Resolved! RTC LSE Bypass - I wrote code that RTC works with HSE as clock in, but the same code using LSEBYP w/ external 32KHz oscillator can't get past LSERDY not INITF. Any docs found so far mentions LSEBYP but none indicates how it all works together.

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...
