Hi,I implemented a UART communication using the DMA feature on a STM32L4 microcontroller.DMA RxCallback is called on UART Idle line detection interrupt as I d'ont know the length of the incomming frame. The baudrate is 230400 and I receive a frame e...
Pleaese give me some idea for this control theory. The output pin should be PWM_A/_B/_C and RESET_A/_B/_C as shown on picture. If I give specific duty cycle and frequency, how to implement it ?
Hi all, I hope someone could help me on this.I have a trouble on read out ADC from a signal 1Mhz, and my current MCU can't read ADC with this high frequency signal. So I decide to use external ADC IC. I found some from Analog device which can support...
I am working with the STM32F4 and STM32F7 microcontroller families. I am sure that I, at some point, have seen a drawing that shows how the different clocks are routed to different peripherals. This drawing was very helpful when I had questions lik...
My product has a 5% chance of that LSI didn't start when system Power up. So IWDG not functional due to LSI missed.Here is my code to start LSI******************************LSI_CNT = 0; RCC_LSICmd(ENABLE); while( RCC_GetFlagStatus(RCC_FLAG_LSIRDY) =...
Hello I am trying to read the Quadrature optical encoder using TIM2 with STM32F103. I've done the Timer settings. But the TIM2->CNT Always zero. I measured the Timer channels with the oscilloscope. The encoder signals reach TIM_CH1 and TIM_CH2.(PA0, ...
I've been working on debugging a hard fault occuring on an STM32F4-discovery board. For context, I'm working with a custom USB library which is used to communicate with an Android device in Accessory mode (this code uses usbh_core, etc and is similar...
We are trying to implement RTC on STM32F103C8T6 bluepill using arduino IDE while implementing this we are not able to do the calibration of the RTC on STM32F103C8T6blue bill using Arduino IDE, can anyone suggest a possible solution for this problem.
