Hello! I'm making an USB sound card and I need that it would have several audio channels configurations like at picture below. My thoughts about USB device topology:IT (1) - --------------- | --- SelectorUnit - FeatureUint - OTIT (2) - MixerUnit - ...
When you configure DFSDM faced with the problem that I can't see the status registers a custom filter, due to incorrect file STM32L4x6.svd because the register addresses according to this file do not match those described in the Datasheet and in the ...
I'm used mcu stm32l476vg.I'll have to low power mode.It is in low power mode using the following API.HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI);But although it is in low power mode, it does not return by USB insertion.I ask for yo...
when make ADC calibration, using while(HAL_IS_BIT_SET(adc->CR, ADC_CR_ADCAL)); makes system reset. CLEAR_BIT(adc->CR, ADC_CR_ADCALDIF);//single end SET_BIT(adc->CR, ADC_CR_ADCAL);while(HAL_IS_BIT_SET(adc->CR, ADC_CR_ADCAL)); //make system reset//...
I'm relatively new to STM32. Before I was a Freescale programmer.To practice I am writing small programs in order to better understand the structure of STM32Fxxx.I created a small program that generates two waveforms, staircase and sinusoidal, taking...
Hi. I've run into an interesting situation and hopefully someone can give me an answer, or at least a suggestion.We've got a product in development. In the last few months we've seen a couple of them (2 or 3, that we know of) freeze and become unresp...
hi I have an encoder that has channel A channel B 5 volt output only and I wonder if it is possible to read gpio interrupt with a cortex m4 since it works at 3.3 volts? Do you need a logic level converter, some resistor or read it anyway?
I have a STM32F303 acting as a serial port to an industrial control system, but I need a reliable way to set a byte for out-of-band data (I need to set "termination resistor On/Off, Drive Strength, etc -- I'm using the "comm port" for the serial data...
The SPI Bootloader function of the STM32F730R8T6 is being developed, using the pin of SPI1, but there is no normal response, and the response is 0xff or it takes a long time to return to 0x79.
I'm having problems getting an ADC value from the STM32F777IIK chip we have embedded in one of our boards.I have used a digital GPIO application and have confirmed that the ADC pin (PC0) is connected from the chip to the headers that is good.I have u...
