STM32 Read Device ID Exercise

Task

When a new board arrives, an engineer checks two things first. Does their code really run, and is the chip the model they expected? The chip can answer that itself. Its model number is inside it, at a fixed address.

Read this chip's model number and print it, like this: ID:0x10076413 The address is in the Datasheet tab, under DBG.

Circuit

Pass condition

The line shows the ID code of the part under test. Each test runs on a different STM32F4.
