i am currently using the serial pins and a FTDI chip to communicate with a PC. I want to know if there is a way to use the on board mini USB port or the OTG port to communicate with the PC.
I'm sending a continuous data stream from uC to PC via VCP which is implemented as CDC. During stream every responded IN token for EP1 generates DIEPINT_XFRC, so I'm seeing interrupts:DIEPINT_XFRCDIEPINT_XFRCDIEPINT_XFRC...Now I send something to uC ...
I'm struggling already many days getting the most simple VCP functionality working in my application.I tried implementing the UM1021 usb OTG lib provide as extension on the STD peripheral library from ST, but without succes. After that I tried the s...
I'm need to use a microSD card on my new project, so I decided to test in my evaluation boards. I have a STM32373C-EVAL and a STM3210C-EVAL boards. For the tests I used 2Gb, 4Gb, 8Gb and 16Gb sd cards. Now came the problem, on the STM32373C-EVAL only...
Hello,I want to develop a system in which i am interfacing stm32l496 with BG96 module. I want to communicate with azure server using TLS1.2 and MQTT data protocol.i have already referred sample code given by ST but it uses wifi connection. However i ...
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 - ...
