VPC version 3 released!
Finally! VPC looks decent now. - It comes with a full featured "Clock Setup" window of which settings are reflected in the generated code; - Also provided some blink examples, using various clock sources at various frequencies - all blink examples should toggle the LED at 500ms interval. More examples to come - the old … Continue reading VPC version 3 released!
Final version of "Clock setup" window mockup
This is the final version and I think it contains all the elements required to set the frequencies of the STM32L1 clocks regarding to the Nucleo board hardware. I'll work hard to make it functional, but it will depend on my health and time.But now something is obvious: if I want to keep the resolution … Continue reading Final version of "Clock setup" window mockup
Big bug fixed: pll settings
The PLL settings were way off. And that may be the reason why my onewire library didn't worked (is my next test to be done after this fix). Code was committed to the repository.Edited:In the future (version 3?), the clock window configuration will allow much more flexibility - at least, at the CubeMX level. But … Continue reading Big bug fixed: pll settings
