Hello,I have tried implement UART Driver only with LL Library. I'm using Nucleo-H745ZIQ. Reception through DMA is not happening. Data is not getting copied to the buffer. MPU Also Configured. I'm attaching the code. Hope DMA Configuration for Rx is o...
Hello, I just started using the Nucleo board and currently I am trying to connect two Nucleo G071RB by using I2C, using one as a Master and another one as a Slave.I, however, am not able to even get a clock signal coming from the Master (measured usi...
ia m using STM32h743II MCU and I am trying to transfer SPI data from the spi4 block defined as SPI MASTER to the spi5 block defined as SPI SALVE without success using DMA.I'm looking for any basic example that actually works for transferring SPI payl...
Hello, I tried to run the RTC DS1307 first using libraries available on the internet. It was not successful. Later I tried to run the communication "manually" but it doesn't work either. Please help. The module with DS1307 works on Arduino. Through t...
I am fairly new to STM devices and I have faced the same issues after attempting to follow their guides. The board itself is able to show readings of the sensors and such within Tera Term and whatnot, but whenever WiFi is involved, the device just se...
Hello, I have written a code for I2C to act between two Nucleo boards, however, at the moment, the master board is not even giving me a signal output. I looked at the output using a Saleae Logic Analyzer and there isn't even a clock signal comin out ...
I have configured my STM32G071 SPI peripheral to transmit 8 bits with the following code:void spi_config(void) { RCC->APBENR2 |= RCC_APBENR2_SPI1EN; //Enable SPI Clock //Configure for SPI mode (not I2S mode) SPI1->I2SCFGR &= ~SPI_I2SCFGR_I2...
ContextI am working on NUCLEO-U575ZI-Q with an external ADC wired to the board. The ADC generated a rising edge on one of its pins, "DRDY" each time a sample is available.My objective is to retrieve the ADC sample without involving the CPU. The curre...
