High Performance Low Cost Embedded Systems
The “penpad” utility is an easy to use program developed by FriendlyARM. Start it, a yellow
drawing area will show up. Draw whatever you like in the area (the pen color is black, its width is 1
pixel), go to “File” -> “Save”, you will save what you draw to a png file(in the “Documents”
subgroup, the /Documents/image/png/ directory). The file name begins with 001. The maximum
number of files that can be saved is 999. The following screenshot shows that our writing was smooth
which meant our pen was accurate.
