We are working on a bare-metal application using USBX on an STM32N657X0H3Q device.In CubeMX, we configured USB1_OTG_HS under Connectivity and enabled USBX in Middleware. However, when we execute the following function: static void MX_USB1_OTG_HS_P...
Hi,We have a weired problem with a custom N657 design.When using the Nucleo board, its possible to flash the program on the external flash, as long as BOOT1=1.The programmer resets the board and it flashes the firmware normally every time.On our boar...
Heyho,do all SAIs in all MCUs offer the SPDIF output feature?CubeMx and online MCU selectors do not show this info, no time to check 20 more datasheets.For the few STM32 I know and worked or played with (G4, F7, H7) the answer is yes.Merci!
I am currently using STM32G0B1. I found that when using an active crystal oscillator, the STM32 fails to recognize my crystal oscillator, resulting in the HSERDY bit not being set.This is the configuration of my cubemx.Use an oscilloscope to check if...
Hello,I’m currently testing the CSI–DCMIPP interface on the Nucleo-N6 board. I’m following various examples, but the variable used in DCMIPP_Start (lcd_bg_buffer) is not receiving any data. Is there something I might have configured incorrectly?At th...
Hi,I’m working with the STM32F407VGTX and I am using GPIO PA4 as the SPI chip-select (CS) pin. In my GPIO initialization, I set the PUPDR register to configure PA4 with a pull-up, expecting the CS pin to remain HIGH when idle. However, I observe on m...
I turned off all the other configuration aka Alternate Functions..only enabled GPIO PA5 as output Pushpull mode, low freq.its doesnt turn on or off individually..tried to turn on and off using HAL as well as direct registers..both work only when PA4 ...
Hello,In one of our new PCBs we use a STM32L476VET6. For the RTC we use an external Oscillator (shown in the Picture)The drive power is set to the highest level.In our setup, the RTC only works at room temperature and with no probe connected. As soon...
Hi, I am trying to reset HRTIM on an external event using TIM1 TRGO as a reset event. I am trying to make a single pulse every 200ms (5Hz) because I want to make a single puls test. However, I also need a high resolution so I can vary the on time and...
Hi, I bought 50pcs STM32L151C8T6A from one Chinese online vendor, which has device marking with QR code.I encountered an issue while using the new version chip, after initial power-on, the overall sleep current of the product is approximately 5uA(STM...
