At the top of the code there is a section with some user changeable settings. It looks like this:
#--| USER CONFIG |-------------------------- MARK_SIZE = 10 # marker radius MARK_COLOR = 0xFF3030 # marker color MARK_THICKNESS = 5 # marker thickness TRAIL_LENGTH = 200 # trail length TRAIL_COLOR = 0xFFFF00 # trail color DATE_COLOR = 0x111111 # date color TIME_COLOR = 0x111111 # time color LAT_MAX = 80 # latitude (deg) of map top/bottom edge UPDATE_RATE = 10 # update rate in seconds #-------------------------------------------
You can change the general appearance of the circular marker using MARK_SIZE, MARK_COLOR, MARK_THICKNESS. The trail can be adjusted with TRAIL_LENGTH and TRAIL_COLOR.The data and clock color can be changed with DATE_COLOR and CLOCK_COLOR.
If you use a different map, you can adjust the vertical scaling by specifying the latitude (in degrees) of the upper and lower edges of the map with LAT_MAX. The map used for this guide was cropped at about 80deg of latitude.
You can also change the rate at which the web service is queried and the display is updated using UPDATE_RATE. However, setting this to anything lower (faster) than the default 10 isn't recommended. There's no need to query the service any faster since the amount of pixels the marker will move in 10 seconds is pretty small.
