### AI overview

This article describes an ESP32-P4 weather station and air quality monitor built from off-the-shelf boards. It uses a 10.1-inch dashboard, a Sensirion SEN66 multisensor, and LoRa and ESP-NOW sensor nodes, with optional weather data from several APIs and no required cloud account.

### Source excerpt

Harald Kreuzer has built an ESP32-P4 weather station and air quality monitor that features a 10.1-inch dashboard display and a built-in Sensirion SEN66 sensor for particulate matter, CO2, VOC, and NOX, and connects to wireless LoRa and ESP-NOW sensors. The project is entirely made of off-the-shelf boards, so no custom hardware is used, and it should be relatively easy to reproduce. It doesn't require any cloud or user account, although it can connect to a choice of weather APIs (Open-Meteo, OpenWeatherMap or Visual Crossing) to display weather forecasts. The build is fully documented in a long blog post, so we'll highlight the key features of the project in this article. Hardware specifications for the main unit: Based on ESP32-P4-Module-DEV-KIT-C Credit card-sized ESP32-P4-Module-DEV-KIT SBC based on an ESP32-P4NRW32 module with ESP32-P4 with 32MB PSRAM and ESP32-C6 for WiFi and BLE 10.1-inch IPS panel with 1280 x 800 resolution, 800:1 contrast ratio, [...] The post DIY ESP32-P4 weather station & air quality monitor connects to LoRa and ESP-NOW sensors, various weather APIs appeared first on CNX Software - Embedded Systems News.

### AI overview

This tutorial explains how ESP-BIST provides IEC 60730 Class B self-test coverage on Espressif SoCs. It demonstrates an ESP32-P4-powered HMI using an M5Stack Tab5, Modbus communication with a simulated motor controller, and an LVGL touchscreen. The article describes post-boot and runtime tests, safe-state handling, and Host Diagnostics using the low-power RISC-V core.

### Source excerpt

ESP-BIST brings IEC 60730 Class B self-test coverage to Espressif SoCs, and this article walks through what that actually means before putting it to work. Using an ESP32-P4-based M5Stack Tab5 as a Modbus HMI for a simulated motor controller, we show how a SoC that can prove its own health is a chip you can trust to draw a "safe" screen without lying about it.

### AI overview

This article describes implementing a working, PTP-synchronized AES67/RAVENNA audio endpoint on the ESP32-P4 as an ESP-IDF component. It covers clock synchronization, low-latency packet reception, and I2S playout, reporting best-case end-to-end latency of about 0.7 ms and noting which parts are solid or still limited.

### Source excerpt

AES67/RAVENNA is the audio transport behind a lot of broadcast and live-sound infrastructure, and it normally runs on dedicated silicon or Linux boxes. This article is about getting a working, PTP-synchronized AES67 endpoint onto an ESP32-P4 -- how the clock sync, the low-latency receive path, and the I2S playout fit together, what the measured latency is, and where the edges are.
