Posted on July 22, 2016 at 10:39Hello friends ; We have a datalogger based on stm32f4 discovery ; we log the data in external flash disck 8GB ( scan disck ) ; we noticed that about 20% of the usb discs we used don't work . STM32f4 detect the usb ; ...
Posted on December 07, 2016 at 21:08Hello all,i am working on a project which implies the control of a BLDC motor in 3 phases.For this type of motor the switching of the phases must be sync with monitoring the 'back-emf' signal from the unpowerd pha...
Posted on December 08, 2016 at 09:52Hi, What are the back up register and what is the goal of these registers to wake up a device from a low power mode.Thank you very much !Have a nice day ! #backup-register #low-power-mode
Posted on December 06, 2016 at 22:28Hello!I've come across this strange problem where I can't seem to find a reasonable explanation why it occurs:I am using a simple RTOS, I have an EXTI interrupt handler that calls a simple function which sets a fl...
Posted on November 28, 2016 at 00:47I have managed to get a VCP/CDC bootloader going and the ability to use USB to tell the unit to go into bootloader mode from the main application. I do this via a Qt program running on Linux (as well as Windows an...
Posted on December 08, 2016 at 04:59RM0365 (DocID025202 Rev 6) states COMP1INMSEL can be set to 101 to enable PA5 to be connected to the inverting input of the comparator 1, but in 'Figure 118. Comparator 1 and 2 block diagrams' and 'Table 102. STM3...
Posted on August 18, 2016 at 16:50 I have a custom board with STM32F446RE, with RTC powered by coin cell batteries. After testing 2 boards in the field for several days they stoped working and, while debugging, I realised that there a timeout in...
Posted on December 06, 2016 at 22:05Hello, We are using STM32F072 series MCU with 8 physical ADC input channels and VBAT internal by configuring DMA with continues conversion mode:/* ADC init function */ void MX_ADC_Init(void) { ADC_ChannelConfTypeD...
Posted on October 22, 2015 at 12:34i am looking to write an application making use of the on board LIS3DSH accelerometer. However, the examples provided (and pointed to by the documentation) all make use of the old LIS302DL accelerometer. Does anyon...
Posted on December 06, 2016 at 04:17Dear Community members,I'm developing a device which is based on a 'Master - Slave' communication architecture, but now I encountered with a data loss while the Slave is receiving. Since the case is occasional, I ...
