Re: Where to start STM32H7 support

Hi, I am planning a new (open source) project, an high frequency digital and analog acquisition board, I initially planned to use a F7, but the users insist on having 16 bits ADC, and stm32h7 is one of the few stm32 MCU that offers 16 bits ADC. I follow the quick pace of progress on the H7 side than...

Re: [INFO] Results with GCC 8.2.1 vs GCC 7.3.1

Hi,
My idea is that it is not getting better, I would expect the compiler to improve after all the works that goes into it.


Perhaps it is improving, but at other (higher) level of optimization ?

If it's easy for you, a benchmark with -Ofast would be useful.

Re: My Vcc-gnd.com STM32F407VET6 Mini issues

Hi, After you hit reset and the board hangs, do you have connected a probe to see with gdb (you can attach to a running board) , where, in the init process, it is stuck ? I have had a couple of boards, with out of spec crystal oscillator (or capacitor) which where stuck in the init process in the lo...

Re: My Vcc-gnd.com STM32F407VET6 Mini issues

Hi, [1) these boards use 25MHz osc, which *conf.h values should I change from my usual 8MHz settings? So far I've changed STM32_PLLM_VALUE and STM32_RTCPRE_VALUE from 8 to 25. Are there any more values I would need to change from my typical stm32f4discovery settings? You should probably define STM32...
