RP2040-LCD-1.28

RP2040
USB Type-C

Overview

RP2040-LCD-1.28 is a low-cost, high-performance MCU board designed by Waveshare. Although it is tiny, it incorporates a 1.28inch LCD round display, Li-ion battery charger, 6-axis sensor (3-axis accelerometer and 3-axis gyroscope), and so on, adapting all GPIO and Debug headers, which makes it easy for you to develop and integrate it into products quickly.

Feature

RP2040 MCU chip designed by Raspberry Pi in the United Kingdom.
Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz.
264KB of SRAM, and 2MB of onboard Flash memory.
Type-C connector, keeps it up to date, easier to use.
Onboard 1.28-inch 240 x 240 resolution, 65K RGB IPS LCD for clear color pictures.
Lithium battery recharge/discharge header, suitable for mobile devices.
All GPIOs are adapted through 1.27 pitch female headers (There are 30 pins in total, but some pins have been connected to the internal circuit, you need to pay attention when multiplexing, please refer to the wiki for details).
USB 1.1 with device and host support.
Low-power sleep and dormant modes.
Drag-and-drop programming using mass storage over USB.
2 x SPI, 2 x I2C, 2 x UART, 2 x UART, 4 x 12-bit ADC, 16 × controllable PWM channels.
Accurate clock and timer on-chip.
Temperature sensor.
Accelerated floating-point libraries on-chip.
8 x Programmable I/O (PIO) state machines for custom peripheral support.

Install Arduino IDE

Download the Arduino IDE installation package from Arduino website.
Just click on "JUST DOWNLOAD".
Click to install after downloading.
Note: You will be prompted to install the driver during the installation process, we can click Install.

Install Arduino-Pico Core on Arduino IDE

Open Arduino IDE, click the File on the left corner and choose "Preferences".

Add the following link in the additional development board manager URL, then click OK.

https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:

https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.

Upload Demo At the First Time

Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
Click Tool -> Dev Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
After setting, click the right arrow to upload.
- If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE needs to be uninstalled cleanly, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
