16x32 S4 P10 Mapping issues


I’m trying to map a P10(3535)16x32-4S-M2.1 display based on a MBI5124 LED Drivers with the 74HC245 on the interfaces and have found the message Mapping Assistance 32x16 P10 which is the closest advise I could get for selecting the correct paneltype of SM_PANELTYPE_HUB75_16ROW_32COL_MOD4SCAN_V4.

When using this or the paneltype SM_PANELTYPE_HUB75_8ROW_MOD4SCAN_ALT_ADDX it does not show 1 pixel but 31 pixels, sorta like it’s inverted.

When moving coordinates the line moves up the panel.

Any pointers as too where I should look to understand why the entire row is shown except 1 pixel? Is there a row inversion option (Tried the SM_HUB75_OPTIONS_ESP32_INVERT_CLK but this does not work suspect I need to invert the R1 line instead).
