![]() A reverse engineer could either guess what and how the microcontroller is working or he can spend a lot of money to slice the microcontroller to gain direct access to the silicon substrate. A microcontroller is a single chip computer with internal program memory which is protected from being read. The engineer could have written software on the PC to toggle the RTS output of the UART controller to emulate a shift register, but due to various timing constraints of different laptops, he embedded a microcontroller into the multiplexor for this task. Being copies the engineer who reverse engineered the CarSoft original would have had to get it exactly right.įor example, please excuse the basic explanation if you already know microcontrol theory, but suppose CarSoft needed a serial shift device to send data between its multiplexor and an on-board car computer. ![]() For example, sometimes only way to update is to buy a new version altogether because actual internal hardware has changed from previous version.Click to expand.Unfortunately I cant say because Ive not played with them. *Disclaimer: This only applies if update is actually released by original creators. So your tool will always be up to date with current date. We'll immediately give you the update link or instructions. Product is manually tested for working condition before shipping: No dead-on-arrival situations.įuture firmware and software updates: If update comes out, you won't be left in the dark. More importantly, we're here to stay as Total Car Diagnostics is a serious established operation with too many companies relying on our 30+ years of combined mechanical/technical experience. And this experience is passed onto you when you're dealing with our support. You have free unlimited support for next 3 years with using this product: We know this tool inside-out because we're car mechanics and use it ourselves to work on customer cars. ![]()
