    I have already done!
    (crossed message)

    5V (near the pin 1) and 1.5V on the other side

    Well with power on you should be able to measure voltage on both sides of the diode relative to ground.

    Measure both and post the results

    I have made the test with power supply and i have 5V on the diode side near the pin 1 and 1.5v on the other side.
    Is it OK?
    If no, can i replace it? What is the reference of the component?

    Thank in advance.

    About the diode next to the pin 1, what kind of tests do i do?

    Do i apply power supply to make the test?
    If yes, do i check voltage value on the 2 pins?

    impedance (power supply off)?

    Can we have the electric scheme of the card?
    what is the kind of the diode?

    Sorry, if there is stupid question but i'm not doing electronic tests usually.
    I could do it but i need a good driver!

    Thank in advance

    Yes, the run jumper is between pins 6 and 8, it should be removed for 'normal' operation.

    What about the diode next to pin1 of the connector? is that still operational?

    By the "RUN jumper", do you mean "jumper between pins 6 and 8"?
    If yes, i have removed it and the pin 6 is not connected (no pull up no pull down).

    note 1 : I'm succes to work during 2 days in this configuration.

    note 2 : I have no SD card;

    note 3 : If i put the "RUN jumper", nothing happen too.

    You haven't got the RUN jumper installed have you?

    This could cause what you are seeing

    started a topic µOLED-160-G1 (SGC) doesn't respond

    µOLED-160-G1 (SGC) doesn't respond

    HI,
    I'm working on OLED-160-G1 (SGC) since 3 days via my PC. I started to write some menus for our application and all were OK.
    I have BLANK screen at the boot and after the home menu of the manufacturer appears.
    I launch my Autoboot command and the endcheck comes and i can drawn and write on screen whith
    no problem since 2 days.

    This afternoon suddenly, i power up my module and nothing happen. (same process as my previous tests)
    There is no answer to my AutoBaud command and no launch of the manufacturer home menu.

    what happpen?


    Please, advise me.
Working...
