I am using nucle-h745ziq ,SPI1 as Full duplex master and SPI4 as Full duplex salve.And both have same freuncy 25MHZ .And spi1 prescalar is 2.But SPI4 is not start the communication.Both structure parameter are same.In spi.c libabry I am uing if(HAL_...
We have three options to select encoder mode In SMS bits (Slave Mode Selection) of TIMx_SMCR register. Based on the description following each mode in this register, counter counts UP/Down on each TI2FP1/TI1FP2 edge based on the TI1FP2/TI2FP1 level o...
*How we can transfer (eg:2 bytes of ) data through simple GPIO pins without using any of the communication protocols (uart,spi,i2c,etc..)
I have a STM32F446 core and the Peripheral clock is 45 MHz. I am looking at the RM0390 Rev 6 Section 30.7.7 Bit TimingI am looking at the documentation Figure 395. Page 1063/1347I want a bit rate of 1 million bits per second (Mbps)In my calculation u...
I am trying to collect data from ADC using DMA in circular buffer mode.i want to excess/read DMA_SxNDTR register. also tell me how to read data from circular buffer. I have written code for reading count from DMA_SxNDTR but it is not working , it is...

I have had STM32CubeIDE v1.3.0 working with my hardware. I just upgraded to Cube to v1.6.1. Now when I try to debug, I get "No ST-LINK detected! " message box This has happened before (my upgrade to 1.4.1 failed so I rolled back to 1.3.0). ST-LINK...
Hello,I'm using nucleo board f410rb to communicate with another device via UART, my Baudrate is correctly fixed , i checked with the builder of the device the command i should send , i wrote the following code but the device dosen't respond uint8_t t...
I have RS-485 transceiver connected to USART1 (PA9 + PA10) and relay connected to PB4. If MCU have erased FLASH or RST-pin connected to GND all incoming data to pin PA10 (Rx) for RS-485 line translated to pin PB4 in inversion (0 on PA10 => 1 on PB4, ...
