To use a binary counter in LabVIEW [FPGA](https://www.ampheo.com/c/fpgas-field-programmable-gate-array), you'll design a simple counter that increments a number every clock cycle (or based on an enable signal) using LabVIEW FPGA blocks. Here's a step-by-step guide: ![sddefault (2)](https://hackmd.io/_uploads/rkv0zDhWex.jpg) **What You Need** * LabVIEW FPGA Module * An FPGA-compatible target (e.g., NI myRIO, sbRIO, PXI FPGA card) **Steps to Create a Binary Counter** **1. Open a New FPGA VI** * In your LabVIEW project, right-click the FPGA target → New → VI. * This VI runs on the actual FPGA hardware. **2. Create Counter Logic** **Basic Binary Counter (Free-Running)** 1. Place a Loop: Use a While Loop or Timed Loop to continuously run the counter. 2. Add an Integer Register: * Use a Feedback Node or a Shift Register on the loop boundary. * Set the data type to an appropriate width (e.g., U8, U16, or U32) depending on your required bit width. 3. Increment the Value: * Inside the loop, wire the current value to an Add block and increment by 1. * Feed the result back into the feedback node or shift register. 4. Output the Value: You can wire the output to front panel indicators, DMA FIFO, or digital outputs for debugging or visualization. **Example Logic:** ``` plaintext [Current Count] → +1 → [Next Count] ↑ ↓ (Feedback Node or Shift Register) ``` **3. Optional: Add Enable or Reset** To control the counter: * Enable input: Use a Boolean control to enable/disable counting. * Reset input: Use a button to reset the counter to 0. **Example:** ``` plaintext if (Enable) { if (Reset) count = 0; else count = count + 1; } ``` **4. Compile and Deploy** * Save the FPGA VI. * Click "Run" → "Run on FPGA", or compile and deploy the bitfile to your FPGA target. Note: Compilation can take several minutes depending on the [FPGA](https://www.ampheoelec.de/c/fpgas-field-programmable-gate-array) type. **Summary Table** ![企业微信截图_20250522163510](https://hackmd.io/_uploads/B1_CWv3Wle.png)
