a few people have commented that their clocks have either started to display a corrupt screen or nothing when attempting to play one of the many animations.
there's a good chance that you may have lost power while the clock was running (and attempting to write information to the SD card during that power loss) and subsequently, the SD card has become corrupt. this is what you need to do to fix the issue:
steps to fix corrupted SD cards
- browse to https://rundmdimage.wordpress.com/ and download the latest firmware
NOTE: make sure that you are downloading the firmware for the run-dmd EDGE/white boards, not the pico board.
as of 2018.nov.20, the latest version is B134 (fixed image)
- download the application, HDD rawcopy, from here: http://hddguru.com/software/HDD-Raw-Copy-Tool/HDDRawCopy1.10Portable.exe
- run HDD raw copy and select the image file that you downloaded above as the 'source', then click 'ok'
- select the drive letter containing the SD card (don't worry about your computer complaining that the SD card needs to be formatted when you insert it into your reader. information is written to the card without a file allocation table, which is why windows displays this dialog
NOTE: make sure to select the proper drive letter. I take no responsibility for anyone not doing so and formatting a partition of their computer's harddrive
- press the 'OK' button and let raw copy do it's job of re-imaging the SD card
- replace the SD card into your run-dmd clock. you may or may not have to hold down button 3 and re-select the proper display type. you will need to adjust the settings that I preset on everyone's clock including (setting the time, adjusting the brightness, enabling all animations)
these adjustments are saved on the SD card which is why you will lose them after re-imaging the SD card
