Hi,
I am an old programmer (65) and I want to learn how to work with STM32. I live within 10km from ST plants in Crolles (France).Target is to be able to drive signals on a 7' railway layout
English is not my natural language.
For my first step, I bought a STM32F750 Discovery kit. I put in the usb cable and ... it works. I can use the demo apps.
My first question is : can I build a new small program and send it to the board WITHOUT destroying the default apps ?
Second question : when I installed Keil compiler, there was a 'pack installer' window. I could'nt find STM32F750 Discovery kit in it. Can I find it somewhere or do I have to use a 'similar' kit ?
Thanks in advance
Jean
When changing the optimisation level "breaks" code, it is (almost?) invariable the code that is flawed.
It most likely means that you are relying upon something that you should not.
A common example is not having 'volatile' where required.
Another is trying to rely upon the execution time of code.
