Build a LoRaWAN weighing scale with TTGO T-Weigh ESP32 board, HX711 modules

TTGO T-Weigh

Ever wanted to build your own LoRaWAN connected weighing scale? Me neither, but apparently those types of products already exist for logistics and inventory management, and LilyGO’s latest ESP32 board – the TTGO T-Weigh – is designed for this exact purpose with a Semtech SX1272 based LoRa module, and four HX711 24-bit ADC chips. The board can handle up to four scales that transfer weight data over WiFi, Bluetooth or LoRaWAN, and should be useful in applications that require weighting goods or products where there are limited connectivity options including logistics, farming. TTGO T-Weigh specifications: Wireless modules TTGO T-Micro32 module based on ESP32-PICO-D4 SiP with ESP32 dual-core processor, 4MB SPI flash, 2.4 GHz WiFi 4 and Bluetooth 4.2/5.x TTGO LORA32 module based on Semtech SX1262 transceiver  (EU868/US915)with -22 dBm Tx power, -148 dBm sensitivity, up to 62.5 kbps LoRa bitrate, up to 300 kbps FSK bitrate Antennas WiFi/Bluetooth – Ceramic […]

Getting Started with the Yocto Linux BSP for Polarfire SoC FPGA Icicle Kit

Getting Started Guide PolarFire SoC FPGA Icicle Kit

Last month I received Microchip PolarFire SoC FPGA Icicle development kit that features PolarFire SoC FPGA with a Penta–core 64-bit RISC-V CPU subsystem and an FPGA with 254K LE, and booted it into the pre-installed Linux operating systems based on OpenEmbedded. Today, I’ll show how to get started with the Yocto BSP and run the EEMBC CoreMark benchmark, and I’ll check out the FPGA with Libero SoC Design Suite in a couple of weeks. Operating Systems supported by PolarFire SoC FPGA My initial idea was to focus this part of the review on Linux on RISC-V status, checking some system information, running some benchmarks (e.g. SBC-Bench), compiling the Linux kernel, and installing services like a LEMP stack (Linux, Nginx (pronounced Engine-X), MySQL, PHP) which could be used for WordPress hosting for instance. But then I looked at the operating systems supported with Microchip PolarFire SoC FPGA. There’s a Yocto Linux […]

Pocket P.C. devkits ship, U-blox GNSS module replaced by SIMCom SIM33ELA

Popcorn Computer Shipping

The Pocket P.C. (aka Popcorn Computer) is a handheld Linux computer based on Allwinner A64 with 2GB RAM, 32GB storage, a 4.95-inch Full HD display, and a QWERTY keyboard that was introduced in 2019, and reminds me of PocketCHIP from a few years also with an Allwinner processor, a display, a keyboard, and a battery. The initial plan was to start shipping the device by May 2020, and there are been delays for reasons we’ll explain below, but the good news is that Source Parts has just announced the developer units had been shipped. So what happened exactly, besides the COVID-19 pandemic, government lockdowns, and supply chain disruptions? Source Parts first encountered issues with the quality of PCBs delivered by the manufacturer, which ended up with them having to switch to a new manufacturer. Getting the display to work was also a challenge, and Icenowy, a developer involved with linux-sunxi […]

Open-source Allwinner V3 ISP driver to enable blob-free camera support in mainline Linux

Allwinner V3 ISP Linux driver

Bootlin has just submitted the first patchset for the Allwinner V3 image signal processor (ISP) driver in mainline Linux which should pave the way for a completely open-source, blob-free camera support in Linux using V4L2. There are several blocks in an SoC for camera support including a camera input interface such as MIPI CSI 2 and an ISP to process the raw data into a usable image. Add to this the need to implement the code for sensors, and there’s quite a lot of work to get it all working. Allwinner SDK comes with several binary blobs, aka closed-source binary, but Bootlin is working on making those obsolete, having first worked on Allwinner A31, V3s/V3/S3, and A83T MIPI CSI-2 support for the camera interface driver in the V4L2 framework (and Rockchip PX30, RK1808, RK3128 and RK3288 processors), as well as implemented support for Omnivision OV8865 and OV5648 image sensors earlier […]
