Posted on September 21, 2016 at 14:24Good afternoon,I am developing an application on the L4 discovery to log data on an USB, using FATFs and based on the example project from the STM32F4 library.The initialization seems to go smoothly but when I ca...
Posted on September 20, 2016 at 19:00Hello everyone,A week's search didn't bring me very far, so I thought I should ask You guys. I have some experience using Arduino, but this is my first hard-core microcontroller project and so far the learning cu...

Posted on May 30, 2016 at 13:21 Hi, I have emulated two VCPs with only one USB Device. I can send data in one VCP that has the following Endpoint Address. #define CDC_IN_EP 0x81 /* EP1 for data IN */#define CDC_OUT_EP 0x01 /* EP1 for data OUT ...
Posted on June 08, 2016 at 12:25 Hello. I want to make an UDP communication using mySTM32F407 based board, where the PC forms the server side. I checked most of the posts related to the Ethernet+F407 topic, but could not find any c...
Posted on September 15, 2016 at 12:03Hello All,Does ST provide source code for a starting point on bootloaders for the STM327x family?If so, can you point me to the source code?Thanks In Advance,John W. #stm32f7x-firmware-bootloader
