I am new to Reef Angel, just picking up a RA+ unit second hand. First let me say I am impressed at the effort, the work and the functionality. It has been a while since I programmed in C++. I see the '.cpp' extension in GIT. A quick question is this C++ or Visual C++, there is a slight difference in the libraries and I was about to turf my VCP++ manual. I may keep it depending on the answer
