A breathing LED produces a gradual brightening and dimming effect by continuously varying its brightness. In digital hardware, this is accomplished through Pulse Width Modulation (PWM) where the duty cycle is swept from minimum to maximum and back. An FPGA implementation typically splits the design...
I2C Bus Fundamentals The Inter-Integrated Circuit bus (I2C) is a bidirectional two-wire synchronous serial bus that enables communication between integrated circuits. Originally developed by Philips, this serial expansion technology has become ubiquitous in consumer electronics including displays, v...
Implementation Environment Software: Quartus II 13.0 Hardware: MP801 Fundamentals of DDS DDS (Direct Digital Synthesizer) is a digital synthesis technique offering wide relative bandwidth, fast frequency switching, high resolution, and continuous phase. It enables easy digital modulation of frequenc...
FPGA division operations can be implemented using various methods including restoring division, non-restoring division (add-subtract alternation), Goldschmidt's method, and Taylor series expansion. This article presents a straightforward iterative division algorithm along with simulation verificatio...
Clock Configuration for PL-CAN The CAN peripheral clock originates from FCLK-CLK0 in the ZYNQ system. After completing the Vivado block design, this clock value should be verified in the configuration table, which typically shows FCLK-CLK0 at 50 MHz. This value serves as the reference for CAN periph...
System Architecture The design implements a PL-based data generator that transfers sequential counter values to PS DDR via AXI DMA. A GPIO signal from the Processing System triggers the transmission, enabling precise software control over acquisition timing. The data flow originates from a custom RT...
A Synchronous FIFO (First-In, First-Out) is a digital storage structure where data is written and read using a single clock source. This component is essential for buffering data streams between logic blocks that operate within the same clock domain but may process data at different rates. Core Desi...
