MPIDE WIRE LIBRARY PRO
It has been tested between a Pi, TI Launchpad, and Arduino Pro Mini. With the Virtual Wire library used on Arduinos. So a single include statement turns out project into something considerably more interesting.This module provides a 313MHz/434MHz radio interface compatible The problem with the sysprogs folks however, is they never had much of an interest in Arduino. The reality is the sysprogs VisualGDB is simply a more extensive and robust implementation with JTAG support (with a price to show for it). (there is however a VisualMicro GDB tutorial
MPIDE WIRE LIBRARY SERIAL
Alas I have a tons of "if debugging serial print" statements, as the JTAGsupport is weak. It is less expensive and fully supports the Arduino libraries. I've never been able to get VisualGDB to play well with them, so I do a lot of development with VisualMicro instead. The interesting thing here is that the library is what I call "Arduino-style". I'm using the RadioHead library and my local copy is git-cloned into \Documents\libraries\RadioHead.
MPIDE WIRE LIBRARY CODE
Tinkering with LoRa stuff, and being able to single-step debug the code will be helpful. So that all is your basic VisualGDB project. Gpio_set_level(static_cast(BLINK_GPIO), 1) Gpio_set_level(static_cast(BLINK_GPIO), 0) Gpio_set_direction(static_cast(BLINK_GPIO), GPIO_MODE_OUTPUT) In the case of this blink app, BLINK_GPIO is simply defined as "2" with no type. (hopefully in a future release, sysprogs will give the option of using C or C++ sample templates). The first thing we'll need to do is take thatįile and rename it to something like main.cpp and make a few other changes.

In the Ardunio IDE, File-New creates something like this (note no "main"): (Update 4/28: some final editing still in progress)įirst, the Arduino "sketch" is an odd critter, so close to being C/C++ but just enough different that some people have even called Arduino a language of its own.
