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 13The port provides both a regular Makefile as well as a CMake build file. It uses native Win32 APIs for file access and does not require the Cygwin or mingw64 build/runtine. All examples can also be build with Visual Studio 2022 (e.g. Community Edition). 14 15## Visual Studio 2022 16 17Visual Studio can directly open the provided `port/windows-windows-h4-da14585/CMakeLists.txt` and allows to compile and run all examples. 18 19## mingw64 20 21It can also be compiles with a regular Unix-style toolchain like [mingw-w64](https://www.mingw-w64.org). 22mingw64-w64 is based on [MinGW](https://en.wikipedia.org/wiki/MinGW), 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.' 23 24We've used the Msys2 package available from the [downloads page](https://www.mingw-w64.org/downloads/) on Windows 10, 64-bit and use the MSYS2 MinGW 64-bit start menu item to compile 64-bit binaries. 25 26In the MSYS2 shell, you can install everything with pacman: 27 28 $ pacman -S git 29 $ pacman -S make 30 $ pacman -S mingw-w64-x86_64-toolchain 31 $ pacman -S python 32 $ pacman -S winpty 33 34### Compilation 35 36With mingw64-w64 installed, just go to the port/windows-h4-da14585 directory and run make 37 38 $ cd port/windows-h4-da14585 39 $ make 40 41Note: When compiling with msys2-32 bit and/or the 32-bit toolchain, compilation fails 42as `conio.h` seems to be mission. Please use msys2-64 bit with the 64-bit toolchain for now. 43 44## Console Output 45 46When 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: 47 48 $ winpty ./gatt_counter.exe 49 50The packet log will be written to hci_dump.pklg 51
