Posted on September 28, 2017 at 08:36I have designed a custom board with stm32f407 mcu and included USB OTG FS functionality in it. For USB OTG I have followed similar schematic like the one shown for stm32f407 discovery board. I downloaded a firmwa...
Posted on April 02, 2018 at 08:01Hi I want to communicate between two STM32L4 MCU, and interfaced RF on to UARTs.UART1 -- BLEUART2 -- XBEEI want to make a transparent, i mean when there is NO BLE there should be a switch to XBee and the other MCU ha...
Posted on March 31, 2018 at 19:38Hello everyone i've been working on a project using STM32F746g and i found many diffculties but this one is the most hard one and i couldn't solve it for weeks, i can't acces the SD card, tried everything /solution i...
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...
