|
|
||
|  | ||
| ## Features | ||
|
|
||
| - **Processor**: Dual-core Arm Cortex-M0+ RP2040. | ||
| - **Buttons**: Boot and Reset buttons for easy programming and reset. | ||
| - **GPIO**: Processor pins are exposed on double header pins for flexible connectivity. | ||
| - **LED**: An LED connected via a transistor on pin 25 for status indication. | ||

|
|
||
| ## Processor Details | ||
|
|
||
| The RP2040 processor, developed by the Raspberry Pi Foundation, is a versatile microcontroller that includes the following key features: | ||
|
|
||
| - **Architecture**: Dual-core Arm Cortex-M0+. | ||
| - **Clock Speed**: Up to 133 MHz. | ||
| - **Memory**: 264KB of SRAM, and support for up to 16MB of external QSPI flash memory. | ||
| - **GPIO**: 30 GPIO pins, including a rich set of I/O options like UART, SPI, I2C, PWM, and ADC. | ||
| - **Timers**: Multiple timers and a real-time clock (RTC). | ||
| - **DMA**: Direct Memory Access controller for efficient data transfer. | ||
| - **Debugging**: SWD (Serial Wire Debug) interface for debugging and development. | ||
|
|
||
| ## Programming Options | ||
|
|
||
| The RP2040 microcontroller offers multiple programming options, providing flexibility for various types of developers: | ||
|
|
||
| 1. **MicroPython**: | ||
| - An easy-to-use Python interpreter ideal for beginners. | ||
| - Allows rapid prototyping and development with an extensive set of libraries. | ||
|
|
||
|
|
||
| 2. **C/C++ with the Pico SDK**: | ||
| - Provides low-level access to the hardware for maximum performance. | ||
| - Suitable for more complex projects and experienced developers. | ||
| - Requires setting up the Pico SDK and toolchain on your development environment. | ||
|
|
||
| 3. **Arduino IDE**: | ||
| - Offers a familiar environment for those used to Arduino development. | ||
| - Supports both the Mbed OS core and the C/C++ SDK-based core. | ||
| - Simplifies the process of writing, compiling, and uploading sketches to the RP2040. | ||
|
|
||
| ### Drag-and-Drop Programming: | ||
| - Allows you to upload firmware by simply dragging and dropping a UF2 file. | ||
| - Useful for quick updates and easy deployment without needing an IDE. | ||
|
|
||
| ## Usage | ||
|
|
||
| 1. **Flashing Firmware**: | ||
| - Hold the Boot button and press the Reset button. | ||
| - Release the Reset button while still holding the Boot button to enter bootloader mode. | ||
| - Drag and drop the firmware file onto the USB drive that appears. | ||
|
|
||
| 2. **Programming**: | ||
| - Use your preferred IDE (e.g., Thonny, VS Code, Arduino IDE) and select the appropriate board and port. | ||
| - Write your code and upload it to the RP2040. | ||
|
