I want to minimize LCD current consumption.LCD current consumption is too high.After updating the LCD status, we immediately enter STOP_MODE to save current. (Keep repeating this)I would like to reduce the LCD's current consumption by reducing the LC...
I'm drawing schematic for a small project, I have an information trouble with SDIO. I don't know how to wiring SDIO interface to micro sd card slot. Is there any document can help ?Thank !Sorry if my English is poor.
I use STM32 Nucleo 411RE, it's connected to esp8266 via UART in DMA mode, after power on, DMA had status "HAL_DMA_STATE_READY" and program doesn't call "HAL_UARTEx_RxEventCallback". I discovered that if I hold RESET button, DMA status changes into "H...
Hi, I have created this kernel for an ARM Cortex M3, on an Atmel (microchip) board, and now I am porting it to Nucleo f767zi.I thought it would be an easier task, just adapting the HAL calls, and kernel (C and ASM) routines would keep the same. But I...
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...
