I followed the steps in this article which explains how to setup printf redirect to the console by generating a syscalls. Under the Template selection choose: "Display a message on PC using UART". I purchased a blackpill with STM32F401CCU6. This tutorial shows how to use the STM32F4 Discovery built-in Accelerometer, LIS3DSH. . Some changed the clock frequency some set it to the default. CHIP ST Scoll down to STM32F4 STM32F407VG (The chip on my STM32F4 discovery board) Finished.

The testcode is very simple, just create a standard template project for any stm32 (i tested this stm32f746ng), add code below somewhere.
