Hello chrysn, The short answer to your question is YES (Please read this mail till end, point 2 is absolutely different way which I think is applicable in my case) 1. The ST property license (www.st.com/SLA0044) in general said that when some portions of software are generated by it's tool(STM32CubeIDE) they should include "reference" for that, which is done by caption table like this included in every beginning of source files: ****************************************************************************** * @attention * * <h2><center>&copy; Copyright (c) 2015 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under Ultimate Liberty license * SLA0044, the "License"; You may not use this file except in compliance with * the License. You may obtain a copy of the License at: * www.st.com/SLA0044 * ****************************************************************************** and that produced code will be run only over ST products ( not Chinese clones). In any case this is that I understand from my long readings over Internet with my poor English. 2. The project "stm32dds" is planed to be completely DIY type. It consist two parts: - one (PCB with STM Device on it) which I discuss above - two - Windows program by which we can START/STOP and configure device This program I plan to put on public repository also - main reason that I don't do this till now is that it is in too early stage i.e. -it open dialog window, connects to COM Port, sends desired wave to device -right on this moment I am working over reading answers from device. To do this I use "Microsoft Visual Studio Community Edition", as driver I use "usbser.sys" and of coarse public available examples from internet what and how to do into coding. If you consider that this is better "applicant" for free PID code I will change GITHIB repository where I keep it from private to public. As last words -> as I wrote above this is completely DIY project. I am Electrical Design Engineer and do this project as hobby in my free time as relax. I don't know when I will finish this project completely. I already achieve main challenge in this project-> to implement DDS signal generation using MCU DMA channel and external R2-R matrix Just as info - this method is about 2.5 faster than build in device DAC (if Device has internal DAC) So for me obtaining own PID is important just only to give this project future live in hands of other hobbyists like me. Because of this I create web site for this project "www.stm32dds.tk" - when project is completely ready I will change content of this site to hold real project compiled sources, schematics and PCB boards manufacturing data.

Thank you very much Scott. It is in my interest to update links to hardware when it is finally ready, so I will. Kind regards Ivan Ivanov На вт, 16.02.2021 г. в 4:45 ч. Scott Shawcroft <notifications@github.com> написа:
