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...
Posted on March 24, 2017 at 17:46I am developing program for usb communication and i am using 'STM32_USB-FS-Device_Driver' library in atollic true studio.in USB communication when EP2_OUT_Callback is working properly. but during interrupt for EP1_IN...
Posted on March 24, 2017 at 17:44In RM0090 section 18.3.15 Timer synchronization all the master/slave examples use timers 1 and 2. Can only adjacent timers be used in master/slave modes, must the lower number be the master? I don't see where the cou...
Posted on March 24, 2017 at 20:03Hi,The DMA2D peripheral is great, and I'm using with no issues. I was wondering if it's possible to rotate an image 90 degrees using this peripheral. Has anyone done this?Thanks!Bobby
Posted on March 22, 2017 at 22:54I ultimately need 'instant on' ADC conversions. For instance, when a timing gate goes high, I need to start taking ADC values immediately (the signal is only 100us wide), The problem I'm running into is the lag: fi...
