STM32L4 STOP2Mode

I'm using STM32L476VG and STM32Cube FW_L4 V1.17.1 version HAL Function.I thought STOP2Mode and RESUME work fine.However, when I took the current consumption waveform, it is the same as STOP1Mode.Why is this happening?void Sleep(void) { MX_UART4...

we are implementing the Android open Accessory on stm32f429 how will we implemnt ? please help me

actually we got two source code of AOA protocol dedicated to stm32f429 and stm32f407 board but we want to implment AOA protocol in latest hal library . for that i want some helpold source code link belowhttps://github.com/YuuichiAkagawa/STM32F4_ADK i...

STM32H723ZG Board losing communication

Hi all,Nucleo-144 Stm32h723zg board while debugging suddenly loses communication and shows target not found, unable to read register values. This does not happen always but during debugging this issue is coming up,any solution or any problem with the...

[Help] Custom Board STM32H7 programming external memory MX25LM51245G via UART

Hello,I am working on a STM32H7 device that needs to be able to program external memory MX25LM51245G using UART instead of STLink. Is there any bootloader available to handle this? Or, what is the best way to tackle this issue? Thanks.

STM32F4 Timer Triggered DMA SPI – automatic NSS > problem - workaround?

STM32F4 Timer Triggered DMA SPI – NSS ProblemI have a STM32F417IG microcontroller an external 16bit-DAC (TI DAC81404) that is supposed to generate a Signal with a sampling rate of 32kHz. The communication via SPI should not involve any CPU resources....

I am interested in STM32U5 because of CORDIC as I do have trigonometrically intense applications. Apparently DSP with hardware multiply is superior, and is also provided in the STM32U5. Respectfully, why include CORDIC when DSP is also available?

STM32F303VC SPI Communication: SPI2 (Slave) SPI1 (Master)

Is it possible to send data from SPI2 to SPI1 ? SPI2 being the slave. In SPI, Master initiates the communication, correct ?This is how i do it:When the Slave SPI2 receives a byte from SPI1, i set a flag, and i check for this flag in main context.If t...

STM32F411 specs for ADC are 2.4 MSPS. my waveform generator set at 500 KHz captures 12 values from peak to peak, indicating 6 MSPS. Using DMA, no repeat values to indicate it is re-reading the adc_dr . ???

STM32L0x1, trying to get UART2 interrupts working. UART2 on PA2/3 is selected Tx interrupt is working, Rx is not, intermittent results. Modes: Microprocessor Communication and Asynchronous act the same. Details below.

Intermittent results during a loopback (same processor, Tx to Rx) test. Happens the same on both STM32L041G6 and STM32L051K8U6 processors.STM32CubeIDE (recent version) used to enable Uart2, Interrupt enabled, no DMA, 9600 baud, 8bit, 1 stop, no pari...

DAC TEN and SWTRIG

Hi everyone, I'm experimenting the DAC features with my STM32F303RE and I have a dubt. .RM says: "If the software trigger is selected, the conversion starts once the SWTRIG bit is set".Now, if I only set the DAC_DHRx and the EN bit, the DAC works pro...
