Posted on March 23, 2017 at 16:44Hi! I've just recently checked http://www.st.com/content/ccc/resource/technical/document/application_note/b9/9b/16/3a/12/1e/40/0c/CD00167594.pdf/files/CD00167594.pdf/jcr:content/translations/en.CD00167594.pdf that is...
Posted on March 26, 2017 at 18:55 I use SPI and DMA transfer. I use the following functions: HAL_StatusTypeDef HAL_SPI_Transmit_DMA(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size); HAL_StatusTypeDef HAL_SPI_Receive_DMA(SPI_HandleT...
Posted on March 22, 2017 at 13:14Is it possible to use DFUSE to update via USB if I have an external phy? I'm using an STM32F777. I do have a 25 MHz external crystal for HSE.
Posted on March 23, 2017 at 13:47I am using TIM2.CH2 input compare. No other interrupts are activated except TIM2.CH2. In TIM2_IRQ handler all IC bits except CH2 are set. Why?Using STM32Discovery on IAR. I expect TIM2_IRQ to fire up on trigger from ...
Posted on March 14, 2017 at 17:04Hello everyone!I was forced to move my project to HAL Libs for bunch of reasons beyond the scope of this discussion, and ever since, I ran into problems getting the SPI to work properly. I spent a tremendous time try...
Posted on March 25, 2017 at 09:27Hello everyone. I am using STM32F401RE Nucleo Board. I want to communicate with PC through USB CDC Virtual COM Port. I was following an instruction for STM32F4 Discovery and then I realized that my Nucleo Board didn'...
Posted on March 23, 2017 at 20:24STM32F437 processorI have no experience using the stm32 timers with DMA so I wish to solicit suggestions before banging my head against the wall.I have set up a counter using an ISR to count pulses (RPM) and it works...
Posted on March 24, 2017 at 19:00STM32F437I am using TIM4 channel 1 and would like to have the timer output handled by DMA instead of my timer ISR but my DMA attempt is not working. So I am fishing for timer/dma example code hopefully that uses DMA ...
Posted on April 17, 2015 at 13:06Hey guys, using the STM32F4 + cube, I setup a CAN device which works good until I play around with disconnecting the CAN bus lines and reconnecting them. Doing so produces bus errors and I am not sure how to handle t...
Posted on March 25, 2017 at 06:55I've downloaded STM32 FOC SDK for testing closed lo loop stepper driving.Simply reviewing the API, I am not sure the FOC SDK is useful for closed loop control of stepper drive.For example, the shunt resistor configur...
