Question 1

I'm resurrecting an old project trying to decode a serial protocol from my underfloor heating system (OJ Electronics). Not been able to rule out OpenTherm. Async Serial decoding of underfloor heating ...

Question 2

I am an electronics engineering student currently working on a BLDC motor driver project with my team. My role is in software development. We are using the STM32F100RB microcontroller and coding it in ...

Question 3

I'm trying to decode a serial protocol from my underfloor heating system (OJ Electronics) Example of bus communication sent every 11s is quite small and looks like: This will need to contain info ...

Question 4

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 ...

Question 5

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 ...

Question 6

Many attempts to write to an i2c slave to make rgb leds light up have failed. The hardware in question is found at: https://learn.adafruit.com/adafruit-neotrellis There is an arduino library and a ...

Question 7

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 ...

Question 8

I'm using this famous logic analyzer and I would like to know if I can change the waveform into binary, like I've done in this pic (white numbers).

Question 9

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 ...

Question 10

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 ...

Question 11

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 ...

Question 12

I'm trying to use USART in my program on STM32F205VC, but instead of sending my data I get some weird chars in PuTTY. I've used a Saleae Logical Analyzer and the result looks like this: This is my ...

Question 13

This is a long post as I want to take you through all the work I've done. The TL;DR version is I've got an unknown controller for a mechanical heat pump and I'm trying to reverse engineer the signal ...

Question 14

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 ...

Question 15

To continue of this question... I figured out the main problem and now I have an odd problem. at first, let me to put the codes. "Main.c": ...
