| * Runtime environment for the BASIC interpreter, the | |
| * hardware configuration file. It contains all hardware | |
| * related settings and dependencies. | |
| * | |
| * This is hardware.h for POSIX systems and the POSIX runtime | |
| * environment runtime.c. | |
| * | |
| * Default setting is POSIX for most UNIXes including Mac. | |
| * RASPPI activates Raspberry PI related features. | |
| * MINGW activates windows related features. | |
| * MSDOS for MSDOS compiles with tc 2.0 (untested in this version, last tested in 1.4) | |

| * POSIXTERMINAL, POSIXVT52TOANSI: ensure compatibility of BASIC programs | |
| * control characters of BASIC are translated to ANSI, bringing the Aruino | |

| * POSIXSIGNALS: enables signal handling of ^C interrupting programs | |
| * POSIXNONBLOCKING: non blocking I/O to handle GET and the BREAKCHAR | |
| * tricky on DOS, not very portable, experimental, use signals instead | |
| * POSIXFRAMEBUFFER: directly draw to the frame buffer of Raspberry PI | |
| * only tested on this platform | |
| * POSIXWIRE: simple Raspberry PI wire code | |
| * POSIXMQTT: analogous to ARDUINOMQTT, send and receive MQTT messages (unfinished) | |
| * POSIXWIRING: use the (deprectated) wiring code for gpio on Raspberry Pi | |
| * POSIXPIGPIO: use the pigpio library on a Raspberry PI - currently broken - wire change - don't use | |
