Posted on July 17, 2015 at 15:44 Hello everybody, First I have to say that I never implemented I2C with interruptions. I searched on this forum and on the ST libraries a functional and simple send/receive I2C code working with interruptions a...
Posted on July 23, 2015 at 10:28Hi, all!Didn't found any mention about transmission of data for Low speed devices, connected to USB host via Full speed Hub. Is it really possible to use STM32F405 USB controller in host mode for such a sittuation?De...
Posted on July 22, 2015 at 13:21I am using the STM32F7 Discovery board (STM32F746NG) with an external I2C slave connected via the headers (I2C1 with PB8 and PB9). The I2C peripheral in the F7 is the same as the one in the F3, F0 and other STM32 devi...

Posted on July 21, 2015 at 10:45Hi all, I am working with a STM32F103 MCU. In this MCU, some pins have multiple alternate functions such as PA8 which has the following alternate functions ''USART1_CK/TIM1_CH1/MCO''. If I simply define such pin e.g. ...
Posted on July 21, 2015 at 21:19I am having some issues with the CDC Transmit Library.I have a STM32l0-discovery board, when the device is powered through the st-link usb connector. Whenever I transmit data over the Virtual Comport using CDC_Transmi...
