If you had a sensor who’s analog signal you wanted to modify in real-time, for example you did an engine swap and the new engine’s sensors weren’t compatible with the original ECU. Say they used a different voltage range or hertz rate. Would an fpga be overkill for this application? What would be the correct topic to google?
- AnarchismIsCool 3y agoIf it's a digital sensor and you're modifying a digital bus then yes*. If it's an analog (voltage based) sensor then no, but if you know the input and output ranges you can probably build a gain stage out of much cheaper and simper components. *"Real time" is complex though, the best you can probably do is slightly longer than the time it takes to receive plus transmit the packet, best case slightly longer than the longer of the two processes.
- speakspokespok 3y agoThank you very much. Do you have general suggestions of where to look? Do I "just" need to learn analog circuit design?
- AnarchismIsCool 3y agoCan you give me a better idea of what the two signals are? I can probably point you in the right direction.
