Step 7: Install CMake

Get latest X86 version from https://cmake.org/files/

Example: cmake-3.2.1-win32-x86.exe

Install it to C:\CMake

Step 8: Add cmake to PATH and check

C:\>set PATH=%PATH%;c:\CMake\bin

C:\>cmake --version
cmake version 3.2.1

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Step 9: Download Ninja

download install ninja

Unzip ninja-win.zip to c:\CMake\bin this path is already in PATH

Step 10: Check ninja

C:\>ninja --version
1.10.0

Step 11: Create a directory "blinky"

C:\>mkdir blinky

C:\>cd blinky

C:\blinky>

Step 12: Create Yotta Blinky Project

C:\blinky>yotta init
Enter the module name: <blinky>
Enter the initial version: <0.0.0> 1.0.0
Is this an executable (instead of a re-usable library module)? <no> yes
Short description: example 1
Author: Me
What is the license for this project (Apache-2.0, ISC, MIT etc.)?  <Apache-2.0>

Step 13: Target board STM32

C:\blinky>yotta target stm32f429i-disco-gcc
info: get versions for stm32f429i-disco-gcc
info: download stm32f429i-disco-gcc@0.0.20 from the public module registry
info: get versions for mbed-gcc
info: download mbed-gcc@1.2.2 from the public module registry

Step 14: Install Drivers

C:\blinky>yotta install mbed-drivers
info: mbed-drivers, *
info: get versions for mbed-drivers
info: download mbed-drivers@1.5.0 from the public module registry
info: dependency mbed-drivers: ^1.5.0 written to module.json
info: get versions for mbed-hal
info: download mbed-hal@1.3.0 from the public module registry
info: get versions for cmsis-core
info: download cmsis-core@1.2.0 from the public module registry
info: get versions for ualloc
info: download ualloc@1.3.0 from the public module registry
info: get versions for minar
info: download minar@1.3.0 from the public module registry
info: get versions for core-util
info: download core-util@1.8.0 from the public module registry
info: get versions for compiler-polyfill
info: download compiler-polyfill@1.3.0 from the public module registry
info: get versions for greentea-client
info: download greentea-client@1.1.0 from the public module registry
info: get versions for mbed-hal-st
info: download mbed-hal-st@1.0.0 from the public module registry
info: get versions for mbed-hal-st-stm32f4
info: download mbed-hal-st-stm32f4@1.3.5 from the public module registry
info: get versions for uvisor-lib
info: download uvisor-lib@2.1.2 from the public module registry
info: get versions for mbed-hal-st-stm32cubef4
info: download mbed-hal-st-stm32cubef4@1.2.0 from the public module registry
info: get versions for mbed-hal-st-stm32f429zi
info: download mbed-hal-st-stm32f429zi@1.1.0 from the public module registry

Step 15: XPM Windows build tools

C:\blinky>xpm install --global @xpack-dev-tools/windows-build-tools@latest

 Step 16: XPM ARM gcc

C:\blinky>xpm install --global @xpack-dev-tools/arm-none-eabi-gcc@latest

 Step 17: XPM ARM QEMU

C:\blinky>xpm install --global @xpack-dev-tools/qemu-arm@latest

Step 18: Add gcc to path

C:\>set PATH=%PATH%;C:\Users\<your home>\AppData\Roaming\xPacks\@xpack-dev-tools\arm-none-eabi-gcc\9.3.1-1.1.1\.content\bin

C:\>set PATH=%PATH%;C:\Users\<your home>\AppData\Roaming\xPacks\@xpack-dev-tools\arm-none-eabi-gcc\9.3.1-1.1.1\.content\arm-none-eabi\bin

Please replace <your home> to proper folder name

Step 19: Add emulator to path

C:\>set PATH=%PATH%;C:\Users\<your home>\AppData\Roaming\xPacks\@xpack-dev-tools\qemu-arm\2.8.0-9.1\.content\bin

Please replace <your home> to proper folder name

Step 20: Write your code -- C:\blinky\source\app.cpp

#include "mbed-drivers/mbed.h"
 
static void blinky(void) {
    static DigitalOut led1(LED1);
    static DigitalOut led2(LED2);
    led1 = 1;
    led2 = 1;
}
 
void app_start(int, char**) {
    while(1) {
        blinky();
    }
}

put this code as "app.cpp" inside C:\blinky\source

Step 21: Compile

C:\blinky>yotta build

Step 22: Run the code

qemu-system-gnuarmeclipse -board STM32F429I-Discovery -mcu STM32F429ZI -image .\blinky\build\stm32f429i-disco-gcc\source\blinky.bin
