air-pencil's Introduction

README

A project with STM32F103RB is called air pencil. Using FreeRTOS, SPL, auto build with make and require arm-none-eabi-gcc-4.8.4 or newer. Hardware requirements:

STM32F103RB ARM Cortex-M3 MCU (ST Microelectronics)
ADXL345 Digital Accelerometer (Analog Devices)
ITG3200 Digital Gyroscope (InvenSense)
J-Link BASE hardware v9.x (Segger - older versions not support for Linux)

Flash Programming with J-Link

So, let's go with J-Link Software Pack installation:

Download J-Link Software Pack installation at https://www.segger.com/downloads/jlink/
In download folder, run: sudo dpkg --install <name-of-jlink-installer>

Connect MCU board to debugger. Run J-Link commander:

In terminal, run JLinkExe
With prompt displayed as J-Link, type connect (you can see like J-Link>connect)
With prompt displayed as Device, type name of MCU line (you can see like Device>STM32F103RB)
With prompt displayed as TIF, type representing symbol of interface you wanna use (I choose SWD, like TIF>S)
With prompt displayed as Speed, type operation frequency of interface (e.g. TIF>1000, unit as kHz). If you complete all step above, you'll be received a message as Cortex-M3 identified. and prompt will be displayed as J-Link

To load data file into target memory, you can use syntax:

loadfile <filename>, [<addr>], supported extensions: *.bin, *.mot, *.hex, *.srec and is needed for bin files only or simple
loadbin <filename>, <addr> with only *.bin files. In there, is the first memory address of the flash area (see more in linker file)
E.g.: loadbin demo.bin, 0x0800000
