SPI Mater<->Slave communication problem (slave starts to send 0x0010 after some while)

Hello, I'm working on a project with 2 STM32F4 that are communicating by SPI. The Master (running on 168MHz) is sending packages with 10x16bit every 1ms and 5.25mBit/s. The CS signal is connected to an EXTi pin of the slave that calls a DMA SPI tra...

What are TIMx TIx[1..15] input signals?

TIM1 section figures 55 and 79 in G0 reference manual RM0454 Rev2 refer to TI2[1..15] as selectable sources for TI2 signal (see also TI2SEL register bits). It appears that TI2[0] is the TIM1_CH2 pin, but what are the sources for the TI2[1..15] signa...

STM32F745vg Hardfault handler.

sir,Am uisng STM32F745vg controller for stepper motor controlling through a driver.while running program am getting hard fault handler .can you provide why hardfault interrupt occure.what is the solution for hard fault handler.

Can you use SPI in DMA mode interfacing with a SD card? If so is there an example code?

Can't connect using the I2C Bridge and the ISB042GUI "it's not possible to read the device mode information"

Hi, I'm having trouble with the ISB042V1 evaluation board and the I2C bridge dongle. I believe I have everything wired correctly, but I get an error message when I press the "Connect I2C Bridge" button on the GUI.I have provided 5V power to J2 as in...

How PDMS bonded to SU8 that covers microfabricated gold electrodes affect their electrochemical activity?

We microfabricated gold electrodes and coated them with SU8. However, when we bonded PDMS onto the SU8, the electrochemical activity of the electrodes dramatically decreased. Any ideas what could be the reason?

Send UART hex command

HiI'm trying use DFR0534 with STM32f446.This module read uart command hex.Ex. Command AA 07 02 00 08 BBIm trying send like thischar play[6] = {0xAA, 0x07, 0x02, 0x00, 0x08, 0xBB}; HAL_UART_Transmit_IT(&huart4, play, 6);But in uart monitor recive diff...
