Hi Forum,
I have a custom display with 7-segment displays based on an ESP-01 and 4 MAX7219. Up until now I have used it with custom Arduino code but I would like to use it with ESPHome. My problem is that apparently the commercially available displays are wired high to low, so digit 7 is the first and digit 0 the last. My custom display is wired low to high though so any values sent to the display are in reverse. I send 01234567 and get 76543210 on the display.
Is there an easy way to solve this in ESPHome? The reverse_enable option only reverses the order of the MAX7219 ICs in the daisychain, not the digits themself.
I would love to use my display with this to show values from HomeAssistant but right now it is obviously quite useless.
