# RP2040-ETH WS2812 Network Control
|
||||
|
||||
This implementation adds ethernet connectivity to the WS2812 LED control, allowing you to control the LED color over the network.
|
||||
|
||||
## Hardware Setup
|
||||
|
||||
- **Board**: Waveshare RP2040-ETH
|
||||
- **LED**: WS2812 connected to GPIO 25
|
||||
- **Ethernet**: CH9120 chip handles TCP/IP communication
|
||||
|
||||
## Network Configuration
|
||||
|
||||
Default settings (can be modified in `ch9120.c`):
|
||||
- **IP Address**: 192.168.1.200
|
||||
- **Port**: 1000
|
||||
- **Mode**: TCP Client
|
||||
- **Target IP**: 192.168.1.10
|
||||
- **Target Port**: 2000
|
||||
|
||||
## Building
|
||||
|
||||
```bash
|
||||
cd build
|
||||
cmake ..
|
||||
make barnum_eth
|
||||
```
|
||||
|
||||
## Flashing
|
||||
|
||||
1. Hold BOOTSEL button and connect USB
|
||||
2. Copy `barnum_eth.uf2` to the RPI-RP2 drive
|
||||
3. The board will reboot automatically
|
||||
|
||||
## Usage
|
||||
|
||||
### Supported Commands
|
||||
|
||||
Send these commands as TCP messages to control the LED:
|
||||
- `RED` - Set LED to red
|
||||
- `GREEN` - Set LED to green
|
||||
- `BLUE` - Set LED to blue
|
||||
- `WHITE` - Set LED to white
|
||||
- `OFF` - Turn LED off
|
||||
- `RGB:r,g,b` - Set custom color (e.g., `RGB:255,128,0` for orange)
|
||||
|
||||
### Python Test Client
|
||||
|
||||
Use the included `test_client.py` to test:
|
||||
|
||||
```bash
|
||||
# Run demo sequence
|
||||
python3 test_client.py
|
||||
|
||||
# Send single command
|
||||
python3 test_client.py "RGB:255,0,255"
|
||||
```
|
||||
|
||||
### Features
|
||||
|
||||
- Smooth color transitions between commands
|
||||
- Network status feedback via USB serial
|
||||
- Acknowledgment messages for each command
|
||||
|
||||
## Pin Assignments
|
||||
|
||||
- **WS2812 Data**: GPIO 25
|
||||
- **UART TX (CH9120)**: GPIO 20
|
||||
- **UART RX (CH9120)**: GPIO 21
|
||||
- **CFG (CH9120)**: GPIO 18
|
||||
- **RES (CH9120)**: GPIO 19
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
1. **No network connection**:
|
||||
- Check ethernet cable is connected
|
||||
- Verify IP settings match your network
|
||||
- Use serial monitor to see debug output
|
||||
|
||||
2. **LED not responding**:
|
||||
- Verify WS2812 is connected to GPIO 25
|
||||
- Check power supply to LED
|
||||
- Monitor serial output for errors
|
||||
|
||||
3. **Can't flash the board**:
|
||||
- Make sure to use the correct board setting in CMakeLists.txt
|
||||
- The board type is already set to `waveshare_rp2040_eth`

这个文件是帮助您使用本例程。
|
||||
由于我们的LCD越来越多，不便于我们的维护，因此把所有的LCD程序做成一个工程。
|
||||
在这里简略的描述本工程的使用：
|
||||
|
||||
1.基本信息：
|
||||
本例程用于测试或者演示RP2040-ETH上WS2812B;
|
||||
|
||||
2.管脚连接：
|
||||
DIN -> 25
|
||||
|
||||
3.基本使用：
|
||||
你需要执行：
|
||||
如果目录已经存在，则可以直接进入。 如果没有目录，执行:
|
||||
mkdir build
|
||||
进入目录，并添加SDK:
|
||||
cd build
|
||||
export PICO_SDK_PATH=../../pico-sdk
|
||||
其中 ../../pico-sdk 是你的SDK的目录。
|
||||
执行cmake，自动生成Makefile文件:
|
||||
cmake ..
|
||||
执行make生成可执行文件，然后在终端中输入：
|
||||
make
|
||||
编译好的uf2文件复制到pico中即可

This file is to help you use this routine.
|
||||
Since our ink screens are getting more and more, it is not convenient for our maintenance, so all the ink screen programs are made into one project.
|
||||
A brief description of the use of this project is here:
|
||||
|
||||
1. Basic information:
|
||||
This routine is used to test or demonstrate WS2812B on RP2040-ETH.
|
||||
|
||||
2. Pin connection:
|
||||
Pin connection You can look at dev_config.c/h in \lib\Config. Again, here:
|
||||
DIN -> 25
|
||||
|
||||
3. Basic use:
|
||||
You need to execute:
|
||||
If the directory already exists, you can go directly. If there is no build directory, execute
|
||||
mkdir build
|
||||
Enter the build directory and type in the terminal:
|
||||
cd build
|
||||
export PICO_SDK_PATH=../../pico-sdk
|
||||
Where ../../pico-sdk is your installed SDK directory
|
||||
Execute cmake, automatically generate Makefile file, enter in the terminal:
|
||||
cmake ..
|
||||
Execute make to generate an executable file, and enter in the terminal:
|
||||
make
|
||||
Copy the compiled uf2 file to pico

