Lib Open-Smartwatch

A library that handles maths, animations, conversions, and drawing.

Desktop Compiling Support

You can develop the 2D stuff on your desktop, see the Readme.md in examples/. This speeds up ui development by a lot.

1. Can you explain what's the variables cx,cy,start,stop and lineradius ?

`void Graphics2D::drawArc(int32_t cx, int32_t cy, float start, float stop, uint16_t steps, uint16_t radius, uint8_t lineRadius, uint16_t color)`

cx,cy : the center coordinates of the arc
start, stop : the start and stop angles (0 is on top of the circle)
steps : number of segments used to draw the arc (bigger is smoother but slower)
radius : width/2 of the arc
lineRadius : width of the line defined as a radius of a circle drawing the line
color : 16 bytes value of the color, check rgb565(uint8_t red, uint8_t green, uint8_t blue) to create colors or use consts like BLACK, WHITE, ...
