I'm making a medical pump unit, which I want the owner to be able to reprogram via a laptop.
All of the reprogrammable information will be variables stored in the EEPROM of an 18X Picaxe. I would like to communicate via the laptop USB port and write a VB program as a user friendly front end. I am aware I need to use the SERIN and SEROUT commands in Picaxe, but I'm a bit lost from there on.
Any tutorials or examples would be appreciated.
