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...
Hi all! I am new on STM32 this is my first project on STM32CubeIDE. I want to generate variable duty cycle using ADC with complementary PWM. When I did the code for one channel PWM it works well and the duty cycle varies but when I did it for the co...
I use a board with STM32F405 + W25Qxx. At the moment, I have implemented downloading the firmware file to an external flash memory (via CAN). The process of downloading and verification is implemented in the main firmware. It is necessary to implemen...
Please see this thread from 2018 https://community.st.com/t5/stm32-mcus-products/stm32f4-hsi-accuracy-drift/td-p/360021 The poster complains that the datasheet claims 1% accuracy for the RC oscillator over full temperature range, but other sources (s...
Hello,Thank you in advance for your assistance.I have designed a circuit with STM32F446. I am using an external 25MHz crystal. The main application program runs fine without any issues, and USB communication works. However, on some boards, I am unabl...
At present, when STM32L412 uses the HAL_SPI command to read back the Register, no matter which Register is used, it is 0, but it is normal to use LA to read the data. The waveform is as follows:Is there any unprocessed program that causes the SPI rea...
In the past, we've discussed the fact that in STM32 TIM, there's a delay between Capture and Reset through the derived from the same signal than the Capture. This delay causes period measured using the method called "PWM Input" in RM, to be a couple ...
I have tried setup STM32G071 Sink port and connected with Apple 140w. I want to request 140W but it's seem STM32 not yet supported EPR mode in PD core. Do you have any examples for EPR in STM32?
Posted on March 12, 2015 at 14:34I have problems with my IAR and ST-LINK debugger tool. As soon as I start the debugger, the SPI clock (STM32F103R8 SPI1 at PB3) stops. I use the ST-LINK over SWD. What could I have done wrong? #spi-st-link
Hello all, I'm working on a custom PCB using the L072RZT6. I want to convert pins PB6 & PB7 from an I2C assignment to GPIO_EXTI during run time. Is that possible with HAL_I2C_DeInit?Currently, the board goes through the pre-generated startup process ...
Hello everybody,i am having trouble determining the wakeup source after power cycling and i can not figure out why this is.Simple test case:I am using the NUCLEO-L496ZG->Examples->PWR->PWR_SHUTDOWN example as a base.The example was slightly modified ...
