I have a system that needs to run for years. But is in a place where it cannot be maintained. The desire is to have two processors, one running, and one in backup. The second can be powered down, or powered up, but in lowest power sleep mode. If a pr...
I use an SPI interface with Rx and Tx DMA to transfer a 22 byte buffer from a spi slave. Chip select is handeled withLL_GPIO_ResetOutputPin(TDK_nCS_Port, TDK_nCS_Pin);set to high again to end transfer I wanted to use:// SPI5 - IMU TDK Rxvoid DMA2_Str...
The backup SRAM cannot be accessed in the (normal) Run mode ?
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.
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 ...
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...
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...
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。
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 ...
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...
