I have a Nucleo board for motor control applications, and I would like to try the PIL with Simulink. I am reading a bit, and I found and installed the STM32 embedded target. In Simulink Library Browser, I can see now the "Simulink Coder Support Package for STMicroelectronics Nucleo Boards". Keeping on with my reading online, I found this article (from 2015) MATLAB Simulink design workflow for STM32F4 with a video. In the video, I can see that the library browser offers the "Target Support Package - SMT32F4xx Adapter" (5:26 in the video). I was looking for it in the Add-ons but I could not find it.
So my question is: is there a Target Support Package for SMT32F3 or F4 available, or is it no longer supported?
