Mixing
Reading a text file data and displaying it into LCD (ARM Language)

I need to read integer data from a text file representing current values and measure them interactively they should be shown in the LCD display and if a current value is greater than a threshold value the the left LED should be fired. At the end the RMS value and the mean value should be presented on the LCD display. Since this is simulation only, I'm using ARMSim# (version 1.9.1) to achieve that, unfortunetly my skills in ARM programming are limited. I gathered some info which led me to this until now (it is not working and I need a lot of advice to be really able to simulate this)
