# memtemp shows memory infos and cpu temperature
#
# mem usage, cpu load, cpu temp

# Updated 18-10-2019 by spees <speeskonijn@gmail.com>
# - Changed the place where the data was displayed on screen
# - Made the data a bit more compact and easier to read
# - removed the label so we wont waste screen space
# - Updated version to 1.0.1
#
# 20-10-2019 by spees <speeskonijn@gmail.com>
# - Refactored to use the already existing functions
# - Now only shows memory usage in percentage
# - Added CPU load
# - Added horizontal and vertical orientation
