Posted on November 03, 2017 at 20:49Hi,It is shown at the schematic of EVALSTPM32 evaluation board , both 3V and 1.2V voltage regulator outputs are connected to ground via some capacitors. Is it mandatory to terminate these pins as shown in the sche...
Posted on November 02, 2017 at 16:13Hello,I am running the ADC_DMA_Transfer example on NUCLEO-H743ZI without any changes. And i see the ADC_DMAHalfConvCplt getting called when the aADCxConvertedData buffer is completely full and not half full as exp...
Posted on November 03, 2017 at 15:39Hello,I am designing a schematic with an STM32F407VGT6 (http://www.st.com/content/ccc/resource/technical/document/reference_manual/3d/6d/5a/66/b4/99/40/d4/DM00031020.pdf/files/DM00031020.pdf/jcr:content/translatio...
Posted on November 03, 2017 at 06:50Hi All,We are using STM32F0 controller in our project. we tried enable ADC with DMA one shot mode. Currently we configured 6 ADC channels(ch1, ch2, ch3, ch7,ch8 and ch9) with DMA support and we tried access other ...
Posted on November 03, 2017 at 13:26We have STM32F405RGT SPI-3 configured as a slave to receive the data from the master using HAL drivers. The DMA is configured to receive 128 bytes of data from the master in Normal mode and the NSS is managed by t...
Posted on November 03, 2017 at 02:51Hi, everyone.FSMC provides some memory space for interface with external memory, but can I use it only to store data without connecting with an external device?If not possible, what would be the most appropriate w...
Posted on November 02, 2017 at 10:08Is it possible to set LPTIM to have interrupt every ms?I did try some examples, and got PWM working with LPTIM on PB2.I can do that with TIM2, but then I got problem with system wake up, and I do not want that...
Posted on November 03, 2017 at 14:07Hallo, Since I think that the use of auto generated code using MXcube helps a lot, I have a question regarding the best workflow to use in the following case.My board is powered by an external power source. In thi...
Posted on November 03, 2017 at 10:36Hello, I am using stm32f769 bga package. We accidentaly connect VDD12DSI pin to VCAPSDSI pin and connect them to 3.3V VDD. We only gave power to the circuit for a few seconds. Could it damage the MCU? And if I dis...
Posted on November 03, 2017 at 10:59Hi there,I am trying to Transmit data over USB CDC after receiving a command, So I need call cdc transmit function inside cdc rx function in which I am comparing the received data. But i am able to use only 1 cdc_...
