We are using a GPIO pin in STM32H743IIK6 microcontroller in open drain configuration. In datasheet, it is mentioned that Vol = 0.4V at IIO = 8mA and Vol = 1.3V at IIO = 20mA. What will be the Vol voltage at currents higher than 10mA? How does Vol var...
When the bootloader is updated from the main appli, the start address at reset can be set to the start address of the main application. By this, it is assured that the device can still be started if the bootloader update could not be completed, e.g. ...
I am trying to transmit character over USART2 using STM32L476RG EVB. I am getting "NUL" at the debug terminal instead of the transmitted data. please help. Here is the code and debug terminal:Debug Terminal#include <stdint.h> #include"stm32l476xx.h" ...
Dear sir/madam,I want to implement a USB audio DAC . And I have already followed the USB library for configuration of related files. When I am connecting the stm32f401VC discovery board USB connector to the host pc its displaying in the notification ...
Hello.I am using STM32C0 to do FLASH writing, I want to use 4 pages from page12~15 to do FLASH writing because the data I want to write in FLASH is not enough for 1 page.Currently(1) FLASH unlocking(2)page12 flash erase(3) page12 FLASH write---------...
HiI'm using STM32H753 and I enabled the icache and dcache , generated the code , and run it.The function SCB_EnabIeICache() ends but SCB_EnabIeDCache() is stuck.The project is an empty one.What can be the cause of it ?Thanks!
I am setting up Timer 1 channel 3 on the STM32F4. I am looking to set up a period of 3.9ms or 256kHz. I am using ABP1 - 168kHz, the ARR is set to 65535, and a prescaler of 10. 65535 / ( 168,000,000 / 10) = 3.9msMy timer initialization is below. _t...
Hi STM team,We are using stm32h747, with CM7 we are reading ADC value in polling mode, when source is not conneted still we are reading 0.5 to 1.8 volts, when the temperature increases from 40 C to 60 C this ADC voltage reading increase with rise in ...
Hi,I see an alias, using DFSDM (sinc3) and a PDM mic at 16kHz, while a speaker produces 1...24kHz.The spectrogram is attached.As I understand, the DFSDM filter has a notch at 16kHz rather than at 8kHz, and attenuates 8kHz for 12dB only.Is it possible...
I am trying to figure out SPI communication between two microcontrollers: I have an STM32H755 Nucleo and a Nucleo G47RE. I tested basic communication by shorting MOSI and MISO on both boards separately, and it works in full duplex master mode. Both c...
