The incorporation of the MKIII EAS protocol into the portable microprocessor is going slower than expected. As with everything, the process is slow in the beginning and then speeds up significantly towards the end. The primary problem is lack of avaliable used EAS ECUs on Ebay or through other part supplier sources. This means that I must literally set up all of my testing environment and several Laptops all plugged into my MKIII Rover OBDII port. This is much more difficult than just sitting down at a desk and testing. Working at the vehicle is cramped uncomfortable and each night is getting colder working in the garage. I will get there soon enough. I still expect a working prototype by this weekend.
Difficulties encoutered revolved around the differences with the input and output buffers between a PC development environment and the specific microprocessor environment.
