- | ====== Functional Description ====== | ||
- | |||
- | The Pmod MTDS has an on-board PIC32MZ microncontroller that is running the MTDS firmware. To communicate with the device, you must use the MTDS and MyDisp libraries available and documented on the [[software: | ||
- | |||
- | JP1 is used to select how to power the display' | ||
- | |||
- | The microSD connector allows the MTDS firmware to draw and save images to an attached microSD card. In order to work properly, the microSD card must be formatted as FAT32. Image files should be saved as Windows Bitmap files (.bmp). For more information see the MTDS documentation available on the [[software: | ||
