Hi,I want to place parts of code in ITCM (using IAR). The manual (IAR ARM Development Guide), as I could find, has instructions only for general case when you put all the code in RAM. But my app does not fit in ITCM, so I need a way to specify which ...

Hello,I've not much experience with all STM timer modes. I have a DDS-based freq source which produces meander wave. On base of this src I want to produce PWM signal using STM timer. As I understand, a regular way to do it is to pass the DDS src as e...

Hello!For some time already I cannot find this in manuals. Can someone point me if there is any table somewhere? Of course I can find it out experimentally, but it would be more convenient to know where it is listed.

Hello everyone,I'm using USART3 on F746, but only RX/TX pins which are mapped to pins PD8/PD9.Besides that, I want to configure general output to pins PD10/PD11 (to control LEDs), but they don't work when I try to control them. I looked up the AF map...

I'm trying to run AES CCM encryption on STM32F746G-Disco board in hw-accelerated mode. Tried to use CryptoLib 3.1.2 and low level Examples from 756-Eval board. For some reason there is no working example supplied by ST that implements this mode with ...

One more question: you say that we must put this channel in input mode. But then how do I get putput signal - can one channel act as input and output simultaneously?

Thank you for the guide! The matter is I'm not familiar with direct register programming, but used to deal with HAL instead. So I'm not sure how to implement your steps using HAL. Is it possible to configure it through HAL calls?As for now, I have th...

Thank you very much! For sure I wouldn't find this place myself :)).

I also encountered this problem - not being able to see any MOSI signal running SPI_FullDuplex_ComDMA example in Master mode. In fact, it's very embarassing! Using framework v.1.8.0. Scott, did you manage to get your project working?

Thank you for your efforts to help me with this! Today I tried to reproduce it, but didn't succeed as well. You were right, it works without modification either. I rolled back to the code that didn't work and finally found out the real reason for tha...
