Hello, we designed a motor controller with three-shunt topology using STM32F302C8. Because this MCU only have one ADC, the motor control SDK documentation (UM2392) explains on page 20 that the 2 ADC conversions needed to get the 2 phases current must...
Hello,I have been tasked recently with porting some code from another microcontroller into the STM32H7. Right now I am taking care of the UART communication and some parts around that. And I would like opinions and advice about some things if possibl...
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 everyone,MCU - STM32f103CBTx, Flash - 128Kbytes, RAM - 20kBytes. I use MDK-ARM V5 (Keil uVision 5) and compiler is - default compiler version 5.In my program I try to initialize float array with length of 240, ( float array[240] = {0}; ) and th...
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...
