2Open-source PoE Ethernet GPIB adapter design, compatible with Ethernet and USB-C interfaces
The PoE Ethernet GPIB adapter is designed to connect test equipment equipped with GPIB/HPIB/IEEE-488 interfaces.
The core goal of this project is to provide a convenient solution for connecting multiple GPIB devices via Ethernet, avoiding complicated cable arrangements. Users can choose to use either the Prologix protocol or support for VXI-11.2 (VISA) protocol.
In practical scenarios, commercial-grade Ethernet adapters (each assigned a unique address directly connected to instruments) have elegantly solved these issues. However, such adapters cost around $500, making them impractical for hobbyists. The initial plan was to purchase a single adapter for daisy chaining, but as the number of GPIB devices increased to 20, this plan became unfeasible—hence the emergence of the PoE Ethernet GPIB adapter.

14Software News
(1) Qualcomm releases a new open-source embedded linker tool ELD
The embedded linker plays a critical role in our software stack. While many linkers perform excellently on traditional platforms, they often struggle to meet the unique demands of embedded systems. Embedded projects have unique requirements, such as:
— Highly dependent on linker scripts—this is usually not a concern in host linking— Complex use cases often require customization of linker functionality or linker scripts based on customer needs
To address these challenges, we developed a linker called eld (improved from mclinker). This linker is designed to handle ELF files and aims to meet the unique needs of the embedded field. The eld linker has been incorporated into Qualcomm’s compiler toolchain and reuses LLVM components and libraries as much as possible. Our customers rely on eld to build image systems running on Qualcomm technology hardware.

16 Resolving the stalling issue during MDK compilation, especially noticeable in the new version MDK5.4x
[Source of the problem]
1. Previously encountered this issue while making this video:
[Video tutorial] Avoiding pitfalls, step-by-step guide to using the latest MDK5.42 with STM32CubeMX to create RTX5/FreeRTOS source code projects
2. The phenomenon is that during the compilation process, it gets stuck at a certain position for a long time, ranging from dozens of seconds to several minutes, which is very annoying:
This issue has not been perfectly resolved; earlier attempts to modify the number of processor cores did not yield ideal results.
[Solution]
Later, a kind netizen suggested in the video comments to disable this software and use a dedicated graphics card, which was tested and found to be completely feasible, perfectly resolving the issue. Thanks to this kind netizen.
The setup method is as follows:
Open Windows Settings
Press Win + I to open Settings, enter Graphics Settings in the search bar
Set to use the power-saving version, or when prompted to use the integrated graphics card, use the integrated graphics card.
At the same time, I also disabled the windowed game optimization.
After setting, test MDK again, and the problem is resolved.
17 Progress on H7-TOOL last month
1. Version 2.29 firmware released at the end of April and beginning of May: H7-TOOL firmware 2.29 released, supporting various third-party serial port bridging, RTT automatic reconnection, CAN/RTT/UART independent floating refresh, and adding multiple offline programming options.2. Recently, multiple new offline chip supports have been added again.3. Thanks to the public account: Electronic Development Learning for sharing two articles related to H7-TOOL, very much appreciated, the teardown articles are excellently done, highly recommended. From unboxing to shock: bought an H7-TOOL, after seeing it, I went into a depression!
Teardown of H7-TOOL, how the material pile monster made this universal debugger?
4. The offline programming of H7-TOOL has added a one-click feature to add new chip support, making it more convenient for users to add chip support themselves.
(1) This feature greatly facilitates users in adding chip support themselves.(2) Some chips can be used directly after being added this way, but some chips require adjustments and modifications based on this. Overall, this is a very practical feature.
Previously released V1.0 operation instructions, the next version 2.30 will upgrade this part again, automatically filling in file names, Flash addresses, Flash sizes, SRAM addresses, and SRAM sizes.
5. Testing the signal generator load capacity of H7-TOOL There are detailed testing posts in the forum. If the application requires the signal generator to drive devices, attention should be paid to the driving capacity. The signal generator’s amplitude range is -10V to +10V, supporting arbitrary waveforms. If the actual measured amplitude is much lower than the set value, it indicates that the load consumption is slightly large.
6. Automatic segmentation range setting method for offline programming of H7-TOOL for large non-continuous hex files There are detailed operation instruction posts in the forum.(1) For example, if the chip capacity is 1MB, but the actual program size is only a few KB, but some data is stored in the last sector attribute of the 1MB program, causing the hex2bin.exe file to be very large, nearly 1MB, this situation can be considered for segmentation, which can greatly speed up the download speed without downloading so much unused space in between.(2) There are also mixed programs of internal Flash and external Flash, due to the large range span, the TOOL can conveniently auto-segment without requiring users to set the range themselves. Of course, if the span is relatively small, manual segmentation can also be considered.
