1# BTstack Port for Windows Systems with DA14585 Controller connected via Serial Port 2 3This port allows to use the DA14585 connected via Serial Port with BTstack running on a Win32 host system. 4 5It first downloads the hci_585.hex firmware from the 6.0.8.509 SDK, before BTstack starts up. 6 7Please note that it does not detect if the firmware has already been downloaded, so you need to reset the DA14585 before starting an example. 8 9For production use, the HCI firmware could be flashed into the OTP and the firmware download could be skipped. 10 11Tested with the official DA14585 Dev Kit Basic on OS X and Windows 10. 12 13## Toolchain 14 15The port requires a Unix-like toolchain. We successfully used [mingw-w64](https://mingw-w64.org/doku.php) to compile and run the examples. mingw64-w64 is based on [MinGW](mingw.org), which '...provides a complete Open Source programming tool set which is suitable for the development of native MS-Windows applications, and which do not depend on any 3rd-party C-Runtime DLLs.' 16 17We've used the Msys2 package available from the [downloads page](https://mingw-w64.org/doku.php/download) on Windows 10, 64-bit and use the MSYS2 MinGW 64-bit start menu item to compile 64-bit binaries. 18 19In the MSYS2 shell, you can install everything with pacman: 20 21 $ pacman -S git 22 $ pacman -S make 23 $ pacman -S mingw-w64-x86_64-toolchain 24 $ pacman -S python 25 $ pacman -S winpty 26 27## Compilation 28 29With mingw64-w64 installed, just go to the port/windows-winusb directory and run make 30 31 $ cd btstack/port/windows-winusb 32 $ make 33 34Note: When compiling with msys2-32 bit and/or the 32-bit toolchain, compilation fails 35as `conio.h` seems to be mission. Please use msys2-64 bit with the 64-bit toolchain for now. 36 37## Console Output 38 39When running the examples in the MSYS2 shell, the console input (via btstack_stdin_support) doesn't work. It works in the older MSYS and also the regular CMD.exe environment. Another option is to install WinPTY and then start the example via WinPTY like this: 40 41 $ winpty ./spp_and_le_counter.exe 42
