hello, i'm using a stm32f4 discovery to control a dc motor, for this i've used different timers for the different actions i have to do in this one, TIM2 is in charge of reading encoder, TIM3 is the pwm generator that goes to a H bridge, TIM4 i use it...
I am using stm32h745zi-q board and I am working on the full duplex SPI. Here I aa using spi1 and spi4 . I used interrupt based at the spi1 means master side and I used DMA for SPI4 means slave side .Here I am able to get the complete data in the SPI1...
Hello,I have to transfer the bytes received from UART2 to the circular buffer via DMA. The microcontroller I am using is STM32L010F4 with LL instead of HAL.When I send a sequence of bytes to UART2 I notice that only the first byte is loaded into the...
I have a interrupt that is generated from a finite state machine on the LSM6DSOX sensor. I have routed the interrupt to the INT1 pin. How can I attach an interrupt handler function to this interrupt so the function is executed whenever the interrupt ...
I am interpreting this to mean that each data signal (including CMD line) should all contain equal number of vias. For example if line D0 is routed to MCU and this trace requires 2 vias on its path to the MCU then all other data signals should also c...
Hello,I have problem with CRS (Clock recovery system) in STM32F091xx. I use HSI48 and I want to generate synchronization with LSE (32.768 kHz).How to set FELIM in CFGR register and TRIM in CR register ?Thank your for help.
Hello everyone. I am using STM32H743IIT with a sensor and two external SRAMs. The sensor is connected to the STM32H743x by SPI5 and EXIT2. The external SRAMs are connected to the STM32H743x by FMC.The sensor triggers the EXIT2 and in the interrupt fu...
I have configured TIMER2 to capture PWM input (Basically PWM inputmode). Both CCR1 and CCR2 captures period and ontime of the PWM signal respectively. I configured DMA to captures these two registers CCR1 and CCR2 by configuring array of two 32bit bu...
HiI created my new project follow SubGHz Phy Ping Pong example project. This is my MX_RTC_Init() function:void MX_RTC_Init(void) { /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateType...
I am working in a new card ETH MAC comunications based design, with a number of digital inputs, a number of digital outputs and a number of ADC channels getting analog inputs from external sensors. The specifications of the hardware design starts wit...
