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 am newer in STM32G030 develop.I tried to set STM32G030F6 I2C2 slave mode with PC.Q1.Using "HAL_I2C_Slave_Transmit(); it seems Master (PC) read 8 bytes later and stop. The other data will not read.Q2. If used HAL_I2C_Slave_Transmit_IT(), It only wr...
Hello,I've followed all the steps required to generate and handle a RTC wakeup in the manual, but it still doesn't work. I can't figure out why that doesn't work.The goal of the following code is that, when I click the reset button of my nucleo L152-...
Im using a STM32L412KB for the first time and Im a little confused about the clock options. I can't seem to change the clock speed (input frequency) in cubeIDE, it's always stuck on 8MHz. However I notice there is an internal oscillator - does this m...
In the datasheet of the STM32F765ZI and many other datasheets I have read, the specification value of hysteresis voltage between Schmitt trigger switching levels is missing. There is a comment (8) under the table (here table 66 I/O static charasterit...
We want to realise a cheap measurement of a external voltage over a voltage divider with a STM32F765ZI processor. We calculate VIL with the formula "0,35*VDD-0,04" which is guaranteed by design. On base of this calulated VIL we calculate our voltage ...
Is there a way to connect them in parallel with some individual enable to reduce the outward interface of the board. ie maybe connect everything in parallel except for RST line or ??? any suggestions would be appreciated
I have a bootloader + 1 wire serial uploader codebecause of space restrictions it uses LL_ libraries for initialization.We have different hardware designs, when using PA2 as IO pin it works !when using PB4 as IO it does not !The main program uses HAL...
I'm trying to setup a GPS sensor (UBlox Max8Q) with a H745 Nucleo board using UART DMA using STM32CubeIDE. However, I’m having problems with setting up my board properly. My plan is to eventually do all my data acquisition on the M4 chip and do compu...
We are evaluating the use of ETM or ETB but have problems finding MCUs that support those features (or one of them). Sure we can dig into the data sheet of an MCU family but isn't there a possibility to filter for these features in some MCU finder?
