New SF OLED Carrier board and Display

I just received my new SF OLED Carrier board and display. I unfortunately burnt both of my first ones after a botched effort to removed the solder jumpers.

I had the first display working just fine. Initialization, etc, worked every time.

However, I am unable to get the new board and display to light a pixel.

Has anyone recieved a recent (within the last several days to a week) carrier board and display and got them working.

I suspect that some parameter on either the board or display has changed slightly - but, have not been able to determine what it may be. It will probably be so simply I will kick myself - but, right now it would be worth it {:>)

Thanks

We haven’t changed anything on the boards [Unless your first boards were a long, long time ago].

Hi David,

Thanks for the response. I found out the problem. I also just got a new development board. I had been using my old development board/chip to drive the SF carrier board/display. With the new development board, For some reason, one of the board chip’s display command pins (R/W) was not maintaining the high state I initialize it in. So the Display controller was not getting a “Write” command.

Periodically re-initalizing the pin to the logic High state fixed the problem. Only caught it because I noticed the led attached to the “R/W” chip pin was not lit and blinking as were the other pin LEDs.

So board and display are working fine.
