can any one explaine how the atu-100 gets read fine by the pickit 3 programer but wont display anything on the oled ?.

display type ...?

Try flipping over the SCL & SDA cable connections at one end either ATU PCB or OLED.

the display is the "0.96 i think it is its the standard oled that came with the kit,alo i have tried an lcd also swapping clock+ data lines,same result dark display,it has 5v+ gnd also,hence why i posted the fw dump.

also all oled displays work ok on another unit.

Hi Paul,
Looking at the HEX file you posted the display settings you have are for the PCF8574AT, 1602 LCD display not the OLED.
Addr 00 = 4E
Addr 01 = 01

For the OLED display, the standard settings are as follows.
Addr 00 = 78
Addr 01 = 05
