Explain ESP-PIC UART I2C and complete Circuit -- 2
Budget: ₹1,500 – ₹12,500 INR
I already have the full schematic and the finished PCB files for a board that combines an ESP module with a PIC18F microcontroller. What I’m missing is a clear, practical explanation of how everything talks to each other, especially over UART, and how that interaction is implemented on the physical board.
Here is what I need from you:
• A step-by-step walkthrough of the signal paths that handle UART traffic between the ESP and the PIC18F, including any level-shifting, buffering, or hand-shake lines that support the link.
• A guided tour of the PCB layout that shows where those signals travel—layer changes, vias, ground references, decoupling, and any routing choices that affect integrity or noise.
• Simple notes on any supporting circuitry (power rails, oscillators, reset circuits) only as they influence that communication channel.
I will send you the schematic PDF and the PCB project files (Altium and Gerbers). You may annotate screenshots, write an explanatory report, or record a short voice-over video—whichever medium lets you convey the information most clearly.
Please be ready to start right away; I’m aiming to wrap this up ASAP. If anything in the files is unclear, flag it immediately so I can supply extra photos or measurements.
