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've flash erase problem after reset.My source code routine like this:1) Boot code start at address 0x08000000 2) Than read eeprom value if eeprom value is User value3) And jump user application. ( To 0x080A0000)4) After the successfuly jumping, I ge...

I'm using the STM32U5 and when I create a basic project in Keil and compile, I get the following error:"Error: L6218E: Undefined symbol SECURE_SystemCoreClockUpdate (referred from system_stm32u5xx_ns.o)."How to fix this?I don't want to use STM32Cube ...
Hello, I'm trying to set up SPI communication between an MCU as master and the STM32 as slave. Data reception in the STM32 works fine, but I'm not being able to transmit data to the MCU from the STM32. I'm using the interrupt callback to read and sen...
Hello,I'm using STM32 NUCLEO board.In my application, I want to read GPIO PORT A input register (IDR) & (pins setup as inputs).With that variable, I want to do something, if specific pins are HIGH, execute the if cycle.As an example, I want to execut...
I was wondering if anyone has any experience using the H723ZGT variant within Arduino IDE successfully? I followed through a tutorial on adding it as a variant to be recognized by the Arduino IDE. Tutorial Used I am at the point where I can compile t...
I have my MCU running at 1.8V and in I2C operation mode I have disabled the internal pull ups on the pins. Externally I have added pullups to 1.1V as my target device has been operating at 1.1V. Will this cause any issues?
