In this tutorial, we are just going to port the GPIO example to the RTX RTOS (CMSIS) from the bare-metal code. TODO SAI, UART, GPIO, etc will "just work". First, we set the GPIO pins we wish to use for the I2C peripheral, enabling the appropriate alternate function (AF) mode. I have used a STM32 blue pill board to do this course, and it has the stm32f103c8t6 IC on it. The trick is to set the bit for Embedded Bare Metal Programming for STM32_NUCLEO-F446RE. Referring to the STM32F10xxx reference manual (page 51) and the memory map, we find that GPIO Port C has a base address of 0x4001-1000, while RCC is at 0x4002-1000. . STM32 bare-metal programming - Memory addressing in 32-bit system - My surprise is that when I create the project using stm32CubeMX and generating the minimum code and then substitute the main.
