hi everyone.I'm trying to index different GPIO ports and pins. #define STEP1_HALF1_PORT GPIOA#define STEP2_HALF1_PORT GPIOB#define STEP3_HALF1_PORT GPIOA#define STEP4_HALF1_PORT GPIOC#define STEP5_HALF1_PORT GPIOBGPIO_TypeDef *Half1StepPortNum[5] = ...
Dear STM CommunityIn order to ease our debugging, I would like to make use of the Micro Trace Buffer which seems to be integrated in the Cortex M33 Core (e.g. stated by STM here: https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-co...
Hi,My MCU us stm32f401rct6.This MCU has three UART and all UART are using for service. No console UART port :(So, I make a USB CDC device to use console port.But, iwdg is not working. When I use UART console port, while(1); occur watchdog reset. But,...
I have SPI1 setup as Receive Only Slave with DMA enabled. I send 10 bytes from SPI2 ( to simulate a full duplex master uC ) and it works well the first time I transmit 10 bytes. When I transmit 10 bytes a second time, SPI1's overflow flag gets set...
Hi,I'm currently trying to understand the recommended MPU config (when settings up an 8 bit LCD connected via the FMC on an STM32H742. Everything is currently working, but I haven't been able to wrap my head around why configuring the MPU regions wit...
Hi everyone.I am recently working on stm32 chip and found a page show the power consumptionseems GPIO port C and F can save half the power than A and Bshould i always consider to use gpio port C and F ?or the consumption is too little that we don't n...
Posted on October 11, 2016 at 08:27Since the programmers are supposed to munge main.c into their own project, Cube generated code being just a starting point, why would ST put in a copyright notice that takes ownership of the code?This is the transi...
Dear communityI have a strange behaviour, when I want to read the flash of an STM32U5A9 in a FreeRTOS task. I have a function, that programs incrementing numbers on a whole flash page of 8 KB (confirmed with J-Mem, that programming worked). If I want...
Hello,As I understand from datasheet if you use 64, 81, 100, 132 or 144 pin package there is separated power supply domain for USB transceivers, i.e. VDDUSB which should be connected between 3.0-3.6V or connected to VDD if USB is not used.However, 48...
Hi, i'm trying to test the Eval STM32F769i-Disco with the B-LCDAD-HDMI1 Adapter.Is there anywhere a running Software to test this Hardware?Thanks DT24
