Esp32_oscilloscope Arduino firmware turns your ESP32 board into a web-based oscilloscope

Arduino ESP32 Web-based WiFi oscilloscope

Bojan Jurca’s “Esp32_oscilloscope” is an open-source Arduino sketch that can transform an ESP32 board into a web-based oscilloscope that works over WiFi. We had also written about the Scoppy project to turn the Raspberry Pi Pico W into a 2-channel oscilloscope, but there’s no reason the more powerful ESP32-series microcontroller could not be used for the same purpose, and Bojan’s Esp32_oscilloscope project does just that and works with ESP32, ESP32-S2, ESP32-S3 and ESP32-C3 boards using the I2S interface for fast data sampling. The project was initially designed to demonstrate the multitasking abilities of the ESP32 microcontroller with Arduino, but this evolved into an ESP32 oscilloscope firmware. It works both with output/PWM and input signals, digital (0 or 1) and analog (0 to 4095) signals, and the web interface shows up to 736 samples per screen although the sampling rate may not be completely constant all the time. To install it […]

Microchip announces the PolarFire SoC Discovery Kit, a low-cost devkit for Linux and real-time applications

Microchip PolarFire SoC Discovery Kit

The SoC Discovery Kit is the latest addition to Microchip’s list of development kits for the PolarFire series. The series is the first SoC FPGA family powered by a deterministic, coherent RISC-V CPU cluster. They provide low power consumption, thermal efficiency, and defense-grade security for smart, networked systems. They also support a deterministic L2 memory system for Linux and real-time applications. Microchip launched the Icicle Kit for the PolarFire SoC in 2020 and it was followed by the Video and Imaging Kit which was intended for mid-bandwidth imaging and video applications. Now, Microchip has announced the Discovery Kit which is billed as a low-cost alternative to the Icicle. The Discovery Kit retains the full range of features needed for testing concepts quickly, developing firmware applications, and programming/debugging user code. According to Microchip, the kit will bring “a low-cost RISC-V and FPGA development for learning and rapid innovation” to new and […]

SparkFun launches MicroMod Single Pair Ethernet kit for easier 10BASE-T1L experimentation

SparkFun MicroMod Single Pair Ethernet Kit

The SparkFun MicroMod Single Pair Ethernet Kit utilizes the ADIN1110 transceiver for 10BASE-T1L communication, enabling long-distance connectivity over a single twisted pair cable. Things get easier as SparkFun has designed the module to be compatible with the MicroMod ecosystem, which allows for testing connections between industrial devices over long distances, up to 1,700 meters. The standout feature of this board is its ADIN1110 transceiver, which supports 10BASE-T1L Ethernet. This technology uses a single twisted pair for lightweight, long-distance data transmission, achieving speeds up to 10Mbps by the 802.3cg IEEE standard, all without delivering power over the cable. SparkFun MicroMod Single Pair Ethernet Kit Specification: 2x SparkFun MicroMod Single Pair Ethernet Function boards 10BASE-T1L IEEE Standard 802.3cg-2019 Compliant Transceiver Single-pair Ethernet transmission at speeds up to 10Mbps 1km transmission distance (1.7km max cable reach) Supply Voltage of 1.8V or 3.3V 2.4V transmission amplitude Integrated MAC connects via SPI – Supports 16 MAC addresses Supports both […]

Beelink SEi12 i7-12650H mini PC review – Part 2: Windows 11 Pro

Beelink SEi12 i7-12650H mini PC review Windows 11 Pro

We’ve already listed the specs and done an unboxing and teardown for the Beelink SEi12 i7-12650H Mini PC powered by a 10-core Intel Core i7-12650H processor with 32GB DDR4 and a 500GB M.2 SSD preloaded with Windows 11 Pro. In the second part of the review, we will test the Beelink SEi12 i7-12650H with the Windows 11 Pro operating system in detail with a software overview and feature testing, benchmarks, networking and storage testing, thermal efficiency, fan noise, and power consumption. Since we also reviewed the GEEKOM Mini IT12 with the same processor last month, we’ll try to compare both in this review and list the pros and cons for each system. Software overview and features testing The System->About menu confirms that we have a “SEi” Mini PC powered by a 12th Gen 1.5 GHz (base frequency) Intel Core i7-12650H processor and  32GB of RAM, running Windows 11 Pro operating […]

Android 15 Developer Preview released – What’s New?

Android 15

Google has just released the first Android 15 Developer Preview with some improvements related to privacy and security, the addition of the partial screen sharing feature, camera and audio improvements, and some new performance optimization that developers can leverage when running games or other demanding applications. User privacy and security in Android 15 Android 15 features the latest version of the Privacy Sandbox on Android to improve user privacy while enabling personalized advertising experiences for mobile apps, the Heatlth Connect by Android adds support for new data types related to fitness, nutrition, and more, and the File integrity manager implement new APIs making use of the fs-verity feature that was added to the Linux 5.4 kernel so that files can be protected by custom cryptographic signatures. Partial screen sharing is a completely new feature in Android 15 that allows users to share or record an app window rather than the […]

Comparing the latency of various wireless standards

Wireless Latency

If you’ve ever wondered which wireless standard may deliver the smallest lag (latency) when transmitting small packets, we’ve now gotten an answer thanks to Scott at Electric UI who benchmarked various wireless links in common MCU development boards. More specifically the following hardware and wireless standards were tested: SiliconLabs 10×0-GM RF+8051 microcontroller with 240–960 MHz EZRadioPRO transceiver running SiK firmware HopeRF RFM95W LoRa module (on an Adafruit Breakout board) connected to an STM32F429 MCU Nordic Semi nRF24L01 2.4GHz transceiver module ESP32 board for ESP-NOW and WiFi testing is shown as ESP32 WS (WebSockets) or ESP32 TCP in the chart below.
