Ensure the internal battery is charged before starting to prevent a mid-flash shutdown. 💡 Final Thoughts

Refined algorithms for ESR and capacitance.

You will need a .hex file (the flash memory) and a .eep file (the EEPROM memory) specifically compiled for the T7's display controller (often ST7735) and microcontroller. Step-by-Step Guide to Updating LCR-T7 Firmware

| Problem | Likely Cause | Solution | |---------|--------------|----------| | avrdude: “target doesn’t answer” | Wrong wiring or no power to target | Check VCC and GND; power LCR T7 via battery. | | White screen after flash | Fuse bits incorrect | Reflash with the exact fuse commands above. | | Component detection still inaccurate | Missing self-test | Run the self-test by shorting all three probes. | | USBasp not recognized | Missing driver | Install Zadig (Windows) or libusb (Linux). |
