Hello! I choose Codea to make an old project: an EKG simulator (and multiparameter monitor simulator) for educational purposes. I am a nurse, working and living in Chile. I work on an hospital and teaching on a University to Nursing students. So, i use a lot an early prototype and now i started from draft because i want it to put on AppStore. I also learning to code directly on XCode but i choose Codea because aircode and i can test on the fly my program. I want to show you some photos of my first prototype, working but very buggy.
Copy and paste this code, if program stops just put play again,LANDSCAPE only.
The new version is more object oriented. The precision is very low, so 60BPM actually wont run at 60/minute.
