I'm using STM32CubeIDE/MX to program and debug a simple demonstration of UART on the B-L475E-IOT01A development board (with integrated STM32L475VG). The code is straightforward (and autogenerated, apart from the hello world message).Probing the pins ...

I'm trying to get a very simple example working with the DAC on the STM32L475VG in the B-L475E-IOT01A development board. I've generated the code below with STM32CubeMX for use in STM32CubeIDE. I can see the DAC register values changing, and LD1 blink...

So! The problem here is that if you start from a clear pinout, the default pins for USART1 RX/TX are not the pins connected to ST-LINK. I only discovered this by going and seeing what a default configuration looks like in another context, and noticed...

I figured out the problem, and it was indeed something simple that I was missing, but you can't tell it from the code. The code was fine. I was just probing the wrong pins on the Arduino Uno interface, because apparently I don't read schematics caref...

TDK,I haven't changed HAL_DAC_MspInit(); here is the generated source. It does appear that the related clocks are initialized. Do I have to manually call this someplace? Or is it handled by HAL_DAC_Init()? There's no place in main that refers to this...
