Posted on July 19, 2016 at 06:13Started an example project generated by CubeMX and plugged the USB cable into the development PC. Please observe the following error. I think the report descriptor might be ill-formed: it's only 2 bytes, and ends wi...
Posted on July 22, 2016 at 22:58What ppm accuracy is needed for STM32F103RB as full-speed (12Mbits/s) device? Is RC HSI (a few percent error) not accurate enough for STM32F103RB as USB device? For STM32F401RE, do host or OTG modes require higher acc...
Posted on July 22, 2016 at 10:28Hi, since the WWDG of the STM32L0 series can be deactivated only by a hardware reset I don't understand the purpose of the function HAL_WWDG_DeInit in the HAL (v1.7.0). The function and its description suggest, that I...

Posted on July 18, 2016 at 21:20In my project on ''Nucleo STM32F411RE + OLED display SSD1306'' I detect:function HAL_I2C_Master_Transmit_DMA correct execution only first time,next calls is failore (data not transfer to display). Its for STM32CubeMX ...
Posted on July 18, 2016 at 19:39Hi, Got a weird enumeration issue on a USB device in my USB host implementation. Using STM32F746Discovery with CMSIS/HAL, re-utilising one of the provided USBHost library examples. I have a specific external USB devic...
Posted on June 29, 2016 at 03:30I've generated a test app using STM32Cube for a STM32F407 Discovery board and have been able to send and receive. I am now trying to port the code to run under microC/OS II. I have modified the ISR to include the uC...
Posted on July 16, 2016 at 21:37 Hi, I need to measure the time a PWM signal spends high. I have the input capture side of this working fine, but with IC mode set to both edges, there are occasional issues with the signal measurement. ...
Posted on September 18, 2014 at 18:08Hello Friends, Can you please advise me on an issue (which is most likely to be due to an error I am making). Using STM32Cube version 4.3.1, I put together a project for a Cortex M4 that will use USART1 in asynch...
Posted on October 19, 2015 at 13:48Hi,for last three days I try to communicate with my STM32F042 (working in slave mode) but it doesn't work correctly. There is no data in RXDR and busy flag is set after correct receive of address (ADDCODE flag is s...
