SQLite on STM32F7 series

I'm trying to implement a DataBase connection with STM32F779NIHx. I included the sqlite sources but received an error because the ioctl.h file is not present within the STM32F7XX HAL Driver. Where can I retrieve it?

What's the meaning of this compile/debug error. I didn't have it before.

I made a very simple code following youtube tutorial. I made it work a month ago. I come back and run it in debug mode, it works. I want to make a change in the PWM's length. It doesn't change. I notice the debug mode saying that my source files a ar...

Cycle Counter different when stepping

Hello,I'm currently doing some performance measurements using the DWT's CYCCNT register. As I understand the RM, the CYCCNT counts up for every core clock cycle (except when halted). However, I get different values in CYCCNT when stepping through the...

Is it possible to use the external SRAM or external SDRAM for code space on the STM32F469I-Eval board?

Run code from external RAM

Hello,for a new project I plan to execute the code from an external SRAM connected via FMC.Are there any experience on speed leakage?In an other Topic I read that there are losses of 4 times the speed compared to the embedded Flash.https://community....

resetting the WWDG

Hey everyone,I'm a little confused. I've added the wwdg, but I'm not sure where to refresh it. Is there somewhere I can refresh it that should happen at a constant time, The examples I looked at simply place the reset in the code, but I have so many ...

GPIO Speed

Hello everybody,I have to generate a pulse with very narrow and different widths. The setting and procedure is as follows: Clock Freq = 16 Mhz, Prescaler = 1. off time should be 15 μs,  thuss = 15 μs * 16MHz / 2 = 120  Counts and with this logic for ...
