Hi all,I’m working on a project using an STM32F407 and running into issues with low-power modes. I can put the MCU into STOP mode successfully, but when I try to wake it up with an external interrupt (EXTI line on a GPIO pin), nothing happens. The de...
It seems like the program is getting stuck in the Error_Handler loop and not coming out. Could there be a problem with my code? /* USER CODE BEGIN Header */ /** ****************************************************************************** * @fil...
I have a question, when I jump from the bootloader to application code from internal flash, I didn't have to disable the interrupt and re-enable them in application, however when I do using the external flash I have first disable then re-enable the i...
Hello, I found in the documentation search for STM32U5G9 that some interfaces available for high-speed communication, such as OctoSPI and HexaSPI, do not seem to support slave mode. The device we are making requires two STM32U5G9 chips, each connecte...
Hello, I am working with the STM32H747I microcontroller and using the SPI6 peripheral to interface with an external ADC (MCP3462RT). I have observed that when the system clock (SYSCLK) is set to 120 MHz, SPI6 communication works correctly and the ADC...
Hi, When I clear the EXTSEL bits in the ADC1 CFGR1 register, my resolution bits also get cleared ?. My ADC randomly changes resolution. Below is screenshots of the code. Why does this happen ?, I can disable the ADC to write the RES bits to what th...
Hi,We've successfully implemented the use of external RAM connected via the OCTOSPI1 interface on the B-U585I-IOT02A board, using the example code provided in the CubeMX packages for read/write operations. Everything works as expected under normal co...
hi:I have two NUCLEO-H563ZI EVB boards and tried to implement I3C controller and target feature.When ENTDAA was issued, I obtained the target 48-bit provisioned ID "0x020813810100" from waveform, I saw the description from I3C register I3C_EPIDR ,i...
Hi, @FBL I am also using this board and STM32Cube_FW_U5_V1.8.0 to create a USBX stand-alone (without THREADX) MSC device,but struggling to get the board to enumerate with the PC.I'm not sure if it's a configuration issue or a code modification probl...
Hi all, i am going through deeper configuration of GPDMA on STM32U5 and there are some things i do not understand.S/DBL_1 in TR1 register is able to vrite destination/source burst length in range 0-63 but FIFO size is 8 bytes for channels 0-11 and 32...
