On the way, another question: when I use STMCWB_full_5.4.1.exe and cubemx6.5.0 to generate the code ,it just stay there and no response.But STMCWB_5.4.8 can work well . Firewell 1.27.0 was used.
I used STMCWB5.4.8.Now I have sloved the problem:my workbench can't find cubemx was because that I habitually rechanged the name of "cubemx.exe" to "cubemx6.5.0.exe"...How can I be so follish?
