0 SithRuoss 2 Posted January 3, 2016 Found a mistake.The Define statement would #define prtDataCmd IOPORT_F and not #define prtDataCmd IOPORT_E 1 JColvin reacted to this Share this post Link to post Share on other sites
0 JColvin 342 Posted January 5, 2016 Hi SithRouss,It should be IOPORT_E rather than IOPORT_F as you found. I'm guessing that whoever created the header file misread the schematic for that particular pin since it (at first glance) does look like it should be on Port F rather than Port E (at least on the schematic).There are two things that I can think of that you should try, having worked with the PmodOLED quite a bit. The first would be to make sure that you are applying 3.3V of power to the Pmod rather than 5V. The second would be to actually tie pin 1 of the PmodOLED to Ground (0V) to ensure that the module on the PmodOLED stays enabled.Let me know if you have any more questions.Thanks,JColvin Share this post Link to post Share on other sites
Hello Community,
tried the library PMODOLED adapt, so that I can use from my Cerebot Pro MX7 at port JE.
Unfortunately, however, comes only noise from the display.
Has anyone any idea what I have done wrong?
thank all inputs
