wheather forecaster with Infineon CY8CKIT-041-41XX PSoC™ 410

Connect the sensors to the Pioneer Kit
Connect the DHT11 temperature and humidity sensor to the Pioneer Kit as follows:

• VCC to 5V
• GND to GND
• Data pin to P10[0] pin of the Pioneer Kit

Connect the BMP180 barometric pressure sensor to the Pioneer Kit as follows:

• VCC to 3.3V
• GND to GND
• SDA to P12[0]
• SCL to P12[1]

Connect the 2x16 LCD display to the Pioneer Kit as follows:

• VSS to GND
• VDD to 5V
• RS to P0[1]
• RW to GND
• E to P0[0]
• D4 to P0[4]
• D5 to P0[5]
• D6 to P0[6]
• D7 to P0[7]
• A to 5V
• K to GND

Create a new project in PSoC Creator Create a new project in PSoC Creator and add the following components:

• UART
• I2C Master
• LCD
• DHT11
• BMP180

Configure the componentsConfigure the UART component to 115200 baud rate and connect it to the PSoC Kit's USB-UART bridge. Configure the I2C Master component to use P12[0] as SDA and P12[1] as SCL. Configure the LCD component to use 2x16 display and connect it to the corresponding pins.

Step 4: Write the codeHere's the code for the weather forecaster:

#include "project.h"
#include "stdio.h"
#include "stdlib.h"
#include "DHT11.h"
#include "BMP180.h"

int main(void)
{
    CyGlobalIntEnable; /* Enable global interrupts. */

    UART_Start(); /* Start the UART component */
    LCD_Start(); /* Start the LCD component */
    DHT11_Start(); /* Start the DHT11 component */
    BMP180_Start(); /* Start the BMP180 component */
    
    float temperature, humidity, pressure;
    char str[16];
    
    for(;;)
    {
        if(DHT11_GetStatus() == DHT11_READY)
        {
            temperature = DHT11_GetTemperature();
            humidity = DHT11_GetHumidity();
        }
        
        if(BMP180_GetStatus() == BMP180_READY)
        {
            pressure = BMP180_GetPressure();
        }
        
        sprintf(str, "Temp: %.1f C", temperature);
        LCD_Position(0,0);
        LCD_PrintString(str);
        
        sprintf(str, "Humidity: %.1f%%", humidity);
        LCD_Position(1,0);
        LCD_PrintString(str);
        
        sprintf(str, "Pressure: %.1f kPa", pressure/1000);
        UART_PutString(str);
        
        CyDelay(5000);
    }
