I'm just getting started with microcontrollers in general. I have done some work with the 68hc11; I used a decompiler to take apart the code for my car and with the help of others added in some new features. Now I want to move further and use a microcontroller to do so some of the things the ECU cannot do (well...without a lot more work anyway).
I'm planning on using the controller in my car so something that can run on 12v would be nice though if a better controller uses a different voltage I can get a power supply. I need it to be able to monitor the voltage of 10 different sensors so 10 analogue input pins with good resolution in the 0-5v range, output 0-5v on at least 2 pins, and have at least 2 digital pins for a led and a relay signal. It needs to be a least as fast as the 68HC11 (react quickly to changes in sensor data when the engine it spinning at max rpm). Past that I would prefer to start with something I can hook directly to my laptop (serial, USB, or Parallel is fine) to program and as always; the smaller the better. I would also consider one that had a good direct connect version that is larger (for learning and testing) and a smaller version that meets these criteria I could use with an external programmer for a finished project.
I'm not too concerned with how hard it is learning the language; I'm in no rush. Price wise...well I obviously don't want to spend more than I need to. I feel a bit foolish asking this, I know I don't have a simple project in mind and am tackleing a lot. I just want to start with the right microcontroller so I don't invest all my time learning something that cannot do what I want. Thank you.
