How to power on DE10 FPGA?

 To power on a Terasic DE10 FPGA board, you mainly need the right power source and the correct switch/jumper settings. I’ll cover the common boards (DE10-Nano, DE10-Lite, DE10-Standard). The exact steps are very similar.



1. Identify which DE10 board you have

Look at the silkscreen on the PCB:

  • “DE10-Nano” (with HPS/ARM and RJ45 Ethernet)

  • “DE10-Lite” (small, MAX 10 FPGA, usually used in courses)

  • “DE10-Standard” (larger, Cyclone V, more connectors)

If you’re not sure, follow the section that visually matches what you see.

2. DE10-Nano – how to power it on

The DE10-Nano can be powered in two main ways:

Option A: Via DC barrel jack (recommended for heavy loads)

  1. Use a 5V regulated DC adapter, usually 5V / 2A (check label on board or kit PSU).

  2. Plug the adapter into the DC jack on the board.

  3. Make sure the power select jumper (often labeled JP3 / PWR or similar) is set to DC IN / EXT (depends on revision).

  4. Slide the ON/OFF switch (if present) to ON.

  5. Check:

    • Power LED (often LED1 or PWR) should light.

    • After a second or two, user LEDs may blink if factory demo is loaded.

Option B: Via USB (for light loads / development)

  1. Use a micro-USB cable (typically the “USB-OTG” or “USB-BLASTER II” connector, depending on how the FPGA board is wired for power).

  2. Plug it into:

    • The PC or a USB power source (at least 5V / 1A is safer).

  3. Set the power select jumper to USB (or similar marking).

  4. Turn the power switch to ON.

  5. Confirm the power LED turns on.

Important: Only one power source at a time
Don’t feed the DC jack with 5V and USB power at the same time unless the manual explicitly allows it.

3. DE10-Lite – how to power it on

The DE10-Lite is typically powered via USB:

  1. Find the USB-BLASTER / USB-MINI / USB-MICRO port on the board.

  2. Connect it to your PC using a USB cable.

  3. There may be a power switch (often a tiny slide switch); set it to ON.

  4. Power LED comes on (often labeled PWR or LED1).

  5. Factory demo usually blinks some LEDs on boot.

Some versions may also support an external 5V barrel jack, controlled via a power select jumper (USB vs EXT). If you use an external adapter:

  • Use a 5V regulated adapter of suitable current (e.g., ≥ 1A).

  • Set the jumper to EXT.

  • Turn power ON.

4. DE10-Standard – how to power it on

The DE10-Standard normally uses an external 12V adapter:

  1. Use the supplied 12V DC adapter (often 12V / 2A).

  2. Plug it into the DC jack on the board.

  3. Make sure the power jumper is set to DC / EXT if there are options.

  4. Flip the power switch to ON.

  5. Check the power LED and fans (if any) – they should start.

Some setups also let you power via PCIe or other connectors, but for normal lab use, the barrel jack + switch is the way to go.

5. Common checks if it “doesn’t turn on”

If nothing lights up:

  1. Measure the adapter

    • Use a multimeter to confirm you really have 5V (DE10-Nano/Lite) or 12V (DE10-Standard) at the plug.

  2. Check jumpers

    • Power source selection jumper (USB/EXT, DC/USB, etc.) must match the way you power it.

  3. Check the cable & port

    • Try another USB cable and another USB port / charger.

  4. Look for short circuits

    • If you have wires on the GPIO header, remove them; a short may prevent startup.

  5. Check LEDs

    • If only some LEDs flash quickly then go off, the board may be browning out (not enough current).

6. Quick minimal “power-on” checklist

Regardless of DE10 variant, to power on:

  • Correct power source (5V or 12V as required).

  • Power select jumper matches DC jack vs USB input.

  • Only one power path used at a time.

  • Power switch set to ON.

  • Verify the PWR LED lights up.

  The   STM32 HAL (Hardware Abstraction Layer) Library   provides a structured way to configure and manage the   clock system   in STM32 microcontrollers . The clock system is crucial because it determines the speed at which the CPU, peripherals, and buses operate. This guide explains the   HAL clock initialization process, clock tree, and configuration methods . 1. STM32 Clock Tree Overview The STM32 clock system is highly flexible, allowing multiple clock sources and distribution paths. The main components are: A. Clock Sources Source Description Typical Use HSI  (High-Speed Internal) 8-16 MHz RC oscillator (low accuracy, no external component) Fallback clock, default at startup HSE  (High-Speed External) 4-48 MHz crystal/oscillator (high accuracy) Main system clock, PLL input LSI  (Low-Speed Internal) ~32 kHz RC oscillator (low power, low accuracy) RTC, watchdog timer LSE  (Low-Speed External) 32.768 kHz crystal (high accuracy) RTC, ...

Connecting an STM32 microcontroller to a PC typically involves using a communication interface such as USB , UART (serial) , SPI , or I2C . The most common and straightforward method is through USB or UART . Below, I’ll explain how to connect your STM32 to a PC using these methods. Method 1: Using USB (Direct Connection via Virtual COM Port) Many STM32 boards, such as the STM32 Nucleo or STM32 Discovery series, have a built-in USB-to-serial interface, which allows you to communicate with your PC via a virtual COM port . Steps for Connecting via USB: Use a USB Cable : If your STM32 board has a built-in USB interface (e.g., STM32 Nucleo boards ), simply use a micro-USB or USB-C cable to connect the board to your PC. Install Drivers (if required) : Some STM32 boards (e.g., those with ST-Link or USB to UART interfaces) might require drivers to be installed on your PC. Visit the STMicroelectronics website and download the appropriate ST-Link drivers or Virtual COM Port (VCP) dri...

How do you set up ADC (Analog-to-Digital Converter) in STM32?

图片
  Setting up the   ADC (Analog-to-Digital Converter)   in an STM32 microcontroller involves configuring the ADC peripheral to read analog signals from one or more input channels and convert them into digital values. STM32 microcontrollers have highly flexible ADC peripherals, and the setup process can vary slightly depending on the specific STM32 series (e.g., STM32F1 , STM32F4 , STM32H7 ). Below is a general guide to setting up the ADC in STM32 using   STM32CubeMX   and   HAL (Hardware Abstraction Layer)   libraries. 1.  Hardware Setup Connect the analog signal source (e.g., a sensor or potentiometer) to the ADC input pin on the STM32. Ensure the analog signal voltage is within the ADC's input range (typically 0V to 3.3V for most STM32 devices). 2.  Software Setup Using STM32CubeMX STM32CubeMX is a graphical tool provided by STMicroelectronics to configure STM32 peripherals and generate initialization code. Steps: Open STM32CubeMX: Create...
