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 = ...
Hello,As mentioned in Errata sheet of STM32L4xxx, the auto polling mode is not functional. This mode allows an automatic polling fully managed by hardware on the memory status register. The workout in the Errata sheet is to use memory-mapped mode, bu...
