...current than pull-up resistors for incremental encoders connection. If required, a signal amplification needs to be implemented. Standard signal voltage is 5V DC. Main Purpose: 1. Noise Reduction: It should provide clear communication by suppressing ambient noise in the signal. There is a 23V AC 16KHz ground noise against a vehicle chassis where the board is intended to be used. So, ground needs to be isolated. 2. Signal Distribution: The designed board will serve as a hub for signal distribution in my project. The original signal shall be provided as an output of the board with the original ground while the splitted signal shall be used for internal processing on the micro-controller with isolated signals and ground. Two AB incremental encoders shall be connected to the ...

...source code. The review should encompass the following: - Identification of any potential issues which could result in undesired behaviour - Identify any obvious errors in logical design or use of pointers, arrays etc Lint has already been run on the software - I do not want to see the output of lint! This code has been tested on hardware and performs ok. It controls motors, reads switches, encoders and ADC's, and drives eeprom and digipots. I need a final check to capture any errors or issues that may not be known. I do NOT want any style or general commenting recommendations - the review is ONLY TO IDENTIFY serious issues. I do not want speedup suggestions. This is close to production so any changes *need to be necessary* to improve the quality of the code. Skills an...

We don't need it to transcode or anything, just pass through the stream to another RTMP that we have provided. The goal is just to be using an RTMP that uses our URL, and then we can send it on to any other RTMP server we need. I'd like it to be done using Wowza so we can just pay based on usage (passthrough only) but not 100% set on that if there is something easier / cost-friendly.
