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...
Hi, HAL_UART_STATE_BUSY_TX is always Set when I change the ClockPrescaler of USART Paremeter.My Cube configurations are in photo above. I have to drive Usart with 100 Baudrate. Systemclock Frequency is 50Mhz. When SystemClock is 50Mhz and ClockPresc...
Hello,I'm currently working on a project using the STM32L431CCTx microcontroller from the STM32L4 series. My goal is to retain specific variables in SRAM2 across MCU resets to maintain state and ensure data integrity using a CRC mechanism. However, I...
Hi all! Hoping someone can help me with this. Right now, I have Timer A and Timer B as my main outputs; Timer A controls one set of switches in my half bridge, and Timer B controls the other half. I have one "mode" set, where I can adjust the phase s...
We want to light up an LED when a hard fault occurs.Please tell me in which handler I should put the GPIO processing.Also, We would like to turn on the LEDs for faults other than Hard fault, is that possible?
Hello,I am using STM32CubeIDE to implement an application under FreeRTOS on a STM32F107 chip installed on an Olimex board.I also need a USB communication with a PC computer to exchange commands and data between our software on both sides (application...
Hi all,I'm trying to acheive STOP mode on my stm32f405, but ir's hard to come down 1mA as de datasheet say < 100uA. So to explain my project :- STM32F405 Freertos- 3 i2c capteur (power of captor is managed by switch)- 1 spi flash nand w25n01My clock ...
Hi all,I'm trying to understand what source the STM32H7 (specifically STM32H743) uses for the TPIU trace clock.According to the RCC chapter there ought to be a multiplexer that allows to choose from a number of sources:According to the debug chapter,...
Many engineers I know use HT7533 as power supply for STM32F105RBT6 in automotive boards. I looked up the specs, and found that HT7533 is only rated for 100mA. Is it too low for STM32F105RBT6? Is TI's TPS7B91 or TPS7B92 better in this case? Thank you.
Hello everyone, Using the STM32H723VGT6 chip, the program can be downloaded and run normally, but cannot be erased and uploaded, prompting "Error while determining flash info (Bank 1 @ 0x90000000) Failed to read back". The same phenomenon occurs wh...
Hello all,Regarding the STM32H725 bulk capacitors:Question 1:Is the capacitors required values taken into consideration the capacitance degradation Vs DC bias?For example:The SMPS input required is 4.7uF (10uF recommended)Looking at the STM32H735G-DK...
