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...
Hello,STM32L476 data sheet Rev 8 talks in 3.15 about "Down to 18.75 ns sampling time" while table 77 only lists a minimal 31.25 ns minimal sampling time. Is 18.75 ns sampling time possible and with what setting?
HelloI am working in dual bank mode with STM32G474RET6 MCU. I want to store some default values in internal flash beyond last programmed firmware's data address.For example I have following contents in flash (shown from STM32CubeProgrammer):Data star...
Hello everyone, for a project I try to build a small CAN Bus with several Nucleo 144F207 Boards. Sadly, I have a really hard time to get it to work even though it should be rather simple. The minimum setup consists of two boards and two CAN Trancie...
I am a begginer in the st enviroment, but still. I'm trying to use the touch sensing library, but there is very little good examples of how to just use one button as a sensor. I real all the documentation, still no good examples. I downloaded the lib...
Why STM32G431 CAN get into bus off status? I cannot find the reason in the reference manual.
Hello,I'm new in ARM programming, I'm trying to study how CHIP work using the documentation.I wanna unlock the flash memory and according with documentation:1. Write KEY1 = 0x4567 0123 in the FLASH key register (FLASH_KEYR)2. Write KEY2 = 0xCDEF 89AB...
Hi, I'm using the STM32G030 MCU and I want to perform programming using the CLI commands. When using the STM32 ST-LINK utility and opening the option bytes window, I can see the PCROP bit which if I set, the MCU performs a mass erase when RDP bit cha...
Hello!What is the difference between JTRST and NRST of stm32 mcu?When using SWD, where should the RESET pin be connected? NRST or JTRST?
I have my own little board: with STM32U575CIT6Q (LQFP48 package). The USB is very simple and just DM (PA11) and DP (PA12) are connected. No USB-C, no USB-C Power Detector neither external chips for USB-C (as on NUCLEO-Board for USB-C-power).I want to...
I use the OCTASPI as QSPI. So far ok (QSPI transactions work).But I have realized:a) the QSPI does not release any signals after a transaction has finishedb) it does not seem possible to use OCTASPI (in QSPI mode, maybe as well in single SPI mode on ...
