Posted on October 28, 2016 at 17:45Hi all, We are trying to implement two CDC using an stm32l4. Both CDC works find with a win7 64 bits and also with Linux. We also get success using win7 32bit but only when we implement one CDC. We are using the l...
Posted on February 21, 2018 at 19:20Hi,I've successfully run a FreeRTOS program that use ADC + DMA in scan, continuous, circular mode and I successfully can average in HAL_ADC_ConvCpltCallback().Now I'd still like to use DMA to fill a buffer of 3 ch...
Posted on April 18, 2018 at 11:23I'm trying to use the I2C slave in DMA mode.uint8_t aRxBuffer;HAL_I2C_Slave_Receive_DMA(&hi2c1, (uint8_t*)&aRxBuffer, 1);But HAL_I2C_Slave_Receive_DMA returns HAL_BUSY.At the same time I have no other devices on the ...

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 ...
