I'm using STM32F072VB.I want to communicate with 'USB' instead of 'Serial'.Should i use 'USB CDC(VCP)'? or Should i use 'USB HID'?I created a 'USB HID' test code with CubeMX and checked it. ( Reference Image1)<Image1>Can i do 'download communic...
I'm using STM32CubeIDE and created a project for the Nucleo-L476RG with FreeRTOS selected. I switched the Timebase Source to TIM6 to allow FreeRTOS to have SysTick. I created 2 tasks and 1 queue (for the default 16x queue size of uint16_t). Here are ...
Hello,I'm trying a really simple HID mouse-moving example (https://notes.iopush.net/stm32-custom-usb-hid-step-by-step-2/) and if I connect my bluepill via usb to the computer (macOS), as expected, it connects and the mousecursor slowly drifts to the...
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?
