High-speed data acquisition with Raspberry Pi Pico 2’s HSTX interface and HDMI to USB 3.0 video capture dongle

We previously explained the HSTX high-speed serial transmit interface of the Raspberry Pi RP2350 microcontroller was mostly useful for video outputs and display interfaces since it can only transmit, and not receive data. But Steve Markgraf found another use case for the HSTX interface – high-speed data acquisition – combining a Raspberry Pi Pico 2 board with the DVI Sock board for Pico and one of those cheap MS2130-based HDMI to USB 3.0 video capture dongles. He managed to stream out up to 75 MB/s of real-time data from an overclocked RP2350 to a host computer with a USB 3.0 port. The Adafruit Feather RP2350 HSTX board should also work, but also not been tested. Steve’s “hsdaoh-rp2350” data acquisition over HDMI firmware is based on the dvi_out_hstx_encoder example from Raspberry Pi using the HSTX interface for DVI output and code by Shuichi Takano implementing the HDMI data island encoding required […]

Giveaway Week 2024 – Elecrow 7-inch CrowVision touchscreen display for Raspberry Pi and other SBCs

It’s already day 6 of CNX Software’s Giveaway Week 2024, and the prize is the Elecrow 7-inch CrowVision touchscreen display designed for Raspberry Pi boards and other single board computers (SBC). Elecrow sent us a sample of the touchscreen display last year to review “whenever we have time”. But it turns out that finding time is tricky, so instead of getting it to waste, I decided to give it away to one lucky reader of CNX Software. Elecrow CrowVision 7-inch display specifications: Type – 7-inch IPS display Resolution – 1024×600 Multitouch – 5-point capacitive touchscreen Viewing angle – 178° Video Input – Mini HDMI connector USB – Micro USB port for touchscreen function Audio 3.5mm audio jack for headphones Speaker connector User input – Touchscreen and keypad interface for provided 5-key board Power Supply 12V/2A DC input via power barrel jack 5V DC output via USB Type-A port Dimensions – […]

1.28-inch round color display features Raspberry Pi RP2350, motion sensor, GPIO headers, metal case

Waveshare has recently launched the RP2350-LCD-1.28, a Raspberry Pi RP2350-based 1.28-inch round color display module with 240×240 pixel resolution and a 65K-color IPS panel. This board also features a rechargeable Lithium battery manager, a 6-axis IMU with a 3-axis gyroscope and accelerometer, multiple GPIO pins, and a USB Type-C connector for programming and power. Additionally, it supports USB 1.1 host/device support, temperature sensor, and 24 PWM channels, all configured for flexible I/O options. These features make this device useful for IoT, wearable tech, and embedded applications. The company also provides an optional CNC metal casing that provides durability and heat dissipation for portable or rugged applications. We have previously covered similar development boards with a round display such as the RP2040-powered 0.99″ rounded display, the ESP32-S3 LCD Driver Board, the SB-Components has launched Dual Roundy, and others, but it’s the first to feature the RP2350 microcontroller.
