Hi ,I'm working on the STM32H7S7L8-DK and i would like to know if it is possible to use both USB_FS and USB_HS as two separate Virtual-port-com Device mode When I try to do it for one it is impossible in cube MX to do it for the other.Thanks !
Hi everyone,I have a question regarding the compatibility between I3C and I2C devices on the STM32H533RETx.I’m using the I3C2 interface on my MCU:PC6: I3C2_SCLPC7: I3C2_SDAOn this bus, I have only one device connected – an I2C EEPROM (M24C32-RMN6TP)....
Hi all,i see H7 supports clause 45 MDIO access, but in the HAL library looks not implemented, i see only clause 22.How should i proceed to read/write c45 ? Thanks,angelo
Hi ST team,I'm using STM32H743IIT6 with REV_ID=0x2003 and encountered a problem. Quadspi dual-flash indirect read mode is used for continuous reading data from external. According to RM0433, If QUADSPI_DLR = 0xFFFF_FFFF and FSIZE = 0x1F (max value in...
Hello:I think I have found how to enable the i-cache on the STM32N657X0 using the STM Cube IDE through using the Pinout & Configuration of the project. Two questions:1. Is the icache actually enabled, or did I just made it available to be programmed?...
Hi,I'm encountering an issue with OCTOSPI auto-polling on the STM32U5G9NJ-DK1 Discovery Kit while following the "Octo-SPI FLASH in Regular-command protocol example" from AN5050 (Rev 12, February 2025). Specifically, in the OctalPollingWEL() function,...
I have been trying to reduce current consumption in a custom board and have seen that current is not getting below 9mA for microcontroller , i am running system on MSI at 2MHz and ABP and AHB peripherals both are at 2MHz ,and to enter in low power ru...
Hi all,I hope everyone is progressing well with their projects.I'm currently working with the STM32H47 series microcontroller. In my project, I log certain values and store them in external flash memory. Later, I use USB host functionality to retriev...
Hello, We are currently experiencing an issue with the STM32U585QII3 microcontroller. We use the LSE pin of the microcontroller to inject a 32.768 kHz signal generated by an external TCXO MEMS-type oscillator, with the input configured in RCC_LSE_BYP...
Hello,I am using a STM32H757 to convert 12 analog channels using ADC2 and ADC3 (code running @ Cortex M7).- Both ADC are configured at 42MHz sync clock, triggered by a timer- ADC2 use DMA1s0 to transfert data to AXI SRAM.- ADC3 use DMA1s1 to transfer...
