Posted on January 04, 2017 at 16:25HiI have been investigating a problem with a product using an STM32F103R8T6 and USB virtual COM port. Code for the CDC was generated from the latest version of the Cube. The device is bus powered and the problem oc...
Posted on January 01, 2017 at 16:39hiI have a stm32f4 discovery board and i use stm32 cube.I want to create a 400ns interrupt but it doesn't less than 2.5us.my initialization are:TimHandle.Init.Period = 1;TimHandle.Init.Prescaler = 0;TimHandle.Init....
Posted on January 04, 2017 at 12:36Hi, I am trying to use the burst DMA mode to update the HRTIM compare unit registers on a STM32F334 with the STM32 CUBEMX. I am using this function to trigger the DMA update if I want to update the compare register...
Posted on January 04, 2017 at 10:20Hi allI would like to connect a battery to vBAT Pin for my Nucleo STM32L476RG.I'm wondering if I should remove SB45 resistor or not.If anyone could tell me what's the correct steps to build a vBAT backup circuitry....
Posted on January 04, 2017 at 08:15If i do not disconnect the STM32 Boards serial USB connection to the PC Windows 7 I gets an BSOD on shut down.
Posted on January 04, 2017 at 09:39Hi, I am using STM32CubeMX and I want to use external crystal for clock. However, I face some problems,1) I set Baudrate 9600 for uart2 and send data to computer but in computer I can read the data with 4800 baud...
Posted on December 30, 2016 at 11:13I am designing a new custom board replicating Sensor Tile.The problem is STM32l476jxx (sensor tile) is not using external crystal for core clock. its uses Bluenrg reset pin on the external clock oscillator input p...
