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 maximum HCLK of STM32F407 is 168MHz, while the calibration value of Systick is 150MHz HCLK. What is the reason for setting the calibration value of Systick like this? Why not set the calibration value for Systick based on 168MHz HCLK?
Hi, I'm currently using the STM32U575 to develop a product, and my clock configuration is set to the maximum of 160MHz because I'm dealing with a large amount of data. I have two SPI channels collecting data at a sampling rate of 20kHz, with each sam...
Hi,We were using CubeProgrammer on Windows to program our MCU in DFU mode and everything was moving well until we noticed MAC does not detect USB in DFU mode.So, I am wondering if there is something we are missing to do which the MAC operating system...
Hi all, I need to generate a DAC output which is operating on 2 quadrants and the quadrants may be asymmetrical with respect to both the duty cycle and the amplitude. Attached a picture which better explains what I need. MCU STM32F446RE DAC OUT1 on p...
Hello,I have a problem on a STM32H753 which I do not understand.I want to sample some data from ADC with a given time period.So I use the TIM2_TRGO as Event generator for the ADC3 (via EXTSEL)ADC3 is configured in 12 Bit single conversion, in the seq...
Hi，I am using the PWM1 mode of the STM32G031 TIM1 and I noticed that the rising and falling edge time of its PWM output is about 20 ns. I have used the PWM fast mode but this time is not getting shorter. I would like to know if this time is normal? B...
Hello Team,Want to use systick timer for time base of 1uS without interrupt. Please help me on this to configure it without interrupt. Regards,Sachin N
Hello, I am using STM32H7 dual core series. Currently I am planning to enable FreeRTOS in M4 core and let M7 core run in regular fashion. As FreeRTOS uses SysTick, I have given M4 core on of the controller timer. Is there any need to also give M7 cor...
Hi experts,I'm adding to my existing code (that runs on a STM32F105) a function to store a word in the flash.I basically copied the code from the official example based on the HAL libraries, here my function:uint32_t FLASH_Write_Data(uint32_t StartPa...
HI,I would like to use the speaker output on the STM32H563ZIT6. I reviewed the wiki, but there aren't any references about how to play audio with the speaker output. Is it possible to enable this output to play audio?Does the STM32H563ZIT6 have built...
