I was working on the MCU STM32F429 while it was connected to the PCB when it shorted unexpectedly. The PCB at the time wasn't being used to power the board, or drive the motors. The Power source was my laptop and no external batteries. The USB cable ...
In my nucleo L432KC, I have set Timer 1 for PWM generation, Timer 15 as a timer based interrupt and Timer 2 as PWM input mode. Timer 1 and Timer 15 works well until a point. For example, I wanted a 50 kHz update event, so I set Timer 15 Precaler 0 an...
I'm starting a project based on the STM32F215 MCU. I'll be interfacing to an SD card with the SDIO interface, as well as an LCD display using SPI. I'm looking at the STM3221G-EVAL as a development platform, because it has the SD card interface av...
I'm developing HID Host for working with standard PC keyboards.I face with problems in function USBH_HID_GetReport from cubemx, it never returns USBH_OK. Absolutly same problem explained here http://forum.easyelectronics.ru/viewtopic.php?f=35&t=23447...
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...
