Resolved! STM32F030 HSI clock output on MCO pin
Hi,I have configured my Nucleo-64 board with the STM32F030R8 with the STMCube software.The HSI is set as system clock (no PLL) and measured over the MCO pin (PA8). I will attach the main.c.The measurement you can see below.There are breaks within the...
Setting up I2C1 on STM32L152
I'm having a problem which appears to relate to initialisation of the I2C. When I turn on the clock to the I2C1 it sets the busy flag. Sometimes when setting up the GPIO this flag clears, sometimes it doesn't! Could someone point me at guaranteed rel...
Resolved! Easiest way to obtain a list of all STM32F446 hardware registers?
What's the easiest way to obtain a list of all STM32F446 hardware registers? Extracting them from different H-files or from the reference guide in pdf-format seems like a lot of work. Is there a more efficient way?
