  1. Hi, I use uC 32 and Basic I/O shield in my microcontroller programming class. I am using utility functions provided in class to display strings on the OLED, but it is not working. I am not sure whether it is me that made mistake or the OLED is broken. All other things (SW, BTN, ADC, and LED's) are working fine with the utility functions provided to control them. I tried to get help from TA, but with remote class and all, it is rather difficult. Can someone share a easy way to check if the OLED is functional? I am using Pickit3 to program uC32. Let me know if you need any more infor
  2. Hi, I want to connect the pmod oled display to my raspberry pi, but I'm not really getting the hang of how I should wire it. If someone can explain where to plug in each pin and how to code it that would be great. Thank you.
  3. Hi, I'm a newbie trying to learn about the Genesys 2 board and would like to program the onboard OLED as an exercise. I'm following this tutorial. There is a prominent warning that says "Important! Make sure to turn off the OLED display before shutting down or reprogramming your board." Why? What will happen if I don't turn off the OLED display and simply turn off the power switch? Will it get damaged? This makes me very nervous to try my own programs since I will probably mess up at some point. Can someone reassure me that I won't do any permanent damage? Thanks!
  4. Hi Forum Folks! I just started using a nexys video board on which I want to display some text using its onboard OLED. After doing some research I realized there is no ip for it in vivado ip integrator nor libraries in sdk. I can see there is an example for it using programmable logic but I have to use microblaze. Can anyone point me on how to deal with this? thanks in advance!
  5. Hi, In my project I want to print alphanumeric data on the OLED display on the ZedBoard, but do that by usin GPIO. I have found a couple of related IP cores online, but that is not what I need. I need something simililar like logo.bin file that is the defoult Digilent logo that apears on the OLED when the Linux is booted. So any possibilitis to modify the logo.bin, or to create .bin file with my own contents? I appriciate your tips and help!
  6. Hi there, I am not sure this is the right place to post my inquiry and I am aware that chance to find are very little. I have bought ER-OLEDM024-1 which specs are <a>http://www.displayfuture.com/Display/datasheet/OLED/ER-OLEDM024-1.pdf</a> from www.displayfuture,com . I am trying to control it with AT32UC3L0256 <a>http://www.microchip.com/wwwproducts/en/AT32UC3L0256</a> On the display specs there is a code... if you have any other OLED code sample for that microcontroller , would you mind to pass it to me? Any help will be much appreciated.
  7. Hi Digilent, zedboard, vivado 2015.4, petalinux 2015.4, /dev/zed_oled, pmodoled-gpio.ko I am working on zedboard to enable onboard-OLED display. First vivado outputs bitstream hardware, then petalinux generates " BOOT.BIN + Image.ub ", finally zedboard bootup by the SD card. " insmod pmodoled-gpio.ko " does bring /dev/zed_oled . However, " cat logo.bin > /dev/zed_oled " has nothing to display. Then I decided to add oled block design in vivado project. I tried two different versions, including tamu https://github.com/ama142/ZedboardOLED-v1.0-IP and Digilent
  8. Hi, I'm trying to get the Pmod OLED to work with the PIC24F32KA302, I've used the template file and modified all the register appropriately but I cant get the display to work. It turns on and always display garbage when I try writing to it and even clear the OLED doesn't seem to work, the display does respond to SPI command but just the displays different just pixels. any thoughts on what might be wrong, I can post some code if it helps.
  9. Hello together, I'm a student and I am going to buy the Basys3 board. At that nice student price I thought I'd get a Pmod for Debugging like a little screen. I will be programming only hardware circuits and my own processors. As it seems to me, all tutorials for the OLEDrgb Pmod are made for use with the Microblaze which is not something that I plan to do. For that kind of stuff I already have microcontrollers lying around. I want to be able to access the screen / output (maybe only leds are possible for this purpose? and 7 segments?) directly via my hardware like turning on and
  10. I know, there is great example for Linux application for PmodOled for Zybo. I can find it here. But this is included in Petalinux BSP. If someone is not interested in using Petalinux, then it is painful to install Petalinux just to create project, and extract sources from there. There is another great page about PmodOled - PmodOled reference manual - where I can find link to examples - Example code . Could someone put there link to example for Zybo? Or alternatively, because Zybo example is for whole PmodPack, maybe this code could be put to the page, where there is this BSP file, for exa
  11. Just wondering whether the python module which supports the monochromatic oled display can also drive the rgb one or some re-coding is needed. Thanks for any help, Best, Mario
  12. I'm trying to write a code that will display the character H in the left top corner when the potentiometer is fully counter-clockwise, H in the middle when potentiometer is halfway between ccw and cw, and finally H in the right top corner when potentiometer is fully clockwise. Though my code works, I used a for loop to iterate through all the LEDS before the place where I want to put the H character. I wanted to know how I can change the position of the column number of the Oled. Here's my code: #include<p32xxxx.h> #include<plib.h> #pragma config POSCMOD=HS, FNOSC = PRIPL
  13. Hi, I have recently purchased a few Nexys Video boards. I tried to set up a the XADC demo but the OLED just doesn't work. It just displays garbage on the screen. I have tried building using Vivado 2015.4 & 2015.3 but no luck. I am using PROG-USB port to download the bit file using Vivado Hardware Manager. Is anyone able to built the example design & test it. https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-video-xadc-demo/start If you get it working, please let me know what version of the tool you using. Thank you. Tesh
  14. HI, I am trying to figure out if the OLED Pmod can work with the chipKIT Cmod. Code was taken directly off the Pmod OLED web page. In one version of the demo code -- the Cmod is not mentioned. oledlibrary1 by laraswanland, on Flickr IN a near identical version (on the same page), the Cmod IS mentioned. oledlibrary2 by laraswanland, on Flickr Both demos have OLEDdemo as the sketch. Neither of them work when I have the Pmod OLED plugged into J1 of the Cmod. Can someone take a look at which library is correct? and if the Pmod OLED can work with the Cmod?
  15. Using the PmodOLED and the chipKIT Cmod-- I was able to make the file work on my work-Windows PC I downloaded the newest file from the webpage (thanks to previous post:) and got the library into my sketchbook folder. However, when I tried to compile on my home MacBook, I kept getting this error: Uninstall, reinstall MPIDE. Delete all libraries. Reinstall it again. Then, went to the MPIDE Icon, held down Control+ click and went to "Show Package Contents" Which then I navigated to Contents->MacOSX>Resources>Java>Hardware>pic32>compiler>pic32-tools>include>
