Arduino IDE 2.3 released with the Debug feature now considered stable

Arduino IDE 2.3 Debug Feature

Arduino IDE 2.3 has just been released with a range of bug fixes and improvements, but the main change is that the debug feature is not experimental anymore and is now considered stable. Bug fixes include addressing CVE-2023-4863 security flaw (See GitHub for related commits) and based on the wording used in the announcement it looks to be the only one… So the main news is that the Debug feature is now fully incorporated into the IDE. But what is it exactly? The new documentation website explains that Arduino CLI 0.9.0 and Arduino IDE 2.x support “sketch debugging” with openocd server. Arduino also explains it’s currently supported by Arduino boards based on the Mbed core including GIGA R1 WiFi, Portenta H7, Opta, Nano BLE, and Nano RP2040 Connect, and Renesas-based boards such as UNO R4 and Portenta C33 will get support very soon. The company also says they are working […]

Wiser wireless-to-serial kit eases the debugging and programming of embedded devices (Crowdfunding)

WiSer wireless to serial kit

WiSer is a wireless-to-serial communication kit comprised of a USB dongle (WiSer-USB) and a USB TTL debug board (WiSer-TTL) – both built around an ESP32-S2 microcontroller – that allows users to establish a P2P wireless connection between a host computer and a development board or sensor. It works like a typical USB to TTL debug board except it operates over WiFi, and it’s especially useful to debug code, update firmware, log data, or transfer files without a USB cable or even a Wi-Fi router since the connection to peer-to-peer.  It looks especially useful when the host and DUT are too far apart, and my review samples are often on another table around 1.5m from the nearest USB port of my laptop, so I could see some use for it myself… WiSer specifications: Wireless SoC – ESP32-S2 Wi-Fi (and Bluetooth) microcontroller USB – 1x USB Type-C port providing a virtual serial […]

Cologne Chip releases an open-source integrated logic analyser (ILA) for GateMate FPGA chips

Integrated logic analyser ILA Cologne GateMate FPGA

Cologne Chip’s “Integrated logic analyzer” (ILA) project is an open-source Verilog implementation of a logic analyzer running on the company’s GameMate A1 FPGA and designed to capture internal signals. When we first covered the GameMate A1 FPGA we noted Cologne relies on the open-source Yosys framework coupled with a proprietary, but free-of-charge, place & route tool contrary to most other FPGA vendors that only offer closed-source proprietary development tools. The German company has now released the GateMate integrated logic analyzer project to help customers debug their FPGA designs. The project includes the digital circuit of the ILA designed in the hardware description language Verilog and a Python program (ILA Control Program) used to configure the configuration of the ILA from the design under test (DUT) and provide an interface with the user during the debugging process. The user will also need a GateMate FPGA toolchain and GTKWave open-source program to […]

Watch ESP32’s GPIO status in real-time in a web browser

GPIOViewer ESP32 GPIO web browser

GPIOViewer is an open-source Arduino library allowing users to monitor the GPIO pins status of their ESP32 board in real-time in a web browser for troubleshooting or fun. It’s different than the Wokwi ESP32 simulator that works entirely in a web browser since the GPIOViewer library sends GPIO status data of the actual hardware over WiFi to display the pin status as they change in a page rendered in a web browser from a choice of popular ESP32 development boards. The GPIOViewer library relies on the ESPAsyncWebServer Async web server for ESP8266 and ESP32 and the AsyncTCP asynchronous TCP library for ESP32 microcontrollers. The first two must be manually downloaded and installed, and the latter can be installed directly from the Arduino IDE’s Library Manager by searching for it. GPIOViewer has a 50 KB footprint, works with digital, analog, and PWM, and supports various ESP32-VROOM-32 development boards, Olimex ESP32-EVB and […]

PicoUART6 6x UART to USB bridge supports up to 6 Raspberry Pi 5 boards

PicoUART6 Raspberry Pi 5 UART USB bridge

PicoUART6 is a small USB to UART bridge board that takes a Raspberry Pi Pico board and exposes six UART ports to connect up to six Raspberry Pi 5 SBC’s over the new 3-pin UART connector. The Raspberry Pi 5 has created a lot of buzz since its announcement in September 2023, and people most talked about its higher performance compared to a Raspberry Pi 4 and its new (non-standard) FCP PCIe connector,  but the new Raspberry Pi SBC also features a 3-pin JST UART connector that was not used in earlier and frees 3-pin on the 40-pin GPIO header. The PicoUART6 board makes use of this new connector to interface multiple Raspberry Pi 5 over UART and control them through the USB board of the Pico board. PicoUART6 specifications: Footprint for Raspberry Pi Pico board Serial – 6x 3-pin JST UART connectors Expansion – STEMMA QT/Qwiic I2C connector Debugging […]

Ollie v2 USB to UART/CAN/RS485/RS232 converter gets USB-C port, plastic enclosure, and more (Crowdfunding)

USB-C to UART, CAN Bus, RS485, and RS232 converter

Ollie v2 is an improved version of the Ollie USB to isolated UART, CAN Bus, RS232, and RS485 converter that gains a USB-C port, a plastic case, the ability to set the voltage from the target board, and various other minor improvements. Like the first version, the Ollie v2 is a portable tool designed for hackers and field engineers that allows them to work with a single device instead of a bunch of USB converters, each handling a single protocol, and isolation makes sure the host, such as a laptop, is protected from high voltages. Ollie V2 specifications: Serial chip – WCH CH344 quad-serial port chip (instead of XR21V1414 in the first design) Host interface – USB Type-C port Isolated interfaces (all with ESD protection) 2x UART ports up to 6 Mbps with 1.8/3.3/5 V or target voltage levels (set by slide switch) CAN 2.0A/B up to 1 Mbps bus […]

Coin cell-powered boards provide an easy way to test USB-C cables

C2C caberQU USB-C Cable Tester

The A2C caberQU and C2C caberQU boards enable the quick and easy testing of respectively USB-A to USB-C and USB-C to USB-C cables without external hardware. Powered by a CR2032 coin cell battery, the boards apply a voltage to all pins of a cable and measure which ones are connected to the other end. The results can be visualized immediately through various LEDS on the board. The C2C caberQU board comes with a dedicated LED for each of the 24 USB pins and the shield, and it’s possible to test the USB Type-C to USB Type-C cable in several different modes: USB 2.0/1.1 USB Power Delivery USB 3.0/3.1/3.2 Alternate Mode Debug Accessory Mode Audio Adapter Accessory Mode The A2C caberQU board has fewer pins and LEDS for testing USB-A to USB-C cables specifically, but it works the same way. Peter Traunmüller (aka petl) has shot a video showing one of […]
