Read/Write HEX File from Arduino Pro Mini (Delhi NCR Preferred) Project Description I am looking for an embedded systems developer with experience in Arduino and AVR microcontrollers to help with the following tasks: Read HEX file from an existing Arduino Pro Mini board (ATmega328P). Write (upload) HEX file back to the Arduino Pro Mini using a programmer (USBasp / FTDI / Arduino ISP). Provide a step-by-step process/documentation so I can replicate the read/write process in the future. Help troubleshoot any programmer/driver issues (e.g., AVRDude errors, sync issues, missing programmer errors). Technical Requirements Strong knowledge of Arduino Pro Mini (ATmega328P) bootloader and memory mapping. Experience with AVRDude, Arduino IDE, and command-line tools for reading/writing HEX files. Familiarity with USBasp / FTDI / Arduino ISP programmers. Ability to verify successful backup and restore of firmware. Preferred Location Developer/freelancer should be based in Delhi NCR (India) for smooth communication and, if required, in-person hardware debugging. Deliverables Successfully extract the HEX file from Arduino Pro Mini. Re-flash/write the HEX file back to another Arduino Pro Mini. Provide clear documentation or video walkthrough of the process. Support in resolving any programmer or driver errors.
