Raspberry Pi Pico H - Pico with Headers Soldered

Raspberry Pi Pico H - Pico with Headers Soldered

Overview

The Raspberry Pi Pico H is a microcontroller board that is part of the Raspberry Pi family. It is a low-cost, highly capable device that is ideal for a wide range of applications, including IoT projects, robotics, and embedded systems development. The Pico H variant comes with headers soldered, making it easy to connect to breadboards, protoboards, or other development boards.

Features

RP2040 microcontroller with 264KB of SRAM and 2MB of flash storage
 Dual-core Arm Cortex-M0+ processor
 Flexible I/O options, including GPIO, I2C, SPI, UART, and USB
 Supports high-level languages such as Python and C/C++
 Compatible with Raspberry Pi's official SDK and libraries

Code Examples

Example 1: Blinking an LED using MicroPython

In this example, we will use MicroPython to blink an LED connected to GPIO pin 25 on the Raspberry Pi Pico H.

```
import machine
import utime

# Set up GPIO pin 25 as an output
led = machine.Pin(25, machine.Pin.OUT)

while True:
    # Set the LED high (turn it on)
    led.value(1)
    utime.sleep(1)  # wait for 1 second
    # Set the LED low (turn it off)
    led.value(0)
    utime.sleep(1)  # wait for 1 second
```

Example 2: Reading Analog Input from a Potentiometer using C

In this example, we will use the C programming language to read an analog input from a potentiometer connected to ADC pin 26 on the Raspberry Pi Pico H.

```c
#include <stdio.h>
#include "pico/stdlib.h"
#include "pico/adc.h"

int main() {
    // Initialize the ADC module
    adc_init();
    adc_select_input(0);  // Select ADC pin 26

while (1) {
        // Read the analog input value
        uint16_t adc_value = adc_read();
        printf("ADC value: %u
", adc_value);
        sleep_ms(50);  // wait for 50ms
    }

return 0;
}
```

Example 3: Communicating with a Uart Device using Python

In this example, we will use Python to communicate with a UART device connected to the UART pins (GPIO 0 and 1) on the Raspberry Pi Pico H.

```python
import uart

# Initialize the UART module
uart.init(baudrate=9600, tx=0, rx=1)

while True:
    # Send a string to the UART device
    uart.write("Hello, UART device!")
    utime.sleep_ms(50)  # wait for 50ms

# Read data from the UART device
    data = uart.read(10)  # read up to 10 bytes
    if data:
        print("Received data:", data.decode())
```
