Pinout

LCD and the controller

The built-in controller used in this OLED is SSD1305, which has 132 × 64 bit SRAM, supports a maximum 132 × 64 pixels screen, and supports SPI/I2C/8bit 8080 parallel port. The solution of this screen is 128 × 32 pixels, so the internal SRAM is not fully used. This module uses four-wire SPI and I2C interfaces, with good compatibility and high transmission speed.

I2C Communication Protocol

• In I2C communication, a 7-bit slave address + 1-bit read/write bit is sent first, waiting for a response from the device.
• After the slave device responds, it then sends a control byte, which determines whether the bytes sent later are commands or data, and then waits for the slave device to respond.
• After the slave device answers again, if a command is sent, only one byte of the command is sent. If data is sent, only one byte can be sent, or multiple bytes of data can be sent in succession, depending on the situation.

SPI Communication Protocol

• As shown above, the data on SDIN is shifted into an 8-bit shift register on the rising edge of each SCLK in the order of MSB before LSB.
• The D/C# is sampled every 8th clock, and the data in the shift register is written to the Graphics Display Memory (GDDRAM) or Command Register at the same count clock.
• In serial mode, only write operations are allowed. Write operation procedure in 4-wireSPI mode.

Pico User Guide

Hardware connection

Please take care of the direction when you connect Pico, a USB port is printed to indicate. You can also check the pin of Pico and the OLED board when connecting.
You can connect the display according to the table.

OLED	Pico	Description
VCC	VSYS	Power Input
GND	GND	GND
DIN	GP11	MOSI pin of SPI, data transmitted from Master t Slave
CLK	GP10	SCK pin of SPI, clock pin
CS	GP9	Chip selection of SPI, low active
DC	GP8	Data/Command control pin (High:data; Low: command)
RST	GP12	Reset pin, low active
SDA	GP6	I2C data input
SCL	GP7	I2C clock input

Connection (Directly)

Connection(with adapter board)

I2C

As the module adopts SPI by default, you must modify the backside resistor when connecting with an I2C device.

Setup environment

Please refer to Raspberry Pi's guide: https://www.raspberrypi.org/documentation/pico/getting-started/

Download Demo codes

Open terminal and run the following command：

sudo apt-get install p7zip-full
cd ~
sudo wget https://files.waveshare.com/upload/5/5a/Pico_code.7z
7z x Pico_OLED_code.7z -o./Pico_OLED_code
cd ~/Pico_OLED_code
cd c/build/

Run the Demo codes

This guide is based on Raspberry Pi.

C examples

Open a terminal and enter the directory of C codes:

cd ~/Pico_OLED_code/c/

Open main.c and select the corresponding module:

sudo nano main.c 

If the display you use is Pico-OLED-2.23, you need to uncomment the line OLED_2in23_test(). Then press ctrl+c, then press Y and enter to save and exit as follows:

Create a build folder and add SDK:
For example, if the path of SDK is ../../pico-sdk
Then you should create a build and add the path like these:

#mkdir build
cd build
export PICO_SDK_PATH=../../pico-sdk
#export PICO_SDK_PATH=/home/pi/pico/pico-sdk

Run cmake.. command to generate Makefile file.

#Pico
cmake -DPICO_BOARD=pico -DPICO_PLATFORM=rp2040 ..
#Pico2
cmake -DPICO_BOARD=pico2 -DPICO_PLATFORM=rp2350 ..

Run make command to build.

make -j

When the compilation is complete, the uf2 file will be generated inside the build folder. Press and hold the button on the Pico board, connect the Pico to the USB port of the computer via the micro USB cable, and then release the button. Once connected, the computer will automatically recognize a removable disk (RPI-RP2) and copy the uf2 file to the recognized removable disk (RPI-RP2).

#Pico
cp main.uf2 /media/pi/RPI-RP2/
#Pico2
cp main.uf2 /media/pi/RP2350

Python codes

Use in Windows

• 1. Press and hold the BOOTSET button on the Pico board, connect the pico to the USB port of the computer through the Micro USB cable, and release the button after the computer recognizes a removable hard disk (RPI-RP2).
  
• 2. Copy the uf2 file in the python directory to the recognized removable disk (RPI-RP2).
  
  • Pico: rp2-pico-20210418-v1.15.uf2
  • Pico 2: rp2-pcio2-20240809-v1.24.0.uf2
• 3. Open Thonny IDE (Note: Use the latest version of Thonny, otherwise there is no Pico support package, the latest version under Windows is v3.3.3).
  
• 4. Click Tools->Settings->Interpreter, select Pico and the corresponding port as shown in the figure.
  

• 5. File -> Open -> the corresponding .py file, click to run, as shown in the following figure:

Run in Raspberry Pi

• 1. The process of flashing the firmware is the same as on Windows, and you have the option of copying the .uf2 format file into the Pico/Pico2 on your PC or Raspberry Pi.
• 2. Open the Thonny IDE on the Raspberry Pi (click on the Raspberry logo -> Programming -> Thonny Python IDE) and you can view the version information at Help -> About Thonny.
• 3. Open the Thonny IDE in Raspberry Pi, update it if it doesn't support Pico
• 4. Configure the port by choosing MicroPython(Raspberry Pi and ttyACM0 port) in Tools -> Options... -> Interpreter

If your Thonny doesn't support Pico, you can update it with the following command:

sudo apt upgrade thonny

Install Thonny IDE

In order to facilitate the development of Pico/Pico2 boards using MicroPython on a computer, it is recommended to download the Thonny IDE

• Download Thonny IDE and follow the steps to install, the installation packages are all Windows versions, please refer to Thonny's official website for other versions
  • Thonny IDE official download link
  • Thonny IDE download link
  • Thonny official website
• After installation, the language and motherboard environment need to be configured for the first use. Since we are using Pico/Pico2, pay attention to selecting the Raspberry Pi option for the motherboard environment
  

• Configure MicroPython environment and choose Pico/Pico2 port
  
  • Connect Pico/Pico2 to your computer first, and in the lower right corner of Thonny left-click on the configuration environment option --> select Configture interpreter
  • In the pop-up window, select MicroPython (Raspberry Pi Pico), and choose the corresponding port

Flash Firmware

• Click OK to return to the Thonny main interface, download the corresponding firmware library and burn it to the device, and then click the Stop button to display the current environment in the Shell window
• Note: Flashing the Pico2 firmware provided by Micropython may cause the device to be unrecognized, please use the firmware below or in the package
  • Pico firmware library
  • Pico2 firmware library
• How to download the firmware library for Pico/Pico2 in windows: After holding down the BOOT button and connecting to the computer, release the BOOT button, a removable disk will appear on the computer, copy the firmware library into it
