I made a Gameframe by myself. I used the Teensy 3.2 and a microSD adapter. And for coding i purchased your SD-master file. Now i have the issue: It works well for 3-4 days then it begins to create failures on the graphics. Then i checked the SD files and saw the bmp’s were damaged. That means the program create failures on the bmp files after some time. After relaod the files on the sd card everything woks good again but only for some days then it begins to create failures again.
