New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...

Debugging, but not running.

Hey,I build my own STM32 board with the STM32L011G3 and started testing with a simple blinking program via SWD and ST-Link V2.  When I'm debugging it, everything works fine, but when I use the run command in SW4STM32 the LED lights up, but does not t...

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...

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...

Resolved! STM32L152C-DISCO UART doesn't work correctly

I want to send the numbers in order but it only sends the number 0 constantly. When I make the delay 100ms it only sends 0 and 1. When I remove the delay completely, it sends numbers from 1 to 30 in order.

uart communication between stm32 and stm32

HelloI want to use two STM32F407 MCUs to enable bidirectional communication via UART communication with each other.I would like to have a two-way communication that turns on and off each other by installing a switch and an LED, respectively. Thanks a...
