Valentine's Pi - Display Your Love

zengirl2

I know you've been wondering what I've been up to.  Despite all the snow, the delivery truck managed to get my sweet display here for my project.  Can you guess what it is?

I'm not telling!  Anyway, she is a beauty and I'm very excited to get her showing love quotes.  As you can see, there are quite a few pins that need to be connected.  In fact, I had to print out a pin chart and also get my magnifying glass out to be sure I had things hooked up properly.  I noticed the screen was white when I received it, and now it has bars.  I'm hoping that is a positive sign; my video background says test bars are a good thingimage.    So, on to the complications of where I am today.  This past week I've been muddling through a tutorial I found for connecting this display to Pi.  I was doing quite well and got all sorts of libraries installed.  However, I came to a grinding halt with an error message.  After trying the entire process again, I realized that I had not made a mistake.  There was something wrong with the commands.  I did some sleuthing at GitHub and found the guy that posted the original info.  Luckily his email was posted, and he swiftly responded to my query.  He said that some lines of commands were missing, which he kindly filled in for me.  So, I made it through a couple more lines with his help, only to get caught again.  We've had about 3 rounds now, but I'm really close to having a working display.  Apparently Chinese New Year had caused him a delay, but today is the day I get to really see if I make it though the entire tutorial.  So, keep your fingers crossed and I promise to have a video when it works.  Otherwise, you will get the Leslie pouting video. image  Actually you all know me too well, and I don't give up.  I'm going to make it easier for the next person to do this.

    The funny part is that I haven't even started hacking code yet.  This is all just Linux commands for connection.  It is apparently the "Year of the Horse" and I'm definitely the stubborn horse in love with Epaper displays. It's going to look so nice to have a white display on a white heart!  Thanks for the encouragement, as always.

    Now that you've let the horse out of the barn (or spilled the cat out of the beans) regarding the kind of display, could you post a link to the display and where you got it?  That could be a fun gadget to play with if the price is reasonable.

  • Hi Leslie,

     

    It looks like you have one of them new fangled electric paper displays.

    It also sounds like you are getting a good lesson in software debugging.  In many ways, it is harder to use someone else's code than your own.  You have to take some time to figure out what they are doing and how they put the code together.  While it is good training, it can also be tedious.

     

    Keep plugging away, we can't wait to see how you complete your project.
