STM32L496 - Power OFF SRAM1 during Run Mode

I want to know if is possible power OFF the SRAM1 (256kb) and keep only SRAM2 (64kb) ON, during Run Mode. I know that is possible power OFF SRAM2 in Standby-Mode with the register PWR_CR3 (bit RRS). - Reference Manual pag. 187

I want to FDCAN LOOPBACK using STM32G474RE.

I want to FDCAN LOOPBACK using STM32G474RE. but i'm not find example. help me please. I don't have much time left. :(

I would like to transmit few values from STM32F303 to STM32F407 through CAN. But the CAN enters into sleep mode after few transmissions. Tried to use HAL_CAN_WakeUp(&hcan) function but in vain . Any leads would be appreciated.

Can the STM32L4+ RTC use an external LSE clock when in VBAT mode?

I couldn't find this mentioned in another thread, most discussion was based around LSE vs HSE & LSI. Basically, I'm wondering if we used an external 32.768 kHz clock with the STM setup in bypass mode, whether that clock could be used to maintain RTC ...

Receive SPI data from an unknown device.

Hi I want to communicate with a device that uses SPI, I want to grab data from this device but when it transmits a byte waits for an acknowledgment signal which is a positive pulse with 2us lent. So I should wait until it sends 1 byte of data, store ...

Trying to get CAN2 working.

I'm using the STM32F105R8T6, STM32Cube_FW_F1_V1.8.0, and Atollic TrueSTUDIO 9.3.0.I have CAN1 working already, and am now trying to get CAN2 working *instead*. That is, I'm swapping over from CAN1-only to CAN2-only, as an interim step before trying ...

Modify ACK bit in CAN normal mode STM32F4

i want to build a node that can receive and send can frame without sending out the ACK bit. Like the silent mode but i want to be able to transmit too. There is a way to accomplish that?

Can ST8500 MCU support communication through DC lines? The Voltage of the DC lines will be around 5-20V.

STM32 wakeup from gpio using radio rx done interrupt

I want to wake my STM32 mcu from stop2 mode using an external interrupt from sx1262 radio. I configured the gpio pin like this:/*Configure GPIO pin : RADIO_DIO1_Pin */ GPIO_InitStruct.Pin = RADIO_DIO1_Pin; GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;...

STM32L476 ADC w/ DMA not stopped after end of sequence

Hello,My question is related to "STM32L4 ADC w/ DMA overrun error" which was closed unanswered.I am implementing an algorithm that uses ADC with DMA on a NUCLEO-L476RG.The ADC is configured as follows:Clock Prescaler: SynchronuousDMA Continuous Reque...
