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 would like to access the UID_BASE (0x1FF1E800) register from the CM4 core, but I run into a HardFault. I checked the reference manual and page 137 says that memory map is reserverd for the CM7.Is there a way to read it somehow to map that System Me...
HelloI'm developing firmware for a STM32F413 on a PCBA. The controller needs to:- control two ADCs via one SPI,- control an LCD via another SPI,- de-bounce a switch using a timer and - communicate with a UI interface over a UART.The SPIs and the UART...
Hi there,I'm trying to implement a software interrupt using the STM32L432KC. I want to trigger an interrupt when I reach a certain point in the code. Unfortunately I didn't find any helpful example.Once I tried to set bit37 in the IMR2 register.SET_B...
Hi, I am using stm32l0 series. my device will work with battery. I want to put it in sleep mode when it is not working so that the battery does not run out. Then I want to be able to see the battery status. But I have no idea how to do it. What I wan...
Hello,I have a custom STM32F439VITx board running at 60MHz clocked from the HSI. I have three devices on I2C3, two of which function correctly, the third, an mb85rc64 non-volatile memory, fails on both read and write operations.The I2C is configured ...
I ask about G071 exampke code, but nobody replies, then i try use more specific question. My test display is round 240x240 SPI LCD. TE signal is fmark .(one pulse per frame)In partial or block window send method RAM in display is updated on random pl...
I place oscilloscope probe at reset pin of MCU it get low reset continuously time periodI observed RCC- CSR resistor which gives LSIRDY=1 AND IWDGRSTF=1 both are set How can I make them of and solve this reset problem?Below attached images of MCU ...
STM32F746 Disco, UART1 connected to integrated ST-Link, Windows 10, STM32CubeIDE 1.7.0, Putty on PCI'm writing my own implementation of UART on registers in C, have datasheet and reference manual right here. I have no problem sending one character or...
Hi,device : STM32G473VBT6What is the best way to process SPI data when we don't know how many bytes will come from the SPI master ?I use the SPI in full duplex slave.The problem with DMA is that the DMA buffer is circular, where my processing functio...
