A cheap USBASP programmer or an Arduino configured as an ISP is perfect. lcr t7 firmware
An USBASP programmer is required to connect your computer to the tester. Adds frequency generation
In AVRDUDESS, set the Flash section to and select your new .hex file. rotary encoder support
The firmware does not match your display controller chip (e.g., trying to use an ST7735 script on an ILI9163 screen), or the display reset pin layout configuration in the source code is wrong.
Configurable auto-shutdown settings to prevent battery drain.
