STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
Hi everybody,I'm using STM32F411VE and compiling/debugging with IAR / ST-LINK.My firmware has a structure that must be non volatile and is, thus, saved on flash everytime the machine detects that the mains have been switched off (by z-crossing detect...
Hi all,I'm faced with a strange issue: updating the RTC calendar does not seem to be possible after a wake-up from standby mode.I have a piece of code that updates the RTC calendar (date and time are uint32_t):// rtc disable write protection RTC->...
Hi everyone ,We are using our custom bootloader firmware to update our main firmware.To do that we set a flag at a specific location at RAM and reset the MCU.The flag size is 1 byte.At the bootloader firmware read the data from RAM and if this data m...
