.

Just spent an hour chasing a problem with a DAC output, it was a bit wobbly and didn't reach the full 3.3V.
Just by chance I swapped the inputs round on my Saleae Logic Pro and the fault went away...
Swapped back and it returned, so it looks like I have a bad channel :(

Success!
At bottom: what Saleae Logic shows after trimming data from a capture.
At top: the "trimming" is an illusion, Saleae actually stores more signal than you asked for, and it can be revealed through a simple file rewriter. Hope it wasn't, like, secret.
This behavior is controlled by ~3 fields in the analog capture file, and looks deliberate. It seems difficult to achieve by accident.

Got a bricked #ticwatch spitting out some data. Likely its last words just spoken though the #saleae 🪦 Proper lunch break ✔️ #reverseengineering

Aaaannnd we caved and bought a set of #sensepeek #pcbite probes, the 6019 kit. It'll go great with our #saleae and #analogdiscovery3 <3
And thanks to that we're reaching the point of wanting to buy fancy *boxes* for the fancy equipment - a nice metal carry-case and some Cut-And-Peel shadow foam, make a nice multi-layer storage compartment for the small clip-probes and bigger oscilloscope leads, maybe the AD3 adapter boards a layer below...

First things first when attached to my digital scope #saleae there are no obvious communication on the labelled pins.
Only a single pin changes state on boot, going high for 1.7s
Next I started to pull the pins high and low to see if any thing changes and it turns out that PB2 allows you to change from Celsius to Fahrenheit - this explains the button that is inside the case, you must press it and it pulls it high -
Обзор Чипа Внешней I2C Памяти AT24Cхх
AT24C02M5/TR это EEPROM на 256 байт с доступом по двухпроводному проводному синхронному последовательному интерфейсу I2C. В разработке электронных плат часто надо подписывать электронные платы каким-то серийным номером. Это нужно для идентификации платы при серийном производстве. Внешние чипы памяти особенно важны так как прошивку могут полностью стереть. В связи с этим хранить серийный номер на микроконтроллере внутри on-chip NOR-Flash самого микроконтроллера ненадежно.

Hello here, I am selling my Saleae Logic 8. A nice little 8 channels (digital/analog) 100MS/s USB logic analyser. Perfect condition, all accessories.
Let me know if you are interested, or share with someone who might be 👍

As a recovering perfectionist, I know that it’s pronounced “say-lee-ay”, but I’ll never find it not funny to pronounce it sah-leh-ah-ehhh instead.

My favorite - and most expensive - coaster: 16 channel #Saleae
Its internals were fried in an unfortunate accident and so removed.
Just because we’re broken doesn’t mean we’re useless
