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...
What is the default timer clock frequency of the APBx buses on an STM32F410RB? I've been considering it to be 16MHz to calculate the frequency of my PWM wave, but it turns out I get half the frequency on scope (is the default clock at 8MHz for timers...
On G030 if an overrun occurs on usart2 (no FIFO available) the reception of further bytes stops.Is this intentional or an known error?
Hello, I'm new to STM32, I bought a Nucleo board with a STM32F334R8T6I want to generate a PWM of 10kHz and read some data in ADC channel, unfortunetely, there some conflicts between this two and I can not generate a PWM with more than 5kHz.I need som...
Hi i plan new design and require activate for example on PA3 ADC1_IN4 and same time COMP2_INP.Is this possible and if yes how sequence to setup HAL LL or direct?
I'm a beginner with STM32 and I'm trying to generate a sine waveform using a STM32G4 through the NUCLEO-G431KB board to be exact. I've been looking through tutorials on how to generate a waveform using a STM32G4 board, particularly this tutorial but ...
Hi, I need the project used to generate the external loader: MX25LM51245G_STM32H573I-DK.stldr. My custom board uses a STM32H563VIT6 and the same octo-spi flash from Macronix used in the STM32H573I-DK board. But with different gpios connections. So th...
I have been examining the X-CUBE-EEPRMA1 codebase and noticed a couple of issues with the code that is causing delays in the firmware:m95xx.c. Line 344 "pObj->IO.Delay(6);". Is the 6 ms delay necessary? In line 353, the system checks if the chip is r...
I have an STM32-L4P5DK connected to an external ADC, with SPI2 configured to read ADC samples on every falling edge of the DRDY signal. The DMA1 configuration is as follows:DMA1 CHANNEL1: DMA_GENERATOR0DMA1 CHANNEL2: SPI2_TXDMA1 CHANNEL3: SPI2_RXThe...
... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! Okay, I will probably not use too much HAL, will use Release version with opti...
Hello,I have a rather strange problem on the CM7, where code executes with half or third the speed it should.I have no idea what is causing this, but I know how to fix it: by adding one or several NOPs somewhere in the code.Example: an ISR is taking ...
