USART1 interrupt only receives one string, processes it well and returns it back as expected. But when i issue the second string, the check USART_IT_RXNE status flag is always false. I tried to reset it right after the preceeding string is sent but a...
I have a simple switch on an LED project on a homemade STM32F405 development board. I am using STM32 Cube-MX and It is all working OK and turns an LED on and off via a momentary switch on subsequent button presses. The problem is that on starting the...
Disclaimer - my skill level is pretty low but I am very keen to learn :D I made this homemade STM32F405 evaluation board and using STM32 Cube-MX, Keil uVision 5 and a ST-Link programmer was able to upload a basic blink code example. However I am want...
Hello guys,I would like to drive ili9341 using that library --> https://github.com/martnak/STM32-ILI9341and I faced somthings that I didn't know about pins.My device is this --> https://tr.aliexpress.com/item/3-2-inch-320x240-320-240-TFT-LCD-Module-...
Hi,I have to to run my code in RAM on STM32H7 and debug it.I put my code in RAM_D1 (start address = 0x24000004) changing the linker file in this way: /* The program code and other data goes into FLASH */ _sl_my_Code = LOADADDR(.my_Code); /* pnt to th...
Hello,I suspect there's example code for reading and writing serial data through the USB comm port (ST-link cable) on the Nucleo boards using the HAL libraries. Can anyone point me to one? I've seen the printf() example which is half way there. Th...
Hello,If I understood correctly the a hard fault exception handler should catch all exceptions that do not have a specific handler that should execute when they are thrown. For example: if I enable button interrupts(say falling edge) and configure EX...
systick was getting disabled with __disable_irq() . is it possible to use __disable_irq() without causing any effect to systick?
Hi, I've had an STM32F411 development board for sometime and have done hobby projects with practically every peripheral on the board (audio output, mic, accelerometer, gyroscope, etc) programming both with and without the HAL. I'm now interested in ...
we are trying to read the line voltage register in the energy meter(em6400ng) using mod bus RTU over RS-485 protocol. we are assembling the packet in an array and sending it to the energy meter using DMA. also we are receiving the packet in a buffer...
