* Experiment Objective: Learn how to set up and use SD card for image display and control an RGB lamp.
|
||||
*
|
||||
* Hardware Resources and Pin Assignment:
|
||||
* 1. SD Card Interface --> As configured in SD_Card.h.
|
||||
* 2. Display Interface --> As configured in Display_ST7789.h.
|
||||
* 3. RGB Lamp Interface --> As configured in RGB_lamp.h.
|
||||
*
|
||||
* Experiment Phenomenon:
|
||||
* 1. Runs tests and initializes SD card, display, and sets backlight.
|
||||
* 2. Continuously loops through images on the SD card and controls the RGB lamp.
|
||||
*
