Develop both chips with Arduino

Develop SenseCAP Indicator both chips with Arduino

The SenseCAP Indicator is a 4-inch touch screen device that is powered by the ESP32 and RP2040 dual MCUs. ESP32 and RP2040 are both highly capable microcontrollers that offer a range of features and functions.

This tutorial will guide you to develop your own custom project/firmware for the Sensecap Indicator using the simplicity and Flexibility of the Arduino Framework.

Hardware Preparation​

I am using SenseCAP Indicator as the hardware here and there are four types of sensors(CO2, Temp, Humi, TVOC) on it. The contents here should include:

Hardware Overview and Develop Knowledge​

The Indicator is designed with two MCU where there are RP2040 and ESP32S3 working at the same time.

Based on the diagram above we know that:

  1. All the sensors are connected to RP2040 Microcontroller using I2C protocol
  2. There is one I2C IO expander module using the PCA9535 IC
  3. The screen are connected to ESP32S3 microcontroller with 2 Pin (CS, RESET) connected to the PCA9535 I2C expander
  4. The RP2040 are connected to the ESP32S3 via pin 20 and pin 19 on the ESP32S3 using UART Interfaces

Thus, if the Sensecap Indicator plugged into the Computer you will be presented with 2 Serial Port one for the RP2040 and one for the ESP32S3. The one with the information USB-SERIAL CH340 is the one that's connected to the ESP32S3 and this is the one will be use for the rest of the tutorial.

Software Preparation​

We are using Arduino here.

Download Arduino IDE
note

Before continuing with the tutorial, make sure the following steps are completed in the Arduino IDE:

  1. ESP32 board definition: Ensure the ESP32 board definition is installed and updated to the latest version. You can follow this guide if the ESP32 board is not yet in the Arduino IDE.
  2. Board selection: Choose the ESP32S3 Dev Module as the board definition.
  3. PSRAM: Enable the OPI PSRAM function in the Arduino IDE to ensure proper functionality of the screen.

Boards Used​

To ensure compatibility with the project, please use the following versions of the boards:

  • ESP32: version 3.1.2
  • Raspberry Pi Pico Arduino: version 4.4.3

Libraries Used​

TouchLib: version 0.0.2

In order to integrate the touch driver and unify the touch interface, TouchLib library is needed. It is not available in the Arduino IDE Library Manager. You can download it manually from the TouchLib GitHub repository, and then add it to the Arduino IDE via Sketch > Include Library > Add .ZIP Library.

After the library is downloaded, open the Arduino IDE, go to the Sketch menu, choose "Add .ZIP Library," and then add the downloaded library into the IDE.

Similarly, for smooth integration, you need to check the same sketch menu and select "Manage Libraries," then search for the required libraries (e.g., "PCA9535," choose the one made by hidea kitai) and install them, while ensuring the following versions for all other required libraries:

  • Adafruit TinyUSB: version 3.4.2
  • Anitracks_PCA95x5: version 0.1.3
  • GFX Library for Arduino: version 1.5.3
  • PacketSerial: version 1.4.0
  • lvgl: version 9.2.2
  • PCA95x5: version 0.1.3

Ensure that these libraries and boards are installed in the Arduino IDE to avoid compatibility issues.

Getting Started​

After all the necessary libraries is installed upload the code below to test if the screen is working with the Arduino environment. You can upload the code below:

#include <Arduino_GFX_Library.h>
#include <PCA95x5.h>
#define GFX_BL DF_GFX_BL // default backlight pin, you may replace DF_GFX_BL to actual backlight pin

/* More dev device declaration: https://github.com/moononournation/Arduino_GFX/wiki/Dev-Device-Declaration */
#if defined(DISPLAY_DEV_KIT)
Arduino_GFX *gfx = create_default_Arduino_GFX();
#else /* !defined(DISPLAY_DEV_KIT) */

// option 1:

Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
    18 /* DE */, 17 /* VSYNC */, 16 /* HSYNC */, 21 /* PCLK */,
    4 /* R0 */, 3 /* R1 */, 2 /* R2 */, 1 /* R3 */, 0 /* R4 */,

Arduino_RGB_Display *gfx = new Arduino_RGB_Display(
    480 /* width */, 480 /* height */, rgbpanel, 2 /* rotation */, true /* auto_flush */,
    bus, GFX_NOT_DEFINED /* RST */, st7701_type1_init_operations, sizeof(st7701_type1_init_operations));

#endif /* !defined(DISPLAY_DEV_KIT) */
/*******************************************************************************
 * End of Arduino_GFX setting
 ******************************************************************************/

void setup(void)
{
  Serial.begin(115200);
  // Serial.setDebugOutput(true);
  // while(!Serial);
  Serial.println("Arduino_GFX Hello World example");

#ifdef GFX_EXTRA_PRE_INIT
  GFX_EXTRA_PRE_INIT();
#endif

  // Init Display
  if (!gfx->begin())
  {
    Serial.println("gfx->begin() failed!");
  }
  gfx->fillScreen(BLACK);

#ifdef GFX_BL
  pinMode(GFX_BL, OUTPUT);
  digitalWrite(GFX_BL, HIGH);
#endif

  gfx->setCursor(10, 10);
  gfx->setTextColor(RED);
  gfx->println("Sensecap Indicator");

  delay(5000); // 5 seconds
}

void loop()
{
  gfx->setCursor(random(gfx->width()), random(gfx->height()));
  gfx->setTextColor(random(0xffff), random(0xffff));
  gfx->setTextSize(random(6) /* x scale */, random(6) /* y scale */, random(2) /* pixel_margin */);
  gfx->println("Sensecap Indicator");

  delay(1000); // 1 second
}

If everything goes well a "Sensecap Indicator" text will be printed randomly on the screen.

Creating Simple GUI Applications with SenseCap Indicator​

The SenseCap Indicator has a powerful ESP32-S3 microcontroller and a high-resolution 480x480 display that makes it ideal for creating graphical user interfaces. Now, we'll continue our development with the SenseCap Indicator by exploring how to create interactive GUI applications using LVGL. You can download the complete project including source code and header files from the repository: Download SenseCap Indicator LVGL Project

After downloading and extracting the project files, upload the following code to create a basic multi-screen GUI application:

The second example builds upon the basic application by adding more sophisticated features including battery monitoring, dynamic data visualization, and color-coded status indicators.

With this code, the SenseCap Indicator will display a three-screen application. Screen1 shows an overview of battery data with color-coded status indicators, Screen2 provides detailed information for individual batteries, and Screen3 offers additional controls or information.
