    Heiner Please can you tell me exactly what to do?

    I have tried with the diode between


    The PIN DATA of the display and the PIN SDA of the Minitiouner Pro2 Connector JP3


    In any way I put the diode the issue does not come out but the display does not work

    Thanks

    Heiner,

    to be clear please can you tell me the exact pins name as you put both SCK then correct to SCL but

    if you have a look on the previous message, the display PINs and the Minitiouner ones has some PINs named different between

    them.

    Danke

    Hello Heiner,

    today i have tried how i said last day to box the Minitiouner.

    After have boxed it i got again the Problem, unboxed again and tried step by step

    which could be the problem. First i have fixed just the board and tried it. Powered up and it worked perfectly,

    Then i have connected all the LEDs and retried again. On this step again all OK finally i have plugged the display and retried.

    Guess what? the problem popped out again. So re opened the box, unplugged the display, re powered on again and it worked again

    perfectly. So i think the problem has to be with the Display but i cannot understand what could it be as the Display comes already assembled.I have connected in this way:


    The VCC of the display to the VCC of the Minitiouner Pro2 Connector JP3
    The DATA of the display to the SDA of the Minitiouner Pro2 Connector JP3
    The TC/CLK of the display to the SCL of the Minitiouner Pro2 Connector JP3
    The GND of the display to the GND of the Minitiouner Pro2 Connector JP3


    The only thing i can think maybe something with the bridge soldier

    done from the middle Pad and the Pad named I2C of the display.

    Do you have any idea??

    Thanks a lot

    P.S. to complete the test i have tried to connect the display one pin at time making the test on each

    connected pin and have noticed that when i connect:


    The TC/CLK of the display to the SCL of the Minitiouner Pro2 Connector JP3


    I get the problem.

    IK8OZV Enzo please post what you finally have found as the root cause... pefect.. glad to see that it is working now..

    Heiner, i did nothing. Do you remember that i said to have the problem since i have boxed it?

    Ok Tonight i thought to unbox the board so tomorrow i could change the NIM. Well after have unboxed it i put it on the table just the board, no LEDs no switches.Powered up and puff as soon i powered it, i got the Beacon signal.Until now i have tested it from 1500KS (Beacon ) down to 125KS. I am now testing with a 66KS signal. i got all the smeter fully clockwise and all the LEDs on the bottom left green.

    On the bottom right i got all the LEDs green except the last one that switches from red to green and from green to red. I do not know if it is an my problem or it is his problem.Now i have the LNA gain fix to 10.5dB.

    Can you tell me what can it be?

    Thanks once more for your helps
