Resolved! Sometimes, WWDG was not working and CPU hang
My company uses the STM32G0071CB chip. but I faced some issue.whenever I need to reboot main board, I have to reset the STM32G0071CB as wells.so I used the WWDG for resetting the chip.But sometimes, chip was not reset and CPU hang.(once a 400 times o...
SMT32h750 - Placing the math library in a specific memory section
Hi I need to place the math standard library in a specific memory section (otherwise, It won't be linked appropriately - luck of space)so I add to the ld file the following lines: .mylib : { . = ALIGN(4); *(.lib*); *(.libc) *(.libm) *(.libdsp); ...
UART DMA Rx STM32H745 with LL
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...
Connecting two nucleo boards using I2C.
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...
basic working example for SPI usage between 2 different blocks
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...
Resolved! I2C problem. I can't get the communication to work on STM32F0 Discovery in STM32CubeIDE. Where is the error in reasoning?
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...
How to connect to AWS or any cloud services using STEVAL-STWINKT1B or B-L475E-IOT01 Discovery Kit?
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...
Enabling SDA and SCL pins in the Nucleo board for I2C communication.
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 ...
