In the FS mode the reference manual state that USB RX DMA is only available in HS mode. In MXCube it seems that I can set USB OTG HS and set internal Phy to "device only". Does this activate the RX DMA? It also seems to change the pins assignment o...
Without Interrupt signal STM32F207 print continuously.How to avoid it...void EXTI9_5_IRQHandler(void){ /* USER CODE BEGIN EXTI9_5_IRQn 0 */ /* USER CODE END EXTI9_5_IRQn 0 */ printf("\n\rInterrupt Occur\n\r"); /* USER CODE BEGIN EXTI9_5_IRQn 1 */ /...
I'm considering to use a STM32l1's family microcontroller at my project, so, as I will need to plug a flash drive at my device, I would like to validate my concept with a evaluation board that can do this. Does my MCU's choice seem right?Does this ev...
I'm trying to use the HAL SPI driver to do a basic loopback test. I fill a buffer with incrementing values, and send that out while receiving into another buffer using HAL_SPI_TransmitReceive. I have 2 separate conditions both of which show odd behav...
Hi, I have a question about connecting Comparator with HRTIM. I am currently working on Buck Converter with Digital Peak Current Mode Control. In this kind of control I need to measure the current of the inductor and compare it with another current w...
Hello all,I've been working on and off with the timers on the STM32F7 and I've noticed a few inconsistencies, though it may well be me not setting something right.I'm using:STM32CubeMX 4.27STM32 WorkbenchFirmware 1.12 for F7STM32F767ZIGetting the tim...
I'm running v1.26.1 of CubeMX and any code that I add between the /* USER CODE BEGIN.. and /* USER CODE END.. comments gets deleted every time I (re)generate the project. I have the 'Keep User Code when re-generating' option ticked. What am I missi...
Hello,I'm working on a product where we will use the STM32L71 device containing an I2C Interface for servicing and control. I develop first parts of the firmware on a STM32L53 nucleo board. Since the device must be hot-pluggable, it is not allowed to...
I'm trying to set Timer 2 (32 Bits) from Nucleo L432KC to measure input signals up to 1 kHz (for example). However, I'm confused about the selection of the prescaler and counter period. I read in a book:Another relevant condition is that the UEV freq...
I want to use a 8MHz quartz for an STM32F765ZG, i want to know some quartz' references with passive components needed.
