Posted on November 12, 2014 at 08:42Hello,I am interested to make USB HID HOST which can communicate with custom hid device instead of mice or keyboard.For that I have to send data to that custom hid device.I have used below fuction for dataoutUSBH_...
Hey there,I want to use a LIN BUS communication with my STM32F01CCT6 microcontroller. But i cannot see any example in internet neither in datasheet of my MCU. Is there any example LIN Transmit and Receive example that i can use. Thank you
Posted on May 22, 2018 at 21:45Hey guys,i am using a custom board with a STM32L452CE MCU. I am trying to implement a 2 Line SPI with a sensor as slave. Communicating via Transmit and Receive separately works fine. However if I want to switch to Tran...
Posted on June 13, 2018 at 08:07Hello I'm trying to make a usb vcp demo by using cubemx. I'm using the standard configuration. However there is a windows 10 driver problem. I tried it in 4 different computer. How can I find the proper usb ...

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...
