Hard fault on SPI write DR register
I have a STM32L412 on a nucleo board. In the debugger, the processor gets a hard fault after a random period of time. I have narrowed this down to when my app writes to the SPI DR register. Most of the time, this works ok (I can drive a TFT display),...
Resolved! GPIO IRQ call back handle pin - PA6 ,PI-6 ,Pj6
I am using STM32H750 MCU . I configured 14 GPIO as interrupt and handle in HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) function. In few GPIO pin number is same and different port .(PA6 , PI6 and PJ6).How to find proper interrupt PIN?

Clock generation using GPIO pin
Hii Guys, I am using stm32l053 microcontroller custom board . I want to generate 24 clock pulses on PC2 pin . Is there any possible solution to this problem ? How can I generate exactly 24 clock pulses on this pin?Thanks.
I2C communication between 15 STM32F401RE Controller
Hi,I am thinking to use stm32f401re microcontroller in my project, my Project application is such that I have lot of IO Lines(approx 700) so my controller is 64Pin controller and I may need approximately 15 controllers to capture all my IO Data, and ...
Resolved! How do I process just UART RX interrupt events while using HAL_UART_Transmit_IT
I've run into another hurdle I don't seem to be able to solve myself while trying to learn embedded STM32 programming. I have a simple test program that transmits characters over a UART with the RX and TX pins looped together and receives them using ...
Problems with interfacing LEM current transducer with NUCLEOL432KC.
I am working on a project wher i am using a LEM brand current transducer the model is HTFS 200, was proposed to measure a 250Amps line, but really i have no idea how to adapt the transducer output to the adc of my board, i would appreciate any suppor...
error HardFault_Handler in HAL_FLASH_Program STM32F303K8
I m a beginner with the FLash and I struggle to find a solution to write and read in FLASH.I wrote the following program but at the function HAL_FLASH_Program the program goes in HardFault_Handler . Looking inside the HAL_FLASH_Program it is possible...
