This example flashes available LEDs on supported boards, one by one.

Detailed description

See theCore documentation for blinky example for more information.

Supported targets (boards)

Target name	Configuration file	Description
stm32f4_disc	stm32f4_discovery.json	STM32F4 discovery board
tiva_tm4c_launchpad	tiva_tm4c_launchpad.json	TM4C123G LaunchPad Evaluation Kit

Quick start

1. Install theCore (this may take a while):

   pip3 install tcore
   tcore bootstrap
   

2. Download this example:

   tcore init --remote https://github.com/theCore-embedded/example_blinky
   

3. Step into the project directory:

   cd example_blinky
   

4. Compile:

   • For STM32 Discovery board:

     tcore compile --target stm32f4_disc
     

   • For Tiva TM4C LaunchPad:

     tcore compile --target tiva_tm4c_launchpad
     

5. Connect your board.

6. Run:

   • For TivaC launchpad:

     tcore flash --sudo
     

   • For old STM32F407G-DISC boards, with STLINK/V2:

     tcore flash --sudo
     

   • For new STM32F407G-DISC1 boards, with STLINK/V2.1:

     tcore flash --sudo --debugger-config stlink-v2.1
     

7. Observe LEDs blinking on your board.

"Error: open failed" while running openocd

Hi,

I had to change the line
source [find interface/stlink-v2.cfg]
to
source [find interface/stlink-v2-1.cfg]
otherwise I get

Hello,
I'm using CMake 3.9.6. I got this error while going through instructions listed in README.md.

Setup nightly travis builds

Due to constant changes in Nix environment and some updates, blinky project can be failed to build, as #3 demonstrates.
