I am using STM32f103 and Cubemx ide. I implemented small project 1 month back and that time it was working fine but now when i am trying to use same code then i observed weired behaviour.Code runs only after binary flashing and after that if i press ...

i am using stm32f103 for one project. Previously we were using UART interface to transfer data but now we want to use USB CDC interface for the same.i configured the usb in cdc mode and it is working also. I am facing one issue like data receiving is...

I am using STM32H7 MCU and Cubemx ide. I am facing an issue with ethernet connectivity with the Nucleo board which has STM32H743 mcu.I have configured Connectivity ETH and set the mode to RMII and enabled LWIP from the middleware. I tried DHCP enable...

I am planning to use stm32f767 mcu. I am confused to use clock for the same. I am referring discovery board schematic but in that NZ2520SB-25.00M is used for MCU and Ethernet controller. In my case i won't be using ethernet. I will be using TFT inter...

I am trying to resolve this pin mapping for the STM32f767 processor, FMC_D9 is connected to SDRAM so PE12. I am planning to use USB OTG so PA10 will be connected to PA10.So, with the above connection, only the pin is left that is PG12. How to resolve...

Yes, Here i am copying only 64 bytes. This callback gets hit whenever USB receives any data. So even if send 20-30 bytes then i am getting few of the bytes. Sure i will check with DMA as well.

Thanks for the reply. I want to use LTDC as a TFT interface. I think more package MCU will be a good choice. Is there any other MCU which has same package and i can use.

Posted on May 08, 2018 at 19:12Thanks.Now code is working on Power ON and i think it is writing to correct memory location.I could not read the value properly. i want to write Char Array to ROM. Is this write and read functions are correct?uint32_t...

Posted on May 06, 2018 at 21:34Is USB IAD interface is required for composite device? Is it possible to use HID and CDC interface without use of IAD?
