Actually everything reside in a private repo on the GitLab. All of drawings are uploaded into the files section. Today I almost finished the schematics of analog modules of the device. I'm heavily working on the next version of the curve tracer. The integrated LCD and controls will come in the second iteration.

CIRCUIT BOARD TRACER SOFTWARE

The plan actually, to build the first iteration of the V4 device, completely controllable through the USB port and using a PC software for all of the functions and display.

CIRCUIT BOARD TRACER GENERATOR

The sine wave generator works, I've some USB communication, I've the command interface for the components (the commands still not work via USB, but it is on the way). Actually I'm using the STM32F4-Discovery board for the development, what I already have for years. So I switched the project to F4, to be precise to STM32F407VG.

After many tries, also involving other development boards, it become clear, that the USB code generation of the CubeMX for F3 simply doesn't work (we will see if any suggestions come: ). After this I tried to put together the USB-CDC communication unsuccessfully. With this environment, it started to work almost instantly. After a few days struggling, switched to CubeMX + Atollic TrueStudio. Running the Timer-DMA-DAC as a sine wave generator was unsuccessful. The STM32DUINO is almost unusable when you want to do something deeper hardware related.

I had not too much lack with the selected MCU.ДЇirst I tried to use Arduino for the programming. Hopefully I'll get everything by beginning of the next weekДҐ. So I finally ordered the opamps directly from TI. Unfortunately I had some misunderstanding with Mouser about my companies status, therefore they canceled the order of the TI opamps. All of the components ordered from various sources: Lomex (local), HQElectronics (local), Mouser.

I'm expecting to get them until end of tomorrow.Д¤. I uploaded the updated schematics to the files section (not too much changed)ДЈ. The schematics are changed a bit according to the board routing and some component availability. Here are the pictures of the board designs:Дў. I've finished the PCB design all of the three analog boards together with the PSU.

CIRCUIT BOARD TRACER UPDATE

This log is intend to be a small status update without deep explanation of circuit or software description.ДЎ. The software also in very early stage so please not expect to much from it on the below video.ДЇor the end please watch a little demo of the early demo of the Version 5 Curve Tracer: The analog part is still under development and in designe phase, but there will be not really new stuff in it since SUF and I managed to develop 4 previous versions of Curve Tracers. This is my first PCB which I have ever finnished from designe to manufacturing. I know not everyone likes touch functions, so I aslo added a keyboard woth an encoder wheel. The Version 5 has a 7' lcd with touch, which improves the look of the instrument. Most of the mechanical designes are done as far as the front panel. My main goals was to improve the screen size with adding touch functions. In the mean time I have managed to upgare my little home lab and right away started designing a better version of the original Version 2. Based on most of the feedbacks, everyone wanted to build the Curve Tracer V2, but because of the not so great documentation from my side it was not so easy. The time is here, although this is just an early prototype:ДЄ little while now I have started working on a new version of the original Curve Tracer series.
