Hi,I am developing an application running on STM32H743II MCU and I need to use all the 1Mbyte RAM.I tried to define a RAM_region for every SRAMx, this didn't work properly and not managed to build the project successfully.Another issue is that some ...
hello everyone, I have a problem in communication 2 slaves and 1 master using SPI.master will send a code to activate one of the slaves and then the master will receive data from the slave, but sending the initial data is always wrong and only when t...
I am currently using STM32F746. I am trying to exit from a MemManage fault handler back to the instruction which triggered the fault (I am trying something hacky that properly resolves the cause of the fault inside the handler so going back to the or...
Hello. The microcontroler used is the STM32F429.There is an 65MHz capable ADC connected to GPIOA pins 0 to 11.Also there is a SDRAM IS42S16400J connected on FMC, that is configured like this :/* FMC Configuration -------------------------------------...
So, I need to implement SMPS for more efficient power use on my STM32L452 MCU. From what i understand, the clock needs to be brought down to 24 MHz prior to any SMPS actions. I am operating the system at 80 MHz, so I need to bring it down to 24 and ...
I have problems when I read continuously the RTC time in stm32f446 at 180MHz, after some readings, this gives me the same value. To find a solution, I implement a delay of 1 second to read the RTC and this solves the problem, however, I don't know wh...
We use some STM32F765GT6 on a project that will be duplicated in a small series (100) and we wonder about its obsolescence perspectives.Do you have any schedule about this component?
My goal is to wake up an MCU that remains in STOP2 Mode. For this i've sucessfully implemented LPTIM to wake-up from STOP2. Now my problem is, that the LPTIM can only be set to a maximum value of 0xFFFF, which is 2 Seconds if i got the stm32 document...
Hello, working with STM32H742, I need 480 MHz in some parts of my code while on the other hand I need to save energy. That's why I came to think about changing D1CPRE and HPRE between (1, 8) and (8, 1) to (maximize , lower) sysclk while keeping the ...
I know how to write to notification attribute (with aci_gatt_update_char_value).How do I response to READ attribute?Thanks,Lior Malik
