Before you proceed, you need to understand what’s inside your tester. The LCR‑T7 is not a single, uniform device. Over the years, different clones and versions have been produced with different microcontrollers (MCUs):
If the update fails or you don't like the new version, you will want the original to revert to. Connect the USBASP to the LCR-T7 ICSP pins. lcr t7 firmware updated
Note: Make sure your USBasp jumper is set to 5V power supply delivery, as the LCR-T7 logic circuit relies on 5V via its onboard step-up or voltage regulation system during programming. Step 5: The Flashing Process (Using AVRDUDESS) Plug the USBasp programmer into your computer's USB port. Open . Select your programmer type (e.g., USBasp ). Before you proceed, you need to understand what’s
