Story

Introduction

Got couple of Raspberry pi pico boards last week. I was curious to try out some example on this pico board. Initially thought about coding with 'c' latest I decide to use micropython. This is going to be my 1st project with micropython.

About Pico

To know about the board details, you can find the spec here. some are

Dual-core Arm Cortex-M0+ processor, flexible clock running up to 133 MHz
264KB on-chip SRAM
2MB on-board QSPI Flash
26 multifunction GPIO pins, including 3 analogue inputs
2 × UART, 2 × SPI controllers, 2 × I2C controllers, 16 × PWM channels
Supported input power 1.8–5.5V DC
Temperature Sensor

The datasheet can be found here

Thonny Python IDE

Thonny IDE is simple coding editor for micropython. Just create new python file (main.py) and write your code then save it on Pico. For more https://thonny.org/

Hardware & Software

I have used the 128x64 size OLED display with I2C interface. This display has the ssd1306 controller. Download the driver from here.

Also used the GPIO Pin GP25 for LED1.

I2C pins SCL=GP9 and SDA=GP8

Just initialize the I2C and send oled picture data (1024 bytes)

i2c = I2C(0) # SCL=Pin(GP9), SDA=Pin(GP8) oled = SSD1306_I2C(WIDTH, HEIGHT, i2c)print("OLED Display Initilized")oled.fill(0)#oled.text("Rasp Pi Pico",1,1)#oled.show()oled.draw_image(logo)

Output

The LED blinks are the rate of 2hz, the OLED displays the picture
