🌟LilyGO T-Display RP2040🌟

Quick start:

Arduino

1. Open up the Arduino IDE and go to File->Preferences.
2. In the dialog that pops up, enter the following URL in the "Additional Boards Manager URLs" field:

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

3. Go to Tools->Boards->Board Manager in the IDE
4. Type "pico" in the search box and select "Add":
5. Copy TFT_eSPI to the <C:\Users\Your User Name\Documents\Arduino\libraries> directory
6. Open Arduino IDE, find TFT_eSPI in the file and example, the T-Display factory test program is located at TFT_eSPI -> FactoryTest, you can also use other sample programs provided by TFT_eSPI
7. In the Arduino IDE tool options, select the development board Raspbreey Pi Pico, Other keep the default
8. Hold down the BOOT button, click the reset button, and release the BOOT button after a delay of one second or after waiting for the computer to eject a new disk
9. Finally, click upload or drag the firmware to the new disk

MicroPython

1. install Thonny Python IDE
2. After the installation is complete, you need to click on the toolbar, click Run -> Select Interpreter, enter the following interface, select Raspberry Pi Pico, you need to configure Pico before configuring the following ports
3. Press the BOOT button, click RES, then go back to Thonny Python IDE and change the port to the serial port where Pico is located. If you don't find it, click Install or update firmware.
4. Enter or save as a script to run

from machine import Pin, Timer
led = Pin(25,Pin.OUT)
tim = Timer()
def tick(timer):
    global led
    led.toggle()
tim.init(freq=2.5, mode=Timer.PERIODIC, callback=tick)

5. If you need to save to the chip, you need to click File->Save As->rp2040.

6. For more usage methods, please refer to the Micro python documentation.
   
   

Raspberry Pi Pico SDK

The following content is from the introduction of Raspberry Pi Pico SDK.

These instructions are extremely terse, and Linux-based only. For detailed steps, instructions for other platforms, and just in general, we recommend you see Raspberry Pi Pico C/C++ SDK.

1. Install CMake (at least version 3.13), and GCC cross compiler

sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib

2. Set up your project to point to use the Raspberry Pi Pico SDK

• Either by cloning the SDK locally (most common) :

  1. git clone this Raspberry Pi Pico SDK repository

  2. Copy pico_sdk_import.cmake from the SDK into your project directory

  3. Set PICO_SDK_PATH to the SDK location in your environment, or pass it (-DPICO_SDK_PATH=) to cmake later.

  4. Setup a CMakeLists.txt like:

     cmake_minimum_required(VERSION 3.13)
     
     # initialize the SDK based on PICO_SDK_PATH
     # note: this must happen before project()
     include(pico_sdk_import.cmake)
     
     project(my_project)
     
     # initialize the Raspberry Pi Pico SDK
     pico_sdk_init()
     
     # rest of your project
     

• Or with the Raspberry Pi Pico SDK as a submodule :

  1. Clone the SDK as a submodule called pico-sdk

  2. Setup a CMakeLists.txt like:

     cmake_minimum_required(VERSION 3.13)
     
     # initialize pico-sdk from submodule
     # note: this must happen before project()
     include(pico-sdk/pico_sdk_init.cmake)
     
     project(my_project)
     
     # initialize the Raspberry Pi Pico SDK
     pico_sdk_init()
     
     # rest of your project
     

• Or with automatic download from GitHub :

  1. Copy pico_sdk_import.cmake from the SDK into your project directory

  2. Setup a CMakeLists.txt like:

     cmake_minimum_required(VERSION 3.13)
     
     # initialize pico-sdk from GIT
     # (note this can come from environment, CMake cache etc)
     set(PICO_SDK_FETCH_FROM_GIT on)
     
      # pico_sdk_import.cmake is a single file copied from this SDK
      # note: this must happen before project()
      include(pico_sdk_import.cmake)
     
      project(my_project)
     
      # initialize the Raspberry Pi Pico SDK
      pico_sdk_init()
     
      # rest of your project
     

3. Write your code (see pico-examples or the Raspberry Pi Pico C/C++ SDK documentation for more information)

About the simplest you can do is a single source file (e.g. hello_world.c)

#include <stdio.h>
#include "pico/stdlib.h"

int main() {
    setup_default_uart();
    printf("Hello, world!\n");
    return 0;
}

And add the following to your CMakeLists.txt:

add_executable(hello_world
    hello_world.c
)

# Add pico_stdlib library which aggregates commonly used features
target_link_libraries(hello_world pico_stdlib)

# create map/bin/hex/uf2 file in addition to ELF.
pico_add_extra_outputs(hello_world)

Note this example uses the default UART for stdout; if you want to use the default USB see the hello-usb example.

1. Setup a CMake build directory. For example, if not using an IDE:

$ mkdir build
$ cd build
$ cmake ..

1. M>ake your target from the build directory you created.

   $ make hello_world

2. You now have hello_world.elf to load via a debugger, or hello_world.uf2 that >can be installed and run on your Raspberry Pi Pico via drag and drop.
