Which Xferoption should be selected and should we use both functions ieHAL_StatusTypeDef HAL_SMBUS_Master_Transmit_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t XferOptions)andHAL_StatusTypeDef HAL_SMBUS...
i replaced board mcu from stm32f103c8t6 to stm32l412cbt6.now i cant connect board with swd port.is stm32l412 not support swd port by default?or do i need to change some schemetic for stm32l412?
Hi All,I am trying to generate required no of pulses using PWM. This is to implement to control stepper motor with position control. I use HAL_TIM_PWM_Start_IT to start pulsing and count the no of pulses in HAL_TIM_PWM_PulseFinishedCallback. I notice...
Hey folks!Got some questions around synced timers on STM32F401, where the aim is to have two timers start together, where one timer has a period an integer multiple of the other. I've got what I need working but how it works, doesn't add up.Here's th...
Hello everyone,I'm just starting to learn assembly for the ARM architecture. I'm also in general a beginner with the assembly language I have just some minor experience with the x86 assembly but that's about it.I'm following a course on Udemy and I h...
Hi,I have a custom board with an STM32G474RE. I use 3 CANs with 3 independent CAN tranciever on the board. I tried sendind CAN message from CAN1 to CAN3 but the message is not received. At least the callback funnction is not called. I used an oscillo...
I want to print out 5 waveforms during 1us.So, I printed out 5 MHz period PWM from TIM3.We tried to change the duty cycle of TIM3 to zero at interrupt time by running a 1 MHz timer counter on TIM6. However, it was confirmed that TIM6's 1 MHz timer co...
I think the article here:https://community.st.com/s/article/FAQ-DMA-is-not-working-on-STM32H7-devicesis wrong. In solution 3 it invalidate D-cache before reception. This doesn't make sense, it has to invalidate the D-cache after reception.
Hi,I have a custom board with STM32L010. I used STM32 cubeMX to initialize the GPIO,I2C,SPI,ADC,USART,LPTIM2,CRC,DMA and RTC. Then I de-initialize everything except GPIO and put the controller in sleep mode. The current consumption still is 250 uA af...
I'm using this code to read from a flash chip with quad SPI: // send read command and read page data OSPI_RegularCmdTypeDef sCommand; memset(&sCommand, 0, sizeof(sCommand)); sCommand.OperationType = HAL_OSPI_OPTYPE_COMMON_CFG; sCommand.FlashId = ...
