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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hello,currently I'm transferring from a Nucleo to the target electronics(STM32G474RE3), but when I download the Code(verified successfully) and start it, the Processor is hanging when the Timer IRQ for the Debugger is enabled.Supply Voltage is ok, 3....
HI,i am using STM32F411 for a digital signal processing intensive application where the ADC is used for continuous acquisition at 1.6MSPS (via DMA), the firmware was developped on STM32L476 for convenience but the final version uses STM32F411CEU6 bec...
Schrodinger's Memory: In debug my STM32F407VG Discovery code is seeing zeros in an array loaded using DMA (which is working), but if I break and single step, the code suddenly see's the values. Super weird! I´m using STM32CubeIDE which was fully upda...
Hello,I am using STM32L011G4U7 and wants to get the adc value where it showed once and not it is giving 0 for the adc raw values. Also please let me know that in order to read the vcc that is 3.3 volts do I need to select VREFINT channel as well alon...
Edit: I've pretty much solved my problem. The issue of course was that I was setting the Complete flag in the first cycle. By changing: if(DAC_Complete){ swap_buffer(); DAC_Complete=0; }to:DAC_Complete=0; while(DAC_Complete){ swap_buffer(); }Things a...
I'm using an STM32F429. I have setup a timer to capture rising edges on CH1 and a DMA to store the captured values into a circular buffer.How can I temporarily stop the DMA from placing new values into the buffer while I'm reading values from the buf...

Hi, I used to write bytes at 0 in flash bytes that are erased (0xFF) but this is no more possible in the flash of the STM32U585 because of ECC that protects 16 bytes chunks I suppose.However now I have an 8K sector programmed with some data except f...

Hello,I think that I found an issue in the HAL code generated by CubeMx 6.6.1 with STM32L4.I2C HAL in file stm32l4xx_hal_i2c.c line 6855 there is an infinite loop : while (__HAL_I2C_GET_FLAG(hi2c, I2C_FLAG_STOPF) == RESET) { /* Check for...
