Re: TI and future Jaguars

I've separated the post because I changed topic:

One nice part about the modular solution is that we can keep reusing parts and if we want to include something complicated we can make that one part while leveraging the other. For example we could make a Jaguar compatible module with an electronically similar CAN interface as an interface to the high power module. We could also make a CAN module with a different interface then the Jaguar but still CAN. We could make a single PWM module that looks similar to a Victor, but can also have it's performance tweeked to have a wider response range or a different carrier frequency (one single PWM module different software personalities). If someone wanted to they could take an ARM9 and make a speed control with multiple high power modules (one interface multiple motors).

When it comes to the interface modules not connected to the 'custom circuit module' we'll need someway to insure that the code FIRST approves is actually within the core of that module. Currently FIRST achieves this because the Victor is one time programmable and the Jaguar has it's FIRST firmware effectively checked. We could make it so that FIRST can check the firmware with a tool quickly (in-circuit programming would allow a quick comparison when the interface is PWM, we already do this with the CAN to some extent). We can make it so that the modules approved by FIRST are one time programmable. Then again we could encase the programming circuit mechanically to make it tamper evident. In any case we'll probably be required to provide this protection to keep the FIRST playing field equal.