这个文件是帮助您使用本例程。
|
||||
在这里简略的描述本工程的使用：
|
||||
|
||||
1.基本信息：
|
||||
本例程用于测试或者演示RP2040-Zero上WS2812B;
|
||||
|
||||
2.管脚连接：
|
||||
管脚连接你可以在RP2040-Zero.py查看，这里也再重述一次：
|
||||
DIN -> 16
|
||||
|
||||
3.基本使用：
|
||||
1): 按住RP2040-Zero板上的Boot按键，将RP2040-Zero通过Type-C USB线接到电脑的USB接口，然后松开按键。
|
||||
接入之后，电脑会自动识别到一个可移动盘（RPI-RP2）
|
||||
|
||||
2): 将Python目录下的uf2文件夹中rp2-pico-20210902-v1.17.uf2 文件复制到识别的可移动盘（RPI-RP2）中
|
||||
|
||||
3): 更新Thonny IDE
|
||||
sudo apt upgrade thonny
|
||||
|
||||
4): 打开Thonny IDE （点击树莓logo -> Programming -> Thonny Python IDE ）
|
||||
选择Tools -> Options... -> Interpreter
|
||||
选择MicroPython(Raspberry Pi Pico 和ttyACM0端口
|
||||
|
||||
5): 在Thonny IDE中打开Python/RP2040-Zero.py文件
|
||||
然后运行当前脚本（绿色小三角）即可

After connecting, the computer will automatically recognize a removable disk (RPI-RP2)
|
||||
|
||||
2): Copy the rp2-Pico-20210902-v1.17.uf2 file from the Uf2 folder in the Python directory to an identified
|
||||
removable disk (rpi-rp2)
|
||||
|
||||
3): Update Thonny IDE
|
||||
sudo apt upgrade thonny
|
||||
|
||||
4): Open Thonny IDE （Click raspberry logo -> Programming -> Thonny Python IDE ）
|
||||
select Tools -> Options... -> Interpreter
|
||||
select MicroPython(Raspberry Pi Pico and ttyACM0 port
|
||||

# RP2040-ETH Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
The Waveshare RP2040-ETH is a compact microcontroller board that combines the Raspberry Pi RP2040 chip with built-in Ethernet connectivity. It provides a powerful dual-core processor with integrated networking capabilities in a small form factor.
|
||||
|
||||
## Hardware Specifications
|
||||
|
||||

|
||||
- **Clock Speed**: Flexible clock up to 133 MHz
|
||||
- **Memory**: 264KB SRAM
|
||||
- **Storage**: 4MB onboard Flash memory (W25Q32JVSSIQ NOR-Flash)
|
||||
|
||||
### Ethernet
|
||||
- **Ethernet Chip**: CH9120 with integrated TCP/IP protocol stack
|
||||

|
||||
- TCP Server/Client modes
|
||||
- UDP Server/Client modes
|
||||

|
||||
|
||||
## Programming the RP2040-ETH
|
||||
|
||||
### Development Options
|
||||
- C/C++ SDK
|
||||
- MicroPython
|
||||
- Arduino IDE
|
||||
|
||||
### What We've Learned
|
||||
|
||||
From our WS2812 LED control implementation:
|
||||
|
||||
1. **PIO Usage**: The RP2040's PIO (Programmable I/O) is excellent for timing-critical operations like WS2812 LED control. We used PIO0 with state machine 0 to generate precise timing signals.
|
||||
|
||||
2. **Clock Configuration**: The default system clock works well for most applications. We commented out `set_sys_clock_48()` as it wasn't necessary for our WS2812 implementation.
|
||||
|
||||
3. **Pin Mapping**: GPIO 25 was used for WS2812 data output in our example, demonstrating the flexibility of pin assignment on the RP2040.
|
||||
|
||||
4. **Timing Precision**: The PIO handles the 800kHz timing requirement of WS2812 LEDs perfectly, showing the RP2040's capability for real-time signal generation.
|
||||
|
||||
5. **Memory Efficiency**: With 264KB of SRAM, there's plenty of room for complex applications beyond simple LED control.
|
||||
|
||||
### Code Structure Example
|
||||
|
||||
Our WS2812 implementation demonstrates key RP2040 programming patterns:
|
||||
|
||||
```c
|
||||
// PIO initialization
|
||||
PIO pio = pio0;
|
||||
int sm = 0;
|
||||
uint offset = pio_add_program(pio, &ws2812_program);
|
||||
ws2812_program_init(pio, sm, offset, 25, 800000, true);
|
||||
|
||||
// Color data formatting (GRB format for WS2812)
|
||||
uint32_t mask = (green << 16) | (red << 8) | (blue << 0);
|
||||
put_pixel(mask);
|
||||
```
|
||||
|
||||
### Key Takeaways
|
||||
|
||||
1. **Hardware Abstraction**: The Pico SDK provides excellent hardware abstraction layers, making it easy to work with complex peripherals.
|
||||
|
||||
2. **PIO Power**: The programmable I/O blocks are one of the RP2040's strongest features, enabling precise timing without CPU intervention.
|
||||
|
||||
3. **Development Workflow**: The USB mass storage programming mode makes development iteration very fast - just drag and drop the UF2 file.
|
||||
|
||||
4. **Ethernet Integration**: While our example doesn't use Ethernet, the CH9120 chip provides a straightforward path to network connectivity without complex TCP/IP stack implementation.
|
||||
|
||||
## Future Considerations
|
||||
|
||||
- The Ethernet functionality via CH9120 opens possibilities for IoT applications
|
||||
- The dual-core processor allows for concurrent tasks (e.g., LED animation on one core, network communication on the other)
|
||||
- The castellated edges make this board ideal for integration into custom PCBs
|
||||
- PIO state machines can be used for various protocols beyond WS2812 (SPI, I2C variants, custom protocols)
