Resolved! How to setup SPI DMA on the M4 core for the STM32H745 chip
I have a hobby project where I'm looking to design a flight controller using the STM32H745 microcontroller. My plan is to use the M4 core for data acquisition while using the M7 for the flight control stuff. I have a custom PCB with sensors connecte...
Resolved! Issue with memory allocation updating on its own.
Hi I am using Atolic TrueStudio and have some global variables. For some reason one variable is simply updating every time I step through the code with the debugger. I am using a STM32L433 processor and have 56k ram free. The variable is a character...
I have a project using stm32f765,now i want to migrate to stm32H743.I want to know if i can use the code that has been written for stm32f765 instead of writing a new one, If yes , is it enough to only change the header files name?
Hi community. I mean for example are some changes necessary in some HAL or LL APIs for different peripherals or i should leave it as the way they were written in pervious code(Code for stm32F765) ?
D flip-flop
Hi,I need to normalize the asynchronous transmission to a specific baudrate in real time. I know flip-flop D is fine, but I don't want to add extra elements to the layout. Can I do it with timers or maybe some other solution?
STM32F429 Sleep mode and Systick
Hi'I'm using an STM32F429 in a project that needs to enter to sleep mode.I can't determine if I need to disable manually the HAL tick previously to entering in sleep mode, or if the sleep mode enter instruction does it by itself. Can anyone tell me?T...
How do you set the output pin low after timer's one time pulse?
I have timer8's one-time-pulse working however when the CNT reaches ARR and is set back to 0, the output pin goes high again. ( since CNT < CCR1 )How do I ensure the output pins remains low after the one time pulse?
STM32F030F4P6
When I am uploading a program via Arduino IDE, it is giving me an error as " arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: region `FLASH' overflowed by 18724 bytes"and " exit status 1Error compiling for board Generic STM32F0 series."Pleas...
Resolved! STM32H745: VMA does not match actual memory address for a given variable
In my application I am using initialized data in shared memory for the use in a user interface. The memory is in the SRAM2 at 0x30020000. Both cores need to access that same data.This code is placed in the Common directory so that it is picked up dur...
