Sharp Memory Display Not compiling for Arduino 101

[slatedeer]

Hi all, I am in urgent need of help compiling the code for the Sharp Memory Display on my Arduino 101. Any assistance would be greatly appreciated!!

Here's the error message I keep getting:

The reason you're having issues compiling is that you're using a non-avr board and this library has some avr specific code. I was having the same issue with my adafruit feather m0 (arm) in issue #5. Luckily I found a fork of the library at pull request #6. It uses the SPI library so it should be cross platform and thus compile for your board. It compiled for mine.

Thank you so much for your help! I was still getting errors unfortunately, so I did some more searching and tried it again using an older IDE (1.5.6 r-2), and an Arduino Uno instead of a 101, and it worked.... So, the issue now is probably that I need to add the 101 to the list of boards for the Arduino 1.5.6 r-2, but there is no boards manager....if you happen to have any suggestions for that please let me know! Thanks again!

Hi, me again :) So, I abandoned the idea of using an older IDE (apparently the older IDEs do not support adding any new boards) and updated the library per pull request #6 as you suggested. It's now compiling just fine, but I'm getting the following message now: "Starting download script...SUCCESS: Sketch will execute in about 5 seconds." However, I've been sitting here staring at the screen and...no dice. :(

Do you have any suggestions??

Thanks so much again!

I'm guessing you have a wiring problem. You could try crossing your current MISO/MOSI->DI/DO lines.

refactored and fixed SPI - we now use busio.
