Posted on May 21, 2018 at 13:12when I am sending data using USB, when the callback in my firmware gives me USB BUSY? i am using STM32F303VC discovery board ......USB code generated using STM32CubeMX.Once, I received USB Busy state, dynamically send...
Posted on July 13, 2018 at 08:11Hello ST Team,I am working on STM32091C-EVAL board, and I need to work on SPI so loopback test preferred. But I am facing some issue while receiving the data, receiving 3 consecutive bytes(except 1st byte) repeatedly....
Posted on July 13, 2018 at 05:34I'm writing USB composite device CDC+HID(keyboard),but have some error(Unknow device descritor). I used USB FS Lib 4.0.0,and STM32 StdPeriph Lib V3.5.0 .Who has done the same procedure,can you give me a reference.Thin...
Posted on July 12, 2018 at 20:00Hello!The question is about reading values from Alarm registers (RTC_ALRL and RTC_ALRH) of the RTC module in STM32F1xx family devices. To be more precisely, the question how to be ensure about correct values. These tw...
Posted on April 19, 2017 at 12:06I'm using HAL_TIM library for my timer proposal. I would like to count 100 us. My idea is starting to run a MCU timer in free run mode and having and interruption every this timer period. I have read there are severa...
Posted on May 23, 2017 at 02:00Hi,I am having some issues with the Cube generated Ethernet startup code. I suspect I am discovering limitations in the generated code because of assumptions Cube is making of my hardware.For reference my setup is as f...
Posted on August 18, 2017 at 08:34Hi,I'm using custom hardware that has STM32F303VB (firmware version F3 v1.8.0) and uses USB in self-powered mode.I have modified USB Custom HID class to appear as USB Vendor Class (1 IN + 1 OUT endpoint). USB Vendor...
Posted on April 26, 2015 at 21:29I was struggling for quite a few hours to get the simplest UART input ring buffer working. As soon as an ''overrun'' error occurred, the thing stopped, while the code was prepared to handle that situation (or so I ho...
