Red Pitaya STEMlab 125-14 PRO Gen 2 is an AMD Zynq 7010/7020-based board for measurement, control, and signal processing

The Red Pitaya board was first introduced in 2013 as an Xilinx Zynq 7010 SoC FPGA board designed as a high-performance tool acting as an oscilloscope, spectrum analyser, waveform generator, and more. I hadn’t heard about the company much this then, but they must have been doing alright, since Red Pitaya has just started taking pre-orders for the STEMlab 125-14 PRO Gen 2 Starter Kit based on the same AMD Zynq-7010 SoC FPGA, and the STEMlab 125-14 PRO Z7020 Gen 2 Starter Kit with a more powerful Zynq-7020 device. STEMlab 125-14 PRO Gen 2 specifications: SoC FPGA (one or the other) Xilinx Zynq 7010 CPU – Dual-core Cortex-A9 clocked up to 667 MHz FPGA fabric – 28K logic cells, 80x DSP slices Memory – 2.1 Mbit block RAM Xilinx Zynq 7020 CPU – Dual-core Arm Cortex-A9 processor FPGA – 85K logic cells, 220x DSP slices Memory – 4.9 Mbit Block […]

GateMate Integrated Logic Analyzer (ILA) deep dive

CNXSoft: This is a guest article by Dave Fohrn, Embedded Software Engineer at Cologne Chip AG, that goes into detail about the company’s open-source integrated logic analyzer (ILA) for GateMate FPGA chips. A field-programmable gate array (FPGA) is a highly flexible integrated circuit in which complex logic circuits can be configured. They are often used as custom computing units in digital circuits because of their ability to process data quickly and in parallel using individually configured circuits. The digital circuits designed specifically for FPGAs are usually developed in a hardware description language such as Verilog or VHDL and are known as gateware. The term “gate” refers to the configurable digital logic units in the FPGA on which the individual gate circuits are implemented. An effective design can accelerate the computing process by strategically utilizing the various resources available in the FPGA, processing data in parallel, and intelligent implementing pipelining. A […]

Using Raspberry Pi Pico as a logic analyzer

MCU boards, including the $1.5 BluePill board, have been used as cheap logic analyzers for years, notably with Sigrok open-source software. So it should come as no surprise the $4 Raspberry Pi Pico board can also be used as a logic analyzer, with one developer claiming it can deliver 100 Msps, or the performance obtained with a 1.6 GHz CPU, thanks to the PIOs from the Raspberry Pi RP2040. Hackaday reported about a Sigrok driver for the Pico last March, but the topic was brought to our attention via a post on Hackster.io about an open-source Windows program developed from scratch to transform the Raspberry Pi Pico board into a logic analyzer capable of 100 Msps. Agustín Gimenez Bernad (aka gusmanb)’s LogicAnalyzer program offers up to 24 digital channels, pre, and post-trigger sampling, edge trigger and pattern trigger up to 16 bits. It can work with the Raspberry Pi Pico […]
