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_...
Posted on November 02, 2017 at 14:36Hi,I'm facing a problem of getting the STM32F3 Discovery board bootloader to work. AN2606 calls for pattern 2 to be applied so I pulled up the BOOT0 pin. A check with STLink shows the nBOOT1 bit is 1 so upon power...
Posted on November 03, 2017 at 08:51HiI'm using a stm32f103ve development board and i want to run linux on it.I confront a version of linux named uClinux that is compatible with my board.ST has a pdf named AN3012 that describes the procedure of runn...
Posted on November 03, 2017 at 08:24Hello .,I am working on STM32 MCU in our custom board, In this I am facing some issues related to Ethernet interface. I manage to generate Ethernet code using STM cube MX,(Using in RMII), The code is working but n...
Posted on October 30, 2017 at 13:15I am working with STM32F765BIT MCU in our custom board, In that I need to measure some external signal frequency.I am using timer in input capture mode to measure the frequency. I have taken some reference example ...
Posted on November 03, 2017 at 03:59I am trying to use the HAL timer PWM DMA to implement something similar the TIM_DMABurst example in the STM32xG_EVAL directory but for more than 1 waveform.The TIM_DMA example in the STM32CubeMx STM32xG_EVAL direc...
Posted on November 01, 2017 at 20:58Hello!I'm designing a board with a STM32F2 series MCU and i was using JTAG as programming/debug interface, but now it's becoming out of pins and have no more free space in the PCB, the only option I have is to rem...
Posted on October 30, 2017 at 17:19HELLOI want to connect backup battery to STM32F746 DISCO but from datasheet I see VBAT is connected directly to VDD is there any way to solve this problem ??
Posted on November 01, 2017 at 23:01Need to sample 5 channels at 20Hz. Would like an interrupt when the DMA buffer is filled (50 samples). Waiting on boards to arrive and have a few questions:1) Does the ADC or DMA needs restarted after each conve...
