RM0376 Reference manual for STM32L0x2 DocID025941 Rev 5 states in 14.9 "Temperature sensor and internal reference voltage" :The following formula gives the actual VDDA voltage supplying the device: VDDA = 3 V x VREFINT_CAL / VREFINT_DATAThis can't be...
On my STM32L151CB-A (external PCB), the following issue is occurring when using the internal Real Time Clock:I configure Date, Time and Alarm A using the initialization routines generated by CubeMX. The Alarm A is set to trigger 7 seconds after the b...
hi, all. I wanted to ask about The pipeline stages in the m cortex processors , i read that m0 has 3 stages and m0+ has 2 , which renders it more efficient , can anyone explain what that means?
The F4 board worked fine doing UART DMA. I start to regret this upgrade.Forget DMA and IT for now, just trying to get F7 polling working.First HAL_UART_Receive works, but the rest time out.Register analysis is unenlightening going by RM0385 referen...
I am using the core cycle counter to measure the read and write transfer speed of the QSPI flash memory. I am writing a 128,000 byte array and reading it. I calculate 690,000 B/s to write the flash and about 1.2 MB/s to read it. Does this sound about...
had anyone have the experience of <string.h> functions stop working and prevent the whole programm to proceed?
All connections are done on port D.This is my program code.I am using stm32f407vg disc board./* * lcd_programming.c * * Created on: 20-Aug-2020 * Author: SOBHIT PANDA */#include "stm32f407xx.h"#include "stm32f407xx_gpio_driver.h"void LCD4bits_Cmd(u...
I have an application who requires a stable clock source in the whole temperature range but the power budget is tight, so we chose to use the MSI in sync with an external low power 32khz clock.To save extra power we send the core to sleep while it's ...
Hello. This is my first project with CANBus and i have some questions:I need to interface to motorcycle canbus system, and it is running at 500kbps.All i did is tuned parameters based on scope timings to get 2us/bit. and yes, it did start working, ca...
Hello!I'm using a custom board with STM32F767 and external Flash memory connected to the QSPI (MX25L12835F).I want to create a simple test, where I read and write some data into the external Flash.In the first shot I want to use the normal SPI mode t...
