I'm using a STM32U585 that has some hyperRAM attached to OSPI2. I've memory mapped it and it's working well during normal operation. I've noticed, though, that when I leave it powered and put the processor into Stop 2 mode, it corrupts some of the ...
I would like to know the lower limit of the voltage at which the ADC can maintain accuracy, but I don't know the next mode.What are the degradation modes of VREFBUF characteristics in the STM32G031x4/x6/x8 data sheet?Also, what are the conditions for...
In UM3115 STM32H5 Nucleo-144 board (MB1404) rev 2 - August 2023, page 29, table 19 listing CN13 pinout, A7 D- USB_FS_N STM32H5 Pin is typed as PB11. I guess it is a typo, it should be PA11. In the same table, B7 D- USB_FS_N is correctly typed as PA11...
Hello,I'm just started using a nucleo-h743x. I have configured the I2S to acquire some audio from the a digital microphone.Supposing that I use one of SPI1,2,3 for that, the i2s clock reaching the peripheral should the one that in MX is called (To SP...
I've implemented STOP 1 mode on STM32L476 using HAL function. The current consumption is >1mA even in STOP mode while I've disabled all the clocks. I'm unable to understand this.
Hello everyone, I'm trying to set all the pins(except 11) of port F of STM32L476 as Analog to save power. for(uint8_t GPIO_PIN = 0; GPIO_PIN < 16; GPIO_PIN++) { if(GPIO_PIN != 11) GPIOF->MODER |= (3 << (GPIO_PIN * 2)); } But it resets my progr...
I am trying to use the usb COMPOSITE library. (AL94.I-Cube-USBD-COMPOSITE.1.0.3)Followed the instruction How to generate the code from MXcude for USB CDC and USB HID.the code compile successfully. and I can see those devices when I attach my NUCLEO b...
Hi All,I am looking to use the I2C3 for connecting to an OLED display. I have already used I2C1, and due to design requirements, I cannot use the same bus to communicate to the OLED display, and hence I2C3 is my only option. I2C3_SDA is an alternate ...
Hi there,Looking into the TRM for the STM32L412xx board, I was wondering if I could use a DMA to copy constant data from the Flash to SRAM. The system architecture block diagram connects the DMAs to Flash through the DCode path:However, while reading...
Dear allSituation 1:I use Nucleo-F413ZH with AMC1306EVM (PA8 DFSDM_CKOUT, PB1 DFSDM1_DATIN0)Result: DFSDM is working fine with DMA. In this situation I use mode PDM/SPI input from CH0 and internal clock.See code details in files with ending dfsdm_clk...
