Posted on March 31, 2017 at 23:39I am using the USB CDC library on a STM32F746 as created with CubeMX and have run into a problem when the MCU transmits at the same time that it is receiving over USB. I had a PC bursting data to the MCU. The data ...
Posted on April 11, 2017 at 07:41 I have generated a project for USB CDC VCP using CubeMX and HAL and now I am trying to figure out how I can implement these two weak functions: void HAL_PCD_DataInStageCallback(PCD_HandleTypeDef *hpcd, uint8_t...
Posted on April 09, 2017 at 08:13Hi dear friends,I have a problem with uart reception.I can't receive any data or maybe i can't init it correctly.I assign gpio to it and init it according to user manual. it has transmission but no data can receive. ...
Posted on April 10, 2017 at 12:28Good mornign,I'm working in my application that is based on STM32L475 device.I'm able to flash my device by using the Dfulse Demo software and setting Boot0 to 1 when applying power to device. But I would like to imp...
Posted on March 16, 2017 at 10:54 I found a bug in the new Cube Version. At line 1 internal oscillator is enabled although it is not used, in fact it is not actived: RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTY...
Posted on April 05, 2017 at 20:36Good evening everyone,I'm trying to use the L433 USB as VCP using HAL Drivers, to receive data from PC and transmit the response to the PC.I'm following the STM32L452RE example 'Standalone CDC' from the CubeMX exampl...
Posted on April 03, 2017 at 00:53 Everyone, Does anyone know where I can find a simple example for FreeRTOS on Mutex ? I want to do two task but the first task never finishes and jump already to the second one because of the systick, how can ...
Posted on April 05, 2017 at 07:49static void DMA_SetConfig(DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength){/* Configure DMA Channel data length */hdma->Instance->CNDTR = DataLength;/* Peripheral to Memory */if...
Posted on April 04, 2017 at 19:41Hi all, I am using CubeMx generated code for USB Host- CDC communication. With this code Enumeration fails under two scenarios1) Host attached to a CDC device(CDC device not powered externally) then Power on Host.2) ...
Posted on August 26, 2016 at 16:48 There is a bug in HAL in full duplex I2S. The internal callback in the library disables all further DMA requests even if circular buffering is enabled. This is incorrect as it requires that an application call ...
