I am trying to configure the HS OTG port on the STM32H747I-DISCO dev board, but setting "Use external vbus" seems to be not enough. I can measure 0.8V on the CPEN line (measured from R11) but I don't see anything on the OUT line of the voltage switch...
STM32G473CB has 3 DAC channel outputs. a. Can these three DAC channels output a 100KHz triangle wave signal at the same time? b. In addition to the triangular wave, can the output signal output an irregular 100KHz waveform? thanks
Hello,I'm new to stm32 microcontrollers. I'm trying to figure out how to configure LPTIM1 in counting mode, external clock in using cubeMX. Is there any examples on how to set it up?Is this even possible?Thanks in advance.
Hi, I am using STM32G0B1KC ad usb device. I will show you all the conficuration for USB_DRD_FS and USB_DEVICE middleware.I am using the internal HSI48 for the USB clock.When I connect the device to my PC, the device is not recognized.Can anyone help ...
Will STM32H743BIT6 support only OTG_HS mode? Will it support normal USB operations by disabling OTG option? If yes which pin will control that functionality?
Hi, 1. In order to calculate the values of pull up & pull down resistor, in which section can we find the impedance information?2. Should we use external crystal for OSC_IN & OSC_OUT pins?3. If we are using USB2.0 FS feature what is the reference?Tha...
Hi I have a simple question about DFSDM configuration. I want to apply sinc5 with 32 samples length and therefore get 32 times decimation. Btw, I use internal ADC1/ADC2 in dual mode. STM32H725.Thus, for a given ADC frequency F I expect to get decimat...
Hello,I am new with STM32. We would like to do a current control exactly like on this document :https://www.st.com/resource/en/product_training/STM32G0-Analog-Comparators-COMP.pdfpage 13But we would like to use COMP1 for ZCD and COMP2 for overcurrent...
Hi,I am accessing a DRV8873s motor driver (SPI version) on two different NUCLEO boards. My usage is limited to reading data from 2 registries.I got it to work on a NUCLEO-STM32F411RE using SPI2, with the following settings:Motorola format, 8 bits, MS...
I've been trying to set up a timer and DMA to run a synchronous parallel bus onto a GPIO. The timer works great but the DMA keeps failing with a transaction error interrupt and disables the stream. This is on an STM32F413 chip and using TIM2_CH1 as a...
