    logo on digital meter

    Can anyone help me?

    I want to have my own logo on all my digital current-meters and voltmeters for my own pride. I know they are using one-time ROM (OTR) but I can change it and I can write a computer program and burn into the memory.

    I have this(OLED 7-in-1 Electrical Parameter Meter Multifunctional Power Meter Voltage Current Time Power Energy Capacity Temperature Tester), how can I modify the firmware?

    Maybe from the ground-up will be easier. https://youtu.be/lrugreN2K4w
