Stm32f100 notes

Overview

This article to hold notes on early works with STMicro's STM32F100VL Discovery Board . . .

Demo Firmwares from AN3268 Standard Peripherals Library

- 2018-05-03 Thursday -

Ted working to compile, program part and run STMicro's RCC example firmware project, targeted to the STM32F100 Discovery Value Line board. Working on a Linux platform with GCC toolchain. Using professor Geoffry Brown's STM32 project template as for the project makefile or project recipe basis.

Today's goal is to build and run STM32 library example named 'RCC', locally installed in /opt/lib/an3268/stm32vldiscovery_package/Project/Examples/RCC. Having trouble with the linker not finding where built library files, likely archive or shared object files are located . . .

STM32F10x device types LD, MD, HD and Value Line

In the file /opt/lib/an3268/stm32vldiscovery_package/Libraries/CMSIS/CM3/DeviceSupport/ST/STM32F10x/stm32f10x.h there is a good explanation of the abbreviations LD, MD, HD attached to some STM32F10x microcontroller names:

  57 /*  Tip: To avoid modifying this file each time you need to switch between these
  58         devices, you can define the device in your toolchain compiler preprocessor.
  59 
  60  - Low density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
  61    where the Flash memory density ranges between 16 and 32 Kbytes.
  62  - Low-density value line devices are STM32F100xx microcontrollers where the Flash
  63    memory density ranges between 16 and 32 Kbytes.
  64  - Medium density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
  65    where the Flash memory density ranges between 64 and 128 Kbytes.
  66  - Medium-density value line devices are STM32F100xx microcontrollers where the
  67    Flash memory density ranges between 64 and 128 Kbytes.
  68  - High density devices are STM32F101xx and STM32F103xx microcontrollers where
  69    the Flash memory density ranges between 256 and 512 Kbytes.
  70  - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
  71    the Flash memory density ranges between 512 and 1024 Kbytes.
  72  - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
