Lcr T7 Firmware __exclusive__ Today

A: It approaches lab-grade accuracy for capacitance and resistance but still lags on very low inductance (under 1µH). For hobbyist use, it’s excellent.

| Feature | Stock LCR-T7 FW | Open-Source (k-firmware) | |-----------------------|--------------------------|--------------------------------| | Frequency measurement | Limited | Full up to 10 MHz | | ESR measurement | Basic | More accurate | | Calibration storage | Fixed factory cal | User EEPROM calibration | | UI customization | No | Yes (menus, fonts, colors) | | Update method | Proprietary .hex via ISP | Standard ISP (e.g., USBasp) |

You likely flashed firmware configured for the wrong LCD driver chip (e.g., ST7735 vs ILI9163). Try a different .hex file. lcr t7 firmware

Ensure you didn't accidentally wipe out the power latch management code. The LCR-T7 uses a dedicated transistor circuit to keep itself powered; the custom firmware must actively hold a pin high to keep the power on.
