I just got started with STM32 and I was trying to make 1 second delay with " for() " loop based on CPU frequency with STM32F407 . I realized It takes more clock cycle to perform one loop in higher frequencies than lower frequencies. For example " f...
We want to use the STM32F10x MCU as a JTAG dongle. Can we make use of the TDO, TDI and TMS on the chip or they are use solely for M3 debugging? Thanks.
I am using a STM32 Nucleo F334R8 development board and upon plugging the board in to my PC, windows file explorer shows a FAIL.txt file with the following text: "The interface firmware FAILED to reset/halt the target MCU". This file first appeared af...
I am looking at options to replace my mostly obsolete design using an FPGA and old linear CCDs. I've already chosen a new linear CCD chip but I'm considering a handful of processing options. Our CCD alignment system currently uses 13 bits output to o...
Hi,I'm using the STM32746 Discovery board and some example code - the "QSPI_ReadWrite_IT" example - but the QSPI interrupts are not working correctly. Specifically the Status match interrupt never fires and the example code gets stuck. I've ported ov...
Hi all, I'm using a stm32f10x connected to a CANalyzer in order to verify the integrity of the CAN bus. The implemented process is simple, I have transmitted a CAN trace ( 11 bit ID + 8 bytes of DATA ) to the CANalyzer and it responses automatically ...
Hello everyone,I'm using USART3 on F746, but only RX/TX pins which are mapped to pins PD8/PD9.Besides that, I want to configure general output to pins PD10/PD11 (to control LEDs), but they don't work when I try to control them. I looked up the AF map...
Hello,currently I'm trying to use the LPUART of the MCU using the LL drivers but I encountered an annoying issue.In short:LPUART1_TX = PB6LPUART1_RX = PB7-> Tx not working, pin always low; Rx fineLPUART1_TX = PA1LPUART1_RX = PB7-> Everything working ...
Hi!I'm using mpu6050 and Nucleo-f103RB without MXCUBEi got problem with I2C communication.LED is blink in infinity../* Wait until SB flag is set */ if(I2C_WaitOnFlagUntilTimeout(hi2c, I2C_FLAG_SB, RESET, Timeout, tickstart) != HAL_OK) { return...
