1.board-NUCLEO-H743ZI2 . we are dumping code into flash externally through USB .for that we are making boot0 pin high and low manually.is it possible to make boot0 pin high and low in software. I don't have access to change boot0 pin in MX.
we are not able to change boot0 pin in MX configuration. for other input output pins we are able to change the configuration but not for boot0 pin.Thanks in advance.
FDCAN between two STM32H747 MCU boards
I would be interested in implementing a FDCAN communication between two STM32H747 MCU boards. I have implemented communication on a single board in External LoopBack mode. However, I am having problems understanding how to connect the two boards. Do ...
STM32f407-Discovery : Configuration of I2S full duplex mode for using external audio codec
Hi, expert,I'd like to use external audio codec with STM32f407-Discovery.STM32 is master and Audio data is receved and transfered using I2S3 Interface.Below is connection between STM32F407 and Audio Codec.And I used I2S DMA for transfer and receive d...
Keyboard scanner library sought
I'm in search for a library of routines that allow for scanning keyboard matrices with or without diodes in various configurations. I've heard it exists for Arduiono but I'm pretty sure there is such for the STM32 series too (my target is an STM32F10...
STM32F105 contact with flash through SPI ,the MISO pin has bad waveform
When MCU（stm32f105） communicates with flash（W25Q64JVSSIQ）, it is found that the waveform of MISO pin is incorrect. Please tell me why this problem occurs。
Controlling a Nucleo-L476RG Board Wirelessly
I am starting a DSP class project that will be auto-adjusting blinds using the Nucleo-L476RG board. To start off, I am wondering how it is possible to control the Nucleo board wirelessly with an android phone. I am aiming to control a stepper motor ...
CAN Initialization failure then success
Hello,I have an interesting situation. When I start my app on the F303RE Nucleo I initialize all the peripherals. When CAN is initialized it returns a HAL_TIMEOUT error. If I call the same initialization code a second time it initialized correctly...
STM32H743 jumping to wrong interrupt when I move the vector table when using LPUART
I have an application using STM32H743 we wish to use the LPUART using the interrupt. We have a bootloader that is located 0x08000000 until 0x08020200. According to system_stm32h7xx.c we should move the vector table in steps of 0x200 this works for al...
Need RTC Configuration in wakeup counter mode with 1sec wake up time and LSE as Clock source.
Hi Team,Need the RTC Code base with LSE as clock source in wake-up counter mode and needs to get the interrupt at every 1sec rate.We have some queries regarding the LSI Clock source which is in example project.If we use the LSI as Clock, calibration ...
