Overview

This module displays a virtual LED strip remote on a touchscreen and handles user interactions through touch inputs. It allows users to control the brightness, color, and effects of an LED strip.

Features

• Touchscreen-based LED strip remote interface.
• Adjustable brightness (0-100%).
• Color selection from a predefined palette.
• Support for effects like strobe, fade, and smooth (to be implemented).

UI Hardware / Pinout Configuration

• Touchscreen Display: 320x240 resolution.
• SPI Configuration:
  • High-speed SPI for drawing: baudrate=40000000.
  • Low-speed SPI for touch: baudrate=2000000.
  • Pins:
    • sck=Pin(7)
    • mosi=Pin(11)
    • miso=Pin(9)
    • dc=Pin(12)
    • cs=Pin(5)
    • rst=Pin(0)
    • Touch chip select: cs=Pin(18).

This image is displayed to the user:

Telemetry Provided

• colorRGB: Current RGB color in the format R,G,B.
• brightness: Current brightness level (0-100).

Telemetry Consumed

None.

Commands Provided

• Brightness adjustment (increase, decrease, on, off).
• Color selection (red, green, blue, white, and additional colors).
• Effects (strobe, fade, smooth).

Examples of Commands Sent

1. Color Selection:

   • If the user presses the "Blue" button, the following command is sent:

     {
       "command": "setColor",
       "value": "0,0,255"
     }
     

2. Brightness Adjustment:

   • If the user increases brightness, the following command is sent:

     {
       "command": "setBrightness",
       "value": 51
     }
     

     (Assuming the brightness was previously at 50 and increased by 1.)
   • If the user decreases brightness, the following command is sent:

     {
       "command": "setBrightness",
       "value": 49
     }
     

     (Assuming the brightness was previously at 50 and decreased by 1.)
   • If the user presses "Off", the following command is sent:

     {
       "command": "setBrightness",
       "value": 0
     }
     

   • If the user presses "On", the following command is sent:

     {
       "command": "setBrightness",
       "value": 100
     }
     

3. Effects:

   • If the user presses "Strobe", "Fade", or "Smooth", placeholder commands are sent (to be implemented):

     {
       "command": "setEffect",
       "value": "strobe"
     }
     

     {
       "command": "setEffect",
       "value": "fade"
     }
     

     {
       "command": "setEffect",
       "value": "smooth"
     }
     

Commands Consumed

None.

Additional Information

• The module uses the color565 function to convert RGB values to 16-bit color format for the display.
• Touch inputs are mapped to specific rows and columns on the touchscreen to determine the selected button.
• Effects like strobe, fade, and smooth are placeholders and need further implementation.
