Sampling frequency for STM32L476RG in dual regular simultaneous mode?
I have set the ADC clock frequency to 80 MHz and I am operating the ADC1 and ADC2 in dual regular simultaneous mode where sampling cycles I have set to 2.5cycles each, so what will be the sampling frequency for the signal?
NUCLEO-H723ZG web server with external memory
heyI work with NUCLEO-H723ZG,STM32 Nucleo-144 development board with STM32H723ZG MCU.I try to implement web-server on my board.I work with the example of LwIP_HTTP_Server_Netconn_RTOS.From my test, the size of the website will be larger than 600MB. T...
STM32 metrology driver, HAL returning negative values. QE is questioning why negative values, feels this must be HW or FW bug.
Some of the parameters which can return negative values (not all the time, sometimes positive) are: Power Factor, ReactivePowerReceived, ApparentPowerDelivered, and whatever these parameters are:Vmom = -162 AEload = -0.174030 Imom = -43 PF = -0....
Figure 27 in the STM32F446 data sheet wrong - Anyone knows what is correct?
Hi everybody,I want to compensate the internal RC oscillator drift in a STM32F446RCT6. My idea is to measure the internal temperature and the trim the RC oscillator according to this using the designated register for it. Unfortunately the diagram of ...
Resolved! Hello ST community, I am a new member! I would like to ask how does the PWM generation in advanced timers work.
In my case I configured my counter as center aligned mode and my PWM mode as PWM mode 1.Finally I used the CCR(compare capture register) but i don't have no idea how this CCR work that means it sends a PWM signal every period of time or point by poin...
Problem with timer interrupt
I am using HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) to generate a sine wave based on DDS and I have also implemented ADC to get the value and perform some calculation. My sampling rate is 100KHz so my timer interrupt should trigger ever...
Resolved! Is it possible to use the system bootloader via UART as half duplex (RS485)?
I have a STM32H7 connected to a STM32L1 via RS485. I would like to use the H7 to reprogram the L1 using the system bootloader.Has the USART to be full duplex?Thank you, regards
Resolved! AN2598 smartcard interface example code
Hello,I am looking at the smartcard example application - https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Examples/SMARTCARD/SMARTCARD_T0_MFXIn the project .ioc file, I see that the Baud Rate is set to 10752 Bit...
Resolved! debug when using visual com port
Hi,My application will use intensively use Virtual Com Port to exchange datas from my board to the PC. I would like to make sure that debugging through STLink is still possible as i will be exchanging datas. Does St Link use the same USB port for deb...
