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?
How to do UART3 to UART2 File transfer in STM32G0B1R8T6N
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.
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 ...
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 ...
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...
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...
Hi,The package UFQFPN32 (5x5 mm) have an exposed pad but where is the definition of this Exposed Pad in the datasheet for the STM32F302K8 K Must I connect to the GND or is it not connected or maybe another pin definition ? I can't see in the datashee...
I'm using USART2 on PB3 and PB4 which means setting the AFR bits for those GPIO pins to 7. The CubeMX wizard and HAL GPIO libraries agree with this, but the AFR bits for PB4 stubbornly revert to 0 and my USART wont transmit. What is going on? I've tr...
