Click next to the fuse inputs. Caution: Incorrect fuse settings can permanently brick the microcontroller ("lock you out"), requiring an external high-voltage programmer to fix. 5. Flash the Updated Firmware
This usually means the firmware you flashed does not have the correct display driver (ST7735) compiled into it, or the pin definitions for the display reset/data lines are incorrect. Reflash a version compiled specifically for the LCR-T7 layout. lcr t7 firmware updated
Most enthusiasts choose between two primary open-source versions: Click next to the fuse inputs
Measure a 10µF 25V electrolytic capacitor. Old firmware often reads 7-8µF with high ESR >5Ω. The new firmware should read 9.8–10.2µF with ESR <2Ω (for a healthy cap). Flash the Updated Firmware This usually means the
While development is community-driven, stable versions like 1.13k or 1.46m and above are commonly sought for their improved accuracy and dark mode UI options. Update Process (General Steps)
Download the latest firmware files (.hex for flash and .eep for EEPROM) from community repositories like GitHub (Ho-Ro) .
