I need you to analyze a small part of a protocol where 2 packets of data are sent by a microcontroller (inputs), and one response (output) is sent back to the microcontroller. I have numerous examples of the inputs and outputs in the attached spreadsheet.\r\n\r\ngreen = same common data for all examples\r\norange = different input from microcontroller\r\nyellow = different output sent back to microcontroller\r\n\r\nBased on the changes in orange sections of the spreadsheet, I need to work out the correct output to send back to the micro controller (yellow sections of spreadsheet).\r\n

Looks as an interesting reverse-engineering... however, wasn't able to find mentioned excel file, thus the details are not quite clear... for example are those input/output sent through tcp/ip or through some internal bus. please share the packet examples and I'll try to investigate and provide some updates by tomorrow

Hello, your task looks fine, I would like to help you, but there are some essential questions: 1) What is the microcontoller doing? Is it an actor, for example controlling a servo or alike, or is it a sensor, delivering some measured values? 2) In your examples table the `input` packets from microcontroller (three fix length pakets at 8+1 byte, not two) are prepended for the `output` from the host software. It seems strange, in normal live in most cases such transfers are initiated by the host software, also host pakets should be preceeding the controllers responses. Is it possible to arrange your examples in this order? Are the paket columns continuous, or may have gaps? 3) Have you already probed to send some of those software output example packets and check which response will be returned? Is it possible to do such tests in the future? A note about my timeline: If you like that we work together on this task, so I am free this week Thursday to Sunday, all the daytime from 10:00 to 20:00 gmt. Please contact me if you are interested. Best Regards, Viktor Gotwig, Cologne, Germany.
