About communicate between STM32F4xx and modbus RTU ( hmi weintek )

I have some problem about this issue, i try a lot of to fix it, but it can not run like i expected.If all words i post make anybody difficulty understand , i so sorry a lot.My problem is:Fisrt , i enable interrupt USART_IT_RXNE,Second, in my ISR, i c...

F429: is DMA burst length of 2 possible?

I have an application, which uses 2 channels of TIM1 to drive a full bridge d-class power stage in order to generate a sinusoidal signal. FSW is 200kHz. The CCR1 and CCR2 registers of TIM1 have to be updated at sampling frequency, so I am using TIM8 ...

How to perform the FFT of a signal using the STM32F7 Discovery board

Hi, apologies for the slightly long post, I'm hoping someone could hopefully point me in the right direction here. I'm trying to perform the FFT of a 100Khz signal using the STM32 Discovery board but I'm relatively new to the STM32 DSP in general. I...

Input Capture Mode- STM32 MAT Target

Hello everybody,I want to measure   the duty Cycle of a PWM Signal in Simulink. . I have managed it to  generate a  PWM signal with Simulink and STM32 MAT-Target. The problem is  now when build  a simple model to generate the code, the lines between ...

is the N version available so STM32F745N BGA216 pin 0.8mm pitch??

its in the datasheet but cant find it anywere

An4013 "STM32 cross-series timer overview" possible errors

Hello,I think following things in 2.4 Timer output compare mode are wrong:3d) Enable the capture / compare output by writing CCxE in CCMRx register.should read Enable the capture / compare output by writing CCxE in CCERx register.and CCx update rate ...

Hi all, I want to read data from several sensors using 1-Wire and I2C. Would it be better to connect all sensors with a similar protocol to one pin or use if possible different pins for each sensor. What are pros and cons for each solution?
