Using a tool like MPLAB IPE (Microchip’s programmer) or PICkit 2/3, read the existing firmware from the PIC microcontroller:
Click the “Test Interface” button. This sends a challenge-response query to the hardware’s firmware. opcom 167 firmware verified
Yes, but it is risky. You need an external programmer (like a USBASP or TL866) and the original 1.67 HEX file (which is copyrighted and legally difficult to obtain). The process involves: Using a tool like MPLAB IPE (Microchip’s programmer)
Unless you are an embedded systems engineer, this is not recommended. One wrong fuse bit and your OP-COM becomes a paperweight. Unless you are an embedded systems engineer, this
Verification is not automatic. You must manually check the handshake between your hardware and the software. Follow this 6-step protocol.
