I am using STM32F423RHT6 in my project. I am using 2 ADC Channels for measuring Voltage and Current(through Current Sensor). But I am facing a strange issue. Where the channel corresponding to the current is getting accurate values of analog voltage....
Hello,I'm facing a very strange issue with timer PWM in DMA mode.I use the PWM channel to send step pulses to a stepping motor in order to free the mcu while the motor is moving, rather than using time consuming delays.The issue raises when I change ...
Hi,I see from the MX file for the display project for STM32U575ZI-Q with GFX02Z1 display to have following pins assigned. I have question on these pins objective and I have tried to explain my understanding. Please suggest if my understanding is corr...
I’m encountering an issue with my STM32H755 application after moving the flash memory to accommodate SBSFU. The Reset_Handler address in the vector table is misaligned by one flash bank. Here are the details:Background:Microcontroller: STM32H755Bootl...
Hi,My RAM_D1 is almost full, mainly because of LTDC frame buffer, etc., I need to use RAM_D2 and RAM_D3 for my variables, arrays and other staff. I am using RTOS CMSIS v2.There are a few posts about using RAM_D2 and RAM_D3 in H743, in the forum, but ...
Hi allI'm working with an stm32f4 and I have a question about current consumption on stop mode, on the pin PC1 I have a external pull up 10k connected to 3.3v, before stop mode what is the best mode to avoid PC1 consume 0.33ua ? Right now I have put ...
Hello everyone,I'm trying to debug firmware on a custom ST32H750XBH6 board. Once I configured the MCU on StmCubeMX to act as a USB_OTG_HS after flashing the firmware the ST-link stopped working and it gave me the error message:Target no device found:...
Hi , i am using STM32H753z, implementing the SPI. when i using HAL_SPI_TransmitReceive() data is transfer and receive happening but data is mismatching. when i using HAL_SPI_Transmit(), HAL_SPI_Transmit_IT() is showing busy when i debug same wave...
Hello,I am working with the STM32H7S78-DK board, and I have enabled the UART4 serial interface (using PD0/PD1) for both programming and debugging. However, I am unable to print logs to the Putty terminal.Environment:STM32H7S78-DK BoardUART4 on PD0/PD...
I'm trying to get Ethernet working with STM32F765VIH MCU and developing using Keil MicroVision and CubeMX 6.11.1When setting up CubeMX I'm seeing warning message that RAM needs to point to 0x24000000 for ethernet to work.I don't see an option for set...
