🧠Featuring a Raspberry Pi RP2040 microcontroller – what’s it all about?
The RP2040, developed by Raspberry Pi Ltd, is a 32-bit dual-core ARM Cortex-M0+ microcontroller. Introduced in January 2021 as the heart of the Raspberry Pi Pico board, it combines high performance with affordability, making it ideal for both hobbyists and professionals.
🔧 Key Specs:
- Processor: Dual-core ARM Cortex-M0+ @ 133 MHz
- Memory: 264KB SRAM
- Storage: No onboard flash (external flash required)
- I/O: 30 GPIO pins, including SPI, I2C, UART, PWM, and USB 1.1
- Programmable I/O (PIO): 8 state machines for custom peripherals
- Package: QFN-56, 7×7 mm
- Manufacturing Process: 40nm by TSMC
The benefits
As a co-processor, the RP2040 enhances the capabilities of a main processor, such as an x86 or ESP32. It’s commonly found in boards like the LattePanda IOTA, where it supports the main CPU by managing low-level tasks.
🛠️ Co-Processor Roles:
- USB to Serial Conversion: Acts as a dual USB-to-serial bridge
- I2C Slave: Communicates with the main processor to relay sensor data or control signals
- GPIO Expansion: Adds extra I/O capabilities for controlling LEDs, buttons, or other peripherals
- Offloading Tasks: Handles time-sensitive operations like LED blinking or signal generation via PIO, freeing up the main CPU
PIO subsystem
Let’s explore the RP2040’s PIO subsystem, one of its most interesting and unique features is the PIO, or Programmable Input/Output. This hardware subsystem on the RP2040 lets you design custom digital interfaces—such as SPI, I2C, UART, or even VGA—entirely in software, while maintaining hardware-level timing precision.
Rather than depending on the CPU to “bit-bang” signals, which is both slow and imprecise, PIO allows you to create small programs that run on dedicated state machines. This frees up the main processor while providing precise, cycle-accurate control of GPIO pins.
Key Components of PIO
The RP2040 features 2 PIO blocks, each containing 4 state machines, for a total of 8. Each state machine includes:
- GPIO Control: Direct manipulation of pin states
- Instruction Memory: Stores your custom PIO program
- Shift Registers: For serial-to-parallel and parallel-to-serial conversion
- FIFOs: Buffers for sending/receiving data to/from the CPU or DMA
- Clock Divider: Allows precise timing control
💡 Why It’s Game-Changing
- Timing Precision: PIO runs at system clock speed (e.g., 125 MHz), so you get nanosecond-level control.
- CPU Offload: Once programmed, PIO runs independently—no CPU cycles needed.
- Protocol Emulation: You can emulate nearly any digital protocol, even obscure or proprietary ones.
- Parallelism: Multiple state machines can run different programs simultaneously.
What can be accomplished with PIO?
Here are a few practical examples of what PIO makes possible:
| Use Case | Description |
|---|---|
| WS2812 LED Control | Generate precise timing signals for NeoPixel LEDs |
| Custom UART/SPI/I2C | Implement serial protocols not natively supported or with custom behavior |
| Quadrature Encoders | Read rotary encoders with high accuracy |
| VGA Signal Generation | Output video signals directly from GPIO pins |
| PWM with Deadband | Create advanced PWM signals with timing gaps for motor control |
Practical Applications
Powered by the Intel N150 platform’s AI inference capabilities, this board delivers local, real-time intelligence, making it ideal for smart access control, telematics systems, interactive displays, and off-grid monitoring. With its strong performance, extensive connectivity, and dependable design, this SBC is a forward-thinking choice for embedded applications.
With support for ultra-thin eDP touch displays and UPS modules, this board is perfect for portable medical devices, field research kits, and mobile data loggers. It enables developers to quickly prototype and ensures reliable performance, even in tough conditions.
