Not far in and I have already encountered a problem. When running my simple script that worked out the frames per second of the screen the CPU usage averaged at 86%. Whilst running other scripts (mainly recording audio), this could be a problem with not having enough processing power to run the program. 

Solution - A SPI OLED uses more GPIO pins but has a higher refresh rate and lower CPU usage. Adding one of these instead of the I2C screen would help.
