Posted on February 27, 2018 at 01:05Hey. STM32F746 device transmits constant lenght-garbage bytes from a cdc device while working in composite with MSC interface as well. While enumeration, receiving and SCSI functions work perfectly fine, device se...
Posted on December 21, 2017 at 13:32Hello, In STM32F41xx, we are facing the problem to send data to PC. Actually we are using CDC_Transmit_FS function to send 60 bytes data to PC. But code getting stuck in if (hcdc->TxState != 0) return USBD_BUS...
Posted on May 19, 2018 at 16:28Hi,i was using CDC_Transmit_FS api to send data serially. It is printing as well but if i give string length more than 30 approx. then CDC doesn't send data.if i gave length as 20 then it works for same string.Is there...
Posted on December 20, 2013 at 16:22I'm working on a dfu bootloader for stm32 (f4) devices (https://github.com/swinman/dfu-programmer stm32 branch). I'm using the stm32f407vg and have gotten everything working except the read operation. When I cal...
Posted on April 19, 2018 at 17:04Hello,I'm currently using a STM3210C-EVAL board with FreeRTOS, and I wanted to communicate with it through Ethernet.However, the program stops working when this function is executed in HAL_ETH_Init :(heth->Instance)-...
Posted on May 20, 2018 at 21:14I have a client/server LWIP program that works correctly with unicast communication however I want to use multicast features so I used IGMP library did the following:1- in opt.h:&sharpdefine LWIP_IGMP 1 //allowed IGMP2...
Posted on July 13, 2018 at 08:56Dear Community,Is there a place that we can contact the developers of HAL in a more formal manner than this forum?Any how, I see that HAL provides separate date and time functions to set and get the date and time:- HA...
Posted on June 19, 2018 at 19:27I'm trying to find a way to use a delay of 300microseconds in my code. I'm currently using a F302R8. I'd like to do this without using interrupts for the time being, if possible. Is there a HAL_Delay_Microseconds a...
Posted on July 14, 2017 at 11:59Hi everyone,I'm working with an STM32L476VGT microcontroller and I'm trying to use USB_OTG_FS in Host_Only mode for reading and writing on an USB Drive. I also have a STM32L476 Discovery board but cannot find any exam...
