I have an extensive experience with microcontrollers of several families, such as LPC1768, ARM Cortex M0, M3 and M4, TM4C and of course, ESP32. I have utilized microcontrollers for several purposes, such as motion control, image acquisition, remote data sensing and human-machine interfaces. For most of these applications I have designed and built the full stack of physical information flow: from data acquisition and conditioning through processing up to presentation/visualization on a Graphical User Interface. Granted, I have also built for the inverse flow: specifying desired outcomes on a GUI and effecting them in the physical world by means of an electronic device. For these constructions I make use of a wide range of technologies, such as C++, Python, ZeroMQ, PostgreSQL, MongoDB and Django.
For this particular project, I wouuld need from you some details, such as your devised byte frames for data exchange among the ESP32 devices and your chosen LCD display for presentation of the data. Once we have synchronized on these issues, I can get to work and come back to you with a complete implementation. Of couse, the implementation would have been physically validated on a prototype I build with the incumbent device references.
