Posted on March 24, 2018 at 02:19I enable Ethernet in RMII mode, tried PHY address 0 and 1, Ienable FreeRTOS, automatically configure clock, etc. I set breakpoints (SW4STM32) and program waits in lwip's 'accept' function, the one that waits for conn...
Posted on April 01, 2018 at 16:23Hi there STM community. I am having an issue in getting my computer (virtual COM port, to be exact) to communicate with my STM32L053R8T6 board by DMA and USART. Here is my code for the DMA and USART part:&sharpinclud...
Posted on December 20, 2017 at 11:07Hi,I'm working with a STM32F105 board with USB, UART and CAN ports. I wish when I connect the board with a computer through USB, multiple VCP are detected.What I understand is that each interface in a USB compos...
Posted on March 29, 2018 at 10:39Hello there,Firmware Package for Family STM32L4: 1.10.0When using FreeRTOS timers, there is a bug in function prvProcessExpiredTimer (Middlewares/Third_Party/FreeRTOS/Source/timers.c, line 498). The last operation be...
Posted on March 26, 2018 at 06:30Hello,I was wondering if the resistor to pull down the BOOT0 pin is necessary for normal operation, assuming you want to boot from flash memory. I was trying to find on the datasheet (STM32F0 series) to try and find ...
