Circuit to protect Saleae input from high voltages

I was browsing OSH park's shared circuits when I saw this: Logic Analyser Buffer. Since a true 12v RS232 signal will exceed the Salese's voltage limits, something like this could be useful. The diode and resistor seem straight forward enough. The…

Logic Analyzer shows voltage change in analog but not digital

While using a logic analyzer with analog voltage to test Digital Output Pin voltages on an Arduino UNO, I am seeing the expected digital output and analog output (HIGHs and LOWs for digital and 5V to approx. 0V for Analog). I'm using a Saleae logic…

Asynchronous serial inversion logic

I am using Saleae logic analyzer to reverse a console port. Saleae is able to successfully decode the signal (asynchronous serial) after performing an "invert" operation on the received signals. I am trying to figure out how this transform(invert)…

How to find and decode a particular protocol

I'm trying to understand what protocol is used on a particular device in order to decode it and send custom values. So far I was able to record the data with a logic analyzer but couldn't figure out what protocol it is and which baudrate. I'm…

JTAG 20-pin only 1 has data

I'm trying to use a Saleaa Logic 8 to find data pins on a 20-pin header from a board with a Intel X Scale (ARMv5) PXA270 processor, but I can only find what looks to be data on pin 9, I've tried (I think) all the rest of the pins, is it possible to…

Why High Speed CAN messages with a recessive level in ACK slot from OBD II port on 2019 GM Chevy Cruze

I want to collect some CAN traffic from my car. I got two devices. One is Saleae Logic8. The other is Vector VN1630A. I think the CAN protocol is straightforward that we can listen the CAN traffic by connecting our device to CANH and CANL. So I…

How do I analyze this UART signal?

I want to make the same signal like the following images using an Arduino Uno. But I can't find the baudrate of this signal. I calculated baudrate the same way as Wikipedia. But when I used the baudrate I got framing error. The duration of the start…
