According to some reference it is good to have ground polygon under IC 1. Is it okay to have ground polygon under IC? 2. Does it effects heating issue?3. I saw two hole behind the IC of nucleo 144 board. What that mean?
On my current board the STM32G030 is getting very hot. I have even tried a board with no connections to the processor and all pins set to analog. I have checked the power supply and it's 3.3V. The board runs OK but I am worried about the processor...
Hi all, I’m working on enabling USB High‑Speed (HS) communication on an STM32F446RE using an external USB3300 ULPI PHY, but I’m running into several issues and can’t get ULPI communication working. Current Issues: DIR pin stays high – it appears the ...
We are working with the STM32 Nucleo-G474RE board and using two quadrature encoders—NEMA 23 and NEMA 34—connected through AM26LS32 line receivers to TIM2 and TIM3 respectively, configured in encoder mode. In our project, we initialized TIM2 and TIM3 ...
Hi team, I am working on stm32F7 discovery board, I am working on USB MSC Device however i am not getting , how to configure external flash of this discovery board as Mass Storage. My main goal here is as soon as i connect the controller t...
Hi all, I have a custom board and application using the mentioned MCU, when I use the "run" with the Release option on STM32CubeIDE and once I use the board alone the FW starts flawless as soon I power up. Now when I use the STM32CumeProgrammer to u...
Hello,I am working with an STM32G431K8T6and using the LL library to configure SPI in master mode.The issue is with the MISO pin (PB4).The pin is configured as SPI input, with no pull-up or pull-down.When PB4 is left unconnected, the voltage is measur...
Hi, I have been trying to implement a logic to flash the updated firmware on top of existing with established DFU mode and using stm32cubeprogrammer. Where I chosen bin file for flashing and I provided the starting address as well. For confirming I h...
I'm using STM32F429I-DISCO with external SDRAM and DMA2D to render graphics.CPU run at 180 MhzSdram 90mhzLtdc clock: 3mhzLcd : 240*320 color RGB565Issue:I use DMA2D to fill the screen, then on Transfer Complete interrupt, I trigger a second DMA2D to ...
Hi,I have a question regarding the backup SRAM in the STM32U5. The reference manual is not clear about this:On the one had, it mentions the following Which seems to indicate that it is possible to place the device in standby without powering SRAM2. H...
