Smart Panlee SC01 Plus BSP Example

This example demonstrates the core functionality of the espp::SmartPanleeSc01Plus BSP component on the Smart Panlee SC01 Plus touchscreen display module.

Features Demonstrated

  • ST7796 display initialization over the ESP32-S3 8-bit parallel LCD bus

  • FT5x06 touch handling with LVGL integration

  • Foreground custom-drawn touch trail with bounded invalidation for smooth redraws

  • I2S speaker playback with a bundled touch-click sound, plus an on-screen audio row (bottom-left) to play the sound, toggle mute, and adjust the volume

  • Backlight brightness control

  • Optional microSD mounting and filesystem inspection

  • Published peripheral pin maps for I2S, RS-485, and external GPIOs

  • Rotation-aware UI layout with wrapped instructions that stay on-screen in portrait/landscape

Configuration notes

This example raises some espp BSP task stack sizes above their component defaults via sdkconfig.defaults, because the example does more work in those tasks than the defaults assume:

  • Interrupt / touch task stack (CONFIG_SMARTPANLEE_SC01_PLUS_INTERRUPT_STACK_SIZE = 8192, up from the 4 KB BSP default). The interrupt task services the touch controller over I2C; if an I2C transaction errors, the error is logged through espp’s fmt-based (colorized) logger, whose formatting path needs several KB of stack. With only 4 KB this can overflow and corrupt memory. If you base your own project on this example (or reproduce its functionality), keep this override in your sdkconfig / sdkconfig.defaults.

Hardware Required

  • Smart Panlee SC01 Plus / WT32-SC01-PLUS compatible board

  • USB-C cable for programming and power

  • microSD card (optional)

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output and verify that touching the screen draws circles and plays the embedded click sound. The refresh button rotates the display and the label will reflow to stay within the visible screen width:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)
