GCC Toolchain for CoreSTM32

Why GCC toolchain 100% opensource and free Controll everything of CoreSTM32 Discover 100% power of STM32 micro processor. Much higher performance compared to Maple IDE. Setting up GCC toolchain You have two choices: GCC for ARM. https://launchpad.net/gcc-arm-embedded OR Sourcery CodeBench Lite(formerly Code Soucery). http://www.mentor.com/embedded-software/sourcery-tools/sourcery-codebench/editions/lite-edition/ It is said that Sourcery CodeBench Lite has better performance than other compilers, but we haven't made any test. Using IDE(Integrated Development Environment) I prefer Eclipse, but you have multiple choices, like Eclipse: http://www.eclipse.org/downloads CooCox IDE(Eclipse based): http://www.coocox.org/index.html Code::Blocks: http://www.codeproject.com/Tips/601093/Creating-STM-Microcontroller-Project-in-Code-Blo Setting up Eclipse and GNU ARM plugin In order to use Eclipse you should first download a Java Runtime, or you can use Java within Arduino IDE. Find your "System Preference", add environment variables for Java: PATH and JAVA_HOME, you can find tutorials online. Download Eclipse for C/C++ : http://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/lunar Extract eclipse files, run eclipse.exe Click Help->Install New Software Install GNU ARM plugin for Eclipse Follow the instructions on http://gnuarmeclipse.livius.net/blog/plugins-install/ Testing Program: Blink #include "stm32f10x.h" #include "stm32f10x_gpio.h" #include "stm32f10x_rcc.h" int main(void) { int i; GPIO_InitTypeDef GPIO_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOA, &GPIO_InitStructure); while (1) { GPIO_SetBits(GPIOA, GPIO_Pin_8); /* delay */ for (i = 0; i < 0x1000000; i++) ; GPIO_ResetBits(GPIOA, GPIO_Pin_8); /* delay */ for (i = 0; i < 0x1000000; i++) ; } }
