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...
I'm using an STM32H745 and have developed the Boot code, which works as expected when built as part of an application. However, having converted the Boot code to a static library and linked it into the same application the Boot startup section .isr_...
Hello,I'm writing a Flash HAL driver in order to understand better how this CHIP work.My functions at the moment work correctly but for some page I have an HardFault(During erase).For example I can't erase/write the page 0 and others pages.Please cou...
Hi Everyone,I am currently using STM32F103 for making a usb hid which acts as both, a keyboard and a gamepad.Please take a look at the descriptor and code below.Both of these work properly when used individually but when I combine them both and add r...
we are using EXTI1 interrupt in our project based on stm32f446. But the Interrupt handler is not firing.We looked into the interrupt enable registers, Mask registers, etc and all seems fine and a timer interrupt also in the project, which is triggeri...
Hi all,I'm using application note AN4636 for LC sensor.I tested with the example source code, and they work well for one sensor.But when I use multiple sensors, I face an issue. If I use the same value for inductor and capacitor for each sensor, the ...
I am working on STM32F407ZET6 with DMA+SPI in slave mode. Trying to reset DMA Counter when NSS is high to avoid shifted data transmit.TX and RX DMA are working on Circular mode.This is my tx data typedef struct { uint8_t InputState[4]; uint8_t re...
i am sorry for creating a lot of post recently but i just can not program my microcontrollers. when ever i try to program it i get this:STMicroelectronics ST-LINK GDB server. Version 7.5.0Copyright (c) 2023, STMicroelectronics. All rights reserved. S...
Hi,Is it possible to have a single ADC result transferred to two different memory locations using DMA without CPU intervention?Specifically I want DMA to take a single reading from an ADC, transfer it to one location on the STM32H747 CM4 and another ...
Hello,I'm trying to program G491KCU6 board via UART1 and I'm not able to connect to st-programmer. I don't know whether the board is actually entering Boot0 or not. I have PB8 with 10K to GND and I pull it up during connection to enter Boot0. Below i...
Hi,I'm trying to send data from ADC to FMAC directly via DMA in circular mode. From the STM32G4 reference manual (dm00355726) page 402:"Peripheral-to-memory, memory-to-peripheral, memory-to-memory and peripheral-to-peripheral data transfers"But I can...
